The Aquarium Lecture Series is presented free to the public through the generosity of the Lowell Institute. Look back at some of our recent speakers; some lectures have been recorded.
Right Whales, Right Gear: Finding New Ways to Fish that Avoid Entanglements
Panel discussion with John Haviland, South Shore Lobster Fishermen’s Association; Laurens Howle, Duke University; Amy Knowlton, Senior Scientist, Anderson Cabot Center for Ocean Life at the New England Aquarium; and Kristan Porter, President, Maine Lobstermen’s Association
Moderated by Tim Werner, Senior Scientist, Anderson Cabot Center for Ocean Life at the New England Aquarium, and Director, Consortium for Wildlife Bycatch Reduction
Fishing is an important economic mainstay of New England and part of its cultural heritage. North Atlantic right whales are a critical natural component of the region’s coastal waters. Where the two meet, entanglements happen, mainly as whales become wrapped in buoy ropes used to locate and haul pots resting on the seafloor. Two unlikely bedfellows—fishermen and research scientists—are working collaboratively to save whales and pot fisheries alike, studying solutions that include novel designs for ropes that are strong enough for fishing but weak enough for right whales to release themselves. Come listen to members of an expert panel discuss their perspectives on right whale entanglements and ideas for solving them.
Marine Mammals in the Anthropocene: Keeping Endangered from Becoming Extinct
Scott Kraus, Ph.D., Vice President and Senior Science Advisor, Anderson Cabot Center for Ocean Life at the New England Aquarium
Recent marine extinctions suggest that humanity does not have a good record of coexisting with marine mammals. Given continuing human population growth, ocean industrialization will expand, raising questions about the balance between human needs and wildlife. This is a battle that marine mammals are currently losing, but there are actions we can take to change the outcome.
First, we scientists should get better at telling our story—why wildlife matters, how marine mammals are a critical part of a functioning ecosystem, why human activities continue to threaten both marine mammals and the oceans, and no, the whales are not saved yet. Endangered species need constituencies and public support, and most don’t have enough. Second, assessment methods for rare species need improvement. Elegant population and viability models may be of limited utility in small populations because inherently small sample sizes yield large variances with little ability to detect trends. Other robust biological signals can be better at predicting impending changes in small populations. Third, small populations of marine mammals require more protected habitat, better definitions of what that means, and prohibitions on harmful activities in those areas. For some marine mammals this may mean protecting migratory corridors, from breeding to feeding grounds, across international boundaries. Fourth, the permitting and funding of rare population conservation and recovery efforts are inadequate, partly because of limited public support. Finally, although counterintuitive, scientists should work with all stakeholders, including the oil, gas, and seismic industry, the fishing industry, wind utilities, and aquaculture facilities, to help them make their activities less detrimental. We do not yet have a collective view of how marine mammals will survive in an industrialized ocean, but if we take these steps, the next generation of scientists will be able to bring a vision of coexistence closer to reality.
Distance Vision and the Early Origins of Awareness
David Edelman, Ph.D., Visiting Scholar, Department of Psychological and Brain Sciences, Dartmouth College
The ability to resolve distant objects within a complex visual scene probably emerged more than 500 million years ago during the Cambrian explosion, a period characterized by the appearance of diverse new sensory innovations, including every major type of eye found in living vertebrates and invertebrates today. David Edelman, Ph.D., argues that distance vision and its underlying neural circuitry provided the first critical substrates for sensory consciousness. Seeing objects from afar engendered a new sort of neural faculty that effectively linked space and time. Animals equipped with this faculty were able to not only monitor their environment for salience (e.g., identify and track predators or prey), but also make predictions about future outcomes on which their survival likely hinged. Making such predictions must necessarily have relied on an ongoing linkage between perception and memory: a connection that, some suggest, is a critical requisite for conscious experience. He makes the case that, as a capable predator with acute vision, the octopus provides a striking test case for subjective experience in an animal quite distant from the vertebrate line. Indeed, probing the octopus visual system could conceivably help identify neuroanatomical and neurophysiological properties of conscious states that are universal among animals with sophisticated sensory faculties and complex nervous systems, regardless of profound morphological differences and divergent evolutionary histories.
Boston Harbor for All: The Mayors’ Perspective
Mayor Martin J. Walsh of Boston
Mayor Kim Driscoll of Salem
Mayor Thomas McGee of Lynn
A discussion with Mayor Martin J. Walsh of Boston, Mayor Kim Driscoll of Salem, Mayor Thomas McGee of Lynn, and other leaders on Boston Harbor’s role in the regional economy, climate resilience, public access and open space, water transportation, and public health and well-being. Boston Harbor is at a critical moment in history. In an era of climate change and a building boom, how do we work together to create a waterfront that is accessible and resilient – truly a harbor for all?
Our collective success in cleaning up the harbor has created a new set of opportunities and urgent challenges. The planning and design decisions we make today will impact our waterfront for decades to come. Only by collaborating and breaking down silos will we get it right.
THIS LECTURE WAS CO-HOSTED BY BOSTON HARBOR NOW AND THE NEW ENGLAND AQUARIUM.
Seal Studies: What Aquarium Scientists Are Learning About Disease, Physiology, and Population Dynamics to Help Protect Seals
A talk by three seal experts with the New England Aquarium
- Patty Schilling, Marine Mammal Supervisor, New England Aquarium
- Katherine Graham, M.S., Assistant Scientist, Anderson Cabot Center for Ocean Life at the New England Aquarium
- Katie Pugliares-Bonner, M.S., Senior Biologist – Necropsy Specialist, New England Aquarium Marine Animal Rescue and Rehabilitation Department
Pinnipeds are a diverse group of marine mammals that engender curiosity and fascination. The New England Aquarium has been working with, studying, and rescuing seals for years. This evening’s lecture gives you a closer look at the work being done to better understand the seals here at the Aquarium as well as their wild counterparts.
- Patty Schilling, Marine Mammal Supervisor, New England Aquarium, has been a marine mammal trainer at Aquarium for 13 years. She provides care, training, and enrichment for the Aquarium’s collection of marine mammals, including the northern fur seals. As part of her job, she has also had the opportunity to participate in NOAA Fisheries’ biennial northern fur seal population counts in St. Paul Island, Alaska. Patty will share information about these experiences, including the current population status of the northern fur seal
- Katherine Graham is developing methods to study the complex reproductive physiology of northern fur seals using noninvasive fecal hormone analysis. This collaborative project aims to better understand reproductive patterns of seals in aquariums, including those at the New England Aquarium, with potential future application of these techniques to study wild populations of northern fur seals.
- The Aquarium’s Rescue and Rehabilitation Department is responsible for responding to reports of live and dead marine mammals from Salem, MA, south through Plymouth, MA. Katie Pugliares-Bonner will speak about her investigations into and the discovery of novel and emerging disease conditions found during necropsies (animal autopsies) of local stranded pinnipeds as well as the collective efforts of the rescue team.
Atlantic Salmon – Lost at Sea, film screening and discussion
Introduction by the film’s producer, Deirdre Brennan, followed by a question-and-answer session with Jonathan Carr, Vice President of Research and Environment, Atlantic Salmon Federation
Co-hosted by the Atlantic Salmon Federation and the National Oceanic and Atmospheric Administration
Narrated by Irish actor and film director Gabriel Byrne, Lost at Sea takes the viewer on an epic journey through the oceanic kingdom of the Atlantic salmon–king of fish–in an attempt to unravel the mystery of their life at sea. Populations of salmon are plummeting to critical levels, even going extinct in some southern rivers. Despite conservation efforts worldwide, populations continue to fall. The cause is mortality at sea.
For the first time, scientists, using the latest DNA technology, are able to track the salmon from the rivers, through the estuaries, and into the vast North Atlantic Ocean and back again, in hopes of finding an answer before it is too late.
Brian Skerry, National Geographic Photographer and New England Aquarium Explorer In Residence
Brian Skerry saw his first shark in the wild in 1982 and was hooked. During the last three and a half decades, he has spent countless hours underwater in locations worldwide photographing these enigmatic animals.
In this presentation, Brian will share his personal journey with sharks, from the ways that he’s been inspired by them to his approach with photography and what he has learned along the way. Among the species to be highlighted will be tiger sharks, makos, oceanic whitetips, and great whites. His latest book for children is entitled The Ultimate Book of Sharks.
Return of the Sea Otter – America’s Cutest Animal
Todd McLeish, Science Writer
Sea otters were nearly driven to extinction during the fur trade in the late 1700s and 1800s, but they have recolonized most of their former range and have become one of the most popular–and cutest–animals in America. While their population is growing in many areas, they are still threatened by sharks, killer whales, oil spills, fishermen, and native hunters. Join author Todd McLeish as he shares adorable photos and describes his adventures studying sea otters from California to Alaska. This will be Todd’s first presentation of his new book, Return of the Sea Otter, and he will sign copies of the book in the IMAX lobby following his lecture.
One Life at a Time – Saving Sea Turtles in Ghana
John Flynn, co-founder and director of Wildseas and New England Aquarium Marine Conservation Action Fund Fellow*
During a 2011 visit to the western region of Ghana, Marine Conservation Action Fund (MCAF) Fellow John Flynn and his colleague Neil Davis witnessed the rampant poaching of nesting sea turtles and their eggs. They reached out to local village chiefs, recruited a dedicated team from the community, and began nightly beach patrols to deter poachers. Within a few years, Flynn, Davis, local anti-poaching patrol leader Enock Agyimah, and numerous seasonal staff helped protect thousands of turtle eggs and many nesting turtles from poachers. The conservation mission of the group, known as Wildseas, soon grew beyond protecting sea turtle nesting beaches.
In 2012, Flynn and Davis’ interpreter, Eric Quayson, alerted them to high bycatch rates of sea turtles in offshore fishing nets. Working with Quayson, who served as a liaison to the fishing community, Flynn and Davis secured a commitment from the fishermen to safely release turtles caught in their nets. This collaborative safe-release program has saved nearly 1,000 turtles since 2012. Flynn will speak about the many challenges and successes he and his team have experienced in their efforts to save turtles, collaborate with fishermen, engage local communities, and build local capacity for conservation.

Protecting Stellwagen Bank: A History of the Sanctuary – 25 Years and Moving Forward
Richard Delaney, President and CEO of the Center for Coastal Studies, and Ben Haskell, Acting Superintendent of the Stellwagen Bank National Marine Sanctuary
More than 25 years ago, threats to an underwater bank at the mouth of Massachusetts Bay abounded. Construction teams considered the sand and gravel fair game for the Big Dig, and a developer posited a plan for a casino complex on an oil-rig-like platform. Luckily, whales, fish, and the backing of thousands of whale watchers, students, fishermen, and environmentalists sank those ideas. The productive region around Stellwagen Bank was designated a national marine sanctuary in 1992. Rich Delaney, President and CEO of the Center for Coastal Studies (which nominated Stellwagen Bank for sanctuary status), had served as director of the Mass. Coastal Zone Management Office during the process to create a sanctuary. Ben Haskell, the sanctuary’s acting superintendent, leads a team of researchers and educators who work to understand and protect this special place. They will provide a retrospective of the first 25 years of New England’s only national marine sanctuary and a vision for the next 25 years.
A Carbon-Free and Climate-Ready Boston
Austin Blackmon, Chief of Environment, Energy and Open Space for the City of Boston
Since 1991, Boston has experienced 21 events that triggered federal or state disaster declarations. For example, in 2011, Hurricane Irene caused downed trees and power outages across the city. In 2012, while Boston was spared the most devastating effects of Hurricane Sandy due to the storm missing Boston’s high tide by five hours, the city still experienced high winds and coastal flooding. As the climate changes, the likelihood of coastal and riverine flooding—as well as other hazards, like stormwater flooding and extreme heat—will increase.
The challenges from climate change are substantial and complex but can be addressed through bold and creative actions that support the city’s vitality and livability. Boston can thrive in the coming decades if it takes action to adapt its people, its neighborhoods, and its economic and cultural assets, starting now. This work will be difficult, contentious, and complex. But if done well, it will not only create a resilient, climate-ready Boston, it will also dramatically improve the city and quality of life for all its residents.
Science Priorities for the North Atlantic Region – A NOAA Fisheries Perspective
Jon Hare, Ph.D., Science and Research Director, Northeast Fisheries Science Center
The mission of NOAA Fisheries is compelling and important. The agency is responsible for the stewardship of the nation’s living marine resources, including fisheries, aquaculture, protected species, habitats, and ecosystems. As Science and Research Director of the NOAA Fisheries Northeast Fisheries Science Center (NEFSC), Jon Hare is responsible for the Northeast U.S. Shelf Ecosystem, which extends from North Carolina to Maine and includes watersheds, estuaries, the continental shelf, and the open ocean. The ecosystem supports a wide array of living marine resources, from Atlantic sea scallops, one of the most valuable, to the North Atlantic right whale, one of the most endangered, to Atlantic cod, one of the most iconic. A set of science priorities will be described for the region. These priorities aim to better understand this complex ecosystem and ultimately improve the stewardship mission of NOAA Fisheries.
Changing Distributions of Large Whales: How Climate, Oceanography, and Biology Influence Movement of the Largest Animals on Earth
Dan Pendleton, Ph.D., Research Scientist, Anderson Cabot Center for Ocean Life at the New England Aquarium
The mystery of how and why large whales know when and where to migrate has perplexed humankind for thousands of years – first in their attempts to hunt and kill them and now to save them from extinction and exploitation. Right and bowhead whales are among the largest animals on Earth, yet they feed on some of the smallest marine organisms, zooplankton. This connection through the food web dramatically highlights associations of species linked closely to climate-induced changes in the oceans, such as recent rapid warming of the Gulf of Maine. Large filter-feeding whales, as ecological sentinels, are therefore a highly visible sign of underlying ocean health and conditions. This lecture will explore pressing questions surrounding large whale conservation and describe cutting-edge quantitative methods being used to understand whale distributions in the Anthropocene.
Conservation of Scalloped Hammerhead Sharks in Costa Rica
Enrique Uribe, Board Member and Sustainability Manager, Misión Tiburón
The scalloped hammerhead shark is an endangered species threatened by overfishing, bycatch, and the shark fin trade. Scientist Andres Lopez and his partner, Ilena Zanella, founded Misión Tiburón (Shark Mission) in Costa Rica to study and protect these charismatic animals. Through their years of research and tagging studies they have identified the sharks’ critical nursery habitats and helped to enact national and international conservation measures, including CITES listings, to better protect these animals. This work was supported in part by the New England Aquarium’s Marine Conservation Action Fund (MCAF). Lopez and Zanella have also engaged fishermen, communities, government officials, and schoolchildren in their conservation efforts, growing a vital and broad base of support for the sharks. Join us to hear MCAF Fellow Andres Lopez and his colleague Enrique Uribe speak about Misión Tiburón’s comprehensive approach to shark conservation in Costa Rica and their efforts to promote a shark sanctuary in Golfo Dulce, a critical nursery habitat on the country’s Pacific coast.
The MCAF Ocean Conservation Fellows Program is supported in part by the Institute of Museum and Library Services.
A Brief History of Environmental Successes
Susan Solomon, Ph.D., Lee and Geraldine Martin Professor of Environmental Studies, Massachusetts Institute of Technology
This is the seventh annual John H. Carlson Lecture, presented by Massachusetts Institute of Technology’s Lorenz Center and the New England Aquarium.
Humans have faced a series of national and global environmental challenges in the past half-century, including smog, the use of lead in gasoline, ozone depletion, and many others. Dr. Susan Solomon reveals how combinations of science, public policy, industry participation, and the engagement of citizens succeeded in addressing past environmental challenges. Solomon also probes how the lessons learned help us understand how to better manage today’s environmental problems, including climate change.
Dr. Solomon is internationally recognized as a leader in atmospheric science, particularly for her insights in explaining the cause of the Antarctic ozone “hole.” She and her colleagues have also made important contributions to understanding chemistry/climate coupling, including leading research on the irreversibility of global warming linked to anthropogenic carbon dioxide emissions, and on the influence of the ozone hole on the climate of the Southern Hemisphere. Her current research focuses on both atmospheric chemistry and climate change.
The John Carlson Lecture communicates exciting new results in climate science to the public. The free and public lecture is made possible by a generous gift from MIT alumnus John H. Carlson to the Lorenz Center in the Department of Earth, Atmospheric and Planetary Sciences, MIT.
Crazy Weather and the Arctic Meltdown: How Are They Connected?
Jennifer Francis, Ph.D., Research Professor I, Department of Marine and Coastal Sciences, Rutgers University
Does it seem as though the weather gods have gone crazy lately? It is not your imagination. The question on everyone’s minds is why? And is it related to climate change? In this presentation, Dr. Jennifer Francis will explain new research that links increasing extreme weather events with the rapidly warming and melting Arctic during recent decades. Evidence suggests that Arctic warming is causing weather patterns to become more persistent, which can lead to extremes such as droughts, cold spells, heat waves, and some flooding events.
Facilitating Productive Dialogue about Climate Change
William Spitzer, Ph.D., Vice President, Programs, Exhibits, and Planning, New England Aquarium
and panel discussion with
Nicole Killebrew, Seattle Aquarium
Jennifer Stoddard, Reid Park Zoo in Tucson
Jennifer West, Narragansett Bay National Estuarine Research Reserve
We can all learn to start positive conversations about climate change. Educators and professional scientists affiliated with aquariums, zoos, and other museums from across the country are learning and helping to model the way with public audiences. We’ll share some key insights that you can use from social and cognitive sciences that are proving to be useful in shaping engaging, solutions-focused conversations.
William Spitzer, Ph.D., Vice President, Programs, Exhibits, and Planning at the New England Aquarium, will briefly review the history and evaluation that illustrates the positive impacts of the National Network for Ocean and Climate Change Interpretation (NNOCCI), a project led by New England Aquarium along with an interdisciplinary team of colleagues from several partner organizations. Dr. Spitzer will moderate a panel discussion with three educators from across the U.S. who participated in NNOCCI training programs. The panelists are Nicole Killebrew of the Seattle Aquarium, Jennifer Stoddard of Reid Park Zoo in Tucson, and Jennifer West of the Narragansett Bay National Estuarine Research Reserve. Panelists will share reflections from their experiences to illustrate how lessons about Strategic Framing have influenced their climate change communications. The program will offer some specific ideas as well as inspiration for people interested in talking about climate change in productive ways.
Climate Change along the Western Antarctic Peninsula
Scott Doney, Ph.D., Joe D. and Helen J. Kington Professor in Environmental Change, Department of Environmental Sciences, University of Virginia
The western Antarctic Peninsula is experiencing some of the most dramatic climate change on the planet and is a natural laboratory for studying how ocean ecosystems respond to climate. Rapid ocean-atmosphere warming, melting of coastal glaciers, and reductions in seasonal ice cover all echo throughout the marine food web from seawater chemistry, plankton, and krill to top predators, including penguins and marine mammals. Using the wealth of data from the Palmer Long-Term Ecological Research (LTER) programs, the talk will highlight key lessons from field expeditions, autonomous robots, satellite remote sensing, and models regarding changing conditions in the Southern Ocean and Antarctic.
Extreme Events and Climate Change: What We Know and What We Can Do
Ellen Marie Douglas, PE, Ph.D., Associate Professor of Hydrology, School for the Environment, University of Massachusetts Boston
There are three truths that climate science tells us about what we can expect from climate change. The first is small changes in an average value, such as average global temperatures, will have bigger effects on the extremes. We have seen this play out in the extreme weather events that have wrought havoc across New England and the nation over the last decade or longer. Record-breaking events will always occur, but the time between these events should increase. Under climate change, records are getting broken in record time! The second truth is that our history of carbon dioxide emissions has embedded a certain amount of change into the climate system, to which we will need to adapt. The third truth is that if we don’t account for our changing climate in planning and designing, our plans and designs will be wrong. In this presentation, Ellen Marie Douglas will discuss observations of our changing climate, what changes may be in Boston’s future, and some plans for how to adapt to these changes.
This lecture was co-hosted by the League of Women Voters of Boston and Massachusetts and the University of Massachusetts Boston School for the Environment.
African Manatees and Sea Turtles: Conservation Challenges and Successes
For more than two decades, scientists Lucy Keith-Diagne and Tomas Diagne have been studying manatees and turtles and advocating for their protection. During the last 11 years, Lucy has focused her research on the African manatee, which is one of the least understood of the world’s marine mammals and is often referred to as the “forgotten sirenian.” African manatees live in 21 countries on the western side of the continent, along coasts, and up to 3,000 kilometers inland. They are highly susceptible to accidental capture in fishing nets and are hunted almost everywhere they occur. Lucy will speak about her efforts to determine the number of manatee populations across West and Central Africa, to better understand their diet, and to lead the first assessments of manatee threats and the search for solutions across the species’ range.
Tomas Diagne researches threats to sea turtles in Senegal’s coastal waters, which are a migratory hub for five species of sea turtles. In recent years, Tomas has documented a troubling number of dead sea turtles washing up on Senegal’s beaches. Tomas will share how in addition to assessing this disturbing trend, he is working to use the data to advocate for the reduction of sea turtle bycatch in Senegalese fisheries and to collaborate with fisheries authorities to achieve this. He will also speak about his work with sea turtle geneticists to understand from which populations the stranded turtles are coming. Join us to hear Lucy and Tomas share the challenges and successes they have experienced while working to study and protect these iconic and threatened species.

Robo-Shark: How High-Tech Tags Are Revealing the Secret Lives of Sharks
Nick Whitney, Ph.D., Senior Scientist, Anderson Cabot Center for Ocean Life at the New England Aquarium
Have you ever thought about how much your Fitbit® or smartphone tracks your behavior and wondered if scientists could use the same technology to study wild animals? Well they do. Dr. Nick Whitney has applied this technology to study sharks off the coasts of Hawaii, Florida, and Cape Cod. This new technology goes beyond the traditional goal of tracking sharks and begins to reveal what they do. Like your Fitbit, these tags can provide clues about how much energy sharks use in the wild, critical information for understanding their impact on the ecosystem.
Dr. Whitney will speak about his research, including fine-scale information on how sharks swim, rest, mate, and die. He will also explain some of the unique challenges that come with using these tags on sharks, as well as how this technology is providing crucial information for managing shark fisheries. Please join us for an exciting evening of learning about the secret lives of sharks.
Sharks – From Shadow to Light
Brian Skerry, National Geographic photographer and New England Aquarium Explorer-in-Residence
Brian Skerry saw his first shark in the wild in 1982 and was instantly captivated. Over several decades, he has spent countless hours underwater in locations around the world photographing these fascinating animals.
In 2016, National Geographic Magazine published Brian’s stories about sharks in three consecutive monthly issues–June (Tiger Sharks), July (Great White Sharks), and August (Oceanic Whitetip Sharks). In July 2017, his fourth in this series, Shortfin Mako Sharks, will be published.
In the June 1 presentation, Brian will share his personal journey with sharks, from the ways they inspire him to his approach with photography and what he has learned along the way.
Seeing Deeper into the World of the Great White Shark
Greg Skomal, Ph.D., Senior Scientist, Massachusetts Division of Marine Fisheries
Despite its well-established presence in the North Atlantic Ocean, the white shark is not considered an abundant species, and efforts to study its ecology have historically been hampered by the inability of researchers to predictably find these sharks. However, the rebounding population of gray seals off the coast of New England is drawing white sharks in greater numbers to our shoreline. Cape Cod has now become the only known aggregating site for white sharks in the North Atlantic. To take advantage of this opportunity, the Massachusetts Division of Marine Fisheries initiated a long-term white shark research program in 2009 to study the ecology and natural history of this species in the western North Atlantic. With more than 100 white sharks now tagged with sophisticated technology, Greg Skomal and his team are piecing together an incredible story of how this shark lives in the North Atlantic.
Diving Deep: How Do Seals Protect Their Hearts and Brains Without Oxygen?
Allyson Hindle, Ph.D., Assistant Professor, Department of Anesthesia, Massachusetts General Hospital/Harvard Medical School
Manu Buys, Ph.D., Associate Professor, Departments of Anesthesia and Ophthalmology, Massachusetts General Hospital/Harvard Medical School
Seals dive deep into the ocean to hunt while holding their breath. To do this, their physiology is highly specialized compared to other mammals; the hearts and brains of seals are protected from hypoxic injury that would be detrimental to terrestrial species, including humans. To learn about some of the most extreme, deepest diving seals in the world, a research team traveled to McMurdo Station, Antarctica, and tracked down the southernmost mammal on the planet. Join Drs. Allyson Hindle and Manu Buys from Massachusetts General Hospital in discovering what Weddell seals can teach us about new possibilities to treat heart attack and stroke, as well as their own physiological limits in a changing habitat. Science artist Maris Wicks will be a special guest.
Amazing Aquatic Athletes in the Anthropocene
Jodie Rummer, Ph.D, Associate Professor, Australian Research Council (ARC) Centre of Excellence for Coral Reef Studies, James Cook University
Globally, coral reefs are at risk from human-induced stressors – such as ocean warming, acidification, and hypoxia – now more than at any time in recorded history. Dramatic effects on fish performance, distribution, and overall ecosystem health are predicted. While the evolutionary success of fish is credited to their adaptations to challenging environmental conditions, whether they can keep pace with the large-scale, rapid changes plaguing their habitats today is not known. Coral reef fishes may be at greater risk as they diversified during a time of relative stable environmental conditions, and today’s rapidly changing conditions may heighten their vulnerability.
Through her research, Dr. Jodie Rummer is tracking metabolic and swimming performance of fishes under climate-change relevant conditions, across development and species, and over multiple generations. This information is crucial for making predictions as to which species and/or populations may be most at risk from climate change and whether the fishes’ long evolutionary history will be enough to protect them from future changes in their habitat.
A Stroll through the Northeast Canyons and Seamounts Marine National Monument
Peter Auster, Ph.D., Senior Research Scientist, Mystic Aquarium, and Research Professor Emeritus of Marine Sciences, University of Connecticut
Scott Kraus, Ph.D., Vice President of Research, Anderson Cabot Center for Ocean Life at the New England Aquarium
The Northeast Canyons and Seamounts Marine National Monument, which was designated by President Barack Obama on September 15, 2016, is the only marine national monument in the U.S. Atlantic Ocean and the only one located off the continental United States. With words and pictures, Drs. Scott Kraus and Peter Auster will recount their many years of research on marine mammals and deep-sea ecology in this region beyond the edge of our continental shelf. The research was gathered using ships, aircraft, and deep-sea submersibles.
Beach Babies – White Shark Nurseries of the Northeast Pacific
Christopher G. Lowe, Ph.D., Professor of Marine Biology, California State University Long Beach
Coastal waters can be important feeding grounds for white sharks, particularly areas with high densities of seals and sea lions. In addition, female white sharks also visit coastal waters to give birth to their young. Baby and juvenile white sharks have been found to use shallow open beach habitats and bays as nurseries. So, what does a white shark nursery look like? Probably like your favorite beach. And, why are they there? Probably for the same reasons you are; it’s safe in shallow waters, there is plenty of easy-to-obtain food (not to worry, that doesn’t include you), and it’s warm! Just like any summer beachgoer, baby white sharks don’t like the cold, so they quickly migrate to warmer waters, following the coastline when the temperature drops. We’ve learned all this using a variety of new technology such as acoustic and satellite transmitters, autonomous underwater and aerial vehicles (spybots), and underwater camera (selfie) stations. We’ve even learned about how El Niño can change their migration behavior and how that effects public perception of sharks. Come learn what we think makes for a good white shark nursery and where we might predict the next ones to pop up.
Sharks in Our Backyard: The Resurgence of Sand Tiger Sharks in New England
Jeff Kneebone, Ph.D., Associate Research Scientist, Anderson Cabot Center for Ocean Life, New England Aquarium
Despite their scary appearance, sand tiger sharks are docile ocean animals that pose no real threat to humans. Although it has a rich history in New England, this species has declined due to threats like overfishing, and was rarely observed in our region during recent decades. However, a significant number of juvenile sand tigers returned to local waters in the last five to 10 years. Come learn about the biology, conservation, and fascinating resurgence of this species in our own backyard.
Sharks in Danger: Silver Fins and a Silver Lining?
Mark Smith, Vice President of Animal Care, New England Aquarium
John Mandelman, Ph.D, Vice President, Anderson Cabot Center for Ocean Life, New England Aquarium
Shark! We hear the word, and our senses heighten with fear-inducing images of scything fins and serrated teeth. But what is the truth about these frequently vilified denizens of the deep? Join New England Aquarium scientists Mark Smith and John Mandelman for a deeper look at the shark: their cultural impact, their diversity and biology, and, in the context of marine conservation and human interactions, how we should be terming it “shark attacked” rather than “shark attack.”
Finally, learn more about some of the amazing scientific and tireless advocacy work fighting to counteract the mounting conservation threats facing these majestic animals around the globe, as well as a preview of shark-related offerings in the spring lecture series, and work out of the Aquarium’s new Anderson Cabot Center for Ocean Life.
A Clam’s-Eye View of Climate Change: How Do Intertidal Organisms Experience Their Shifting World?
Brian Helmuth, Ph.D., Professor, Northeastern University Marine Science Cent
The impacts of global climate change on ocean ecosystems are now pervasive. But how well do we truly understand the ways in which a shifting climate affects nonhuman organisms, and how might our anthropocentric view of the world cloud our understanding of what to expect in nature? For example, the vast majority of plants and animals, unlike humans, make no metabolic heat and, as such, they have body temperatures that can fluctuate by 30 degrees Fahrenheit or more over the course of a few hours.
Using a unique combination of computer modeling, field instrumentation, and virtual reality technology, Brian Helmuth gives a worldwide tour of how climate change is affecting coastal ecosystems from the perspective of marine invertebrates and explores how many of the most significant effects of global climate change can only be predicted when we step outside our biased perceptions of how weather and climate affect natural ecosystems. His results suggest that while many coastal ecosystems may be much closer to collapse than initially expected, in some cases, climate change can lead to positive responses at some locations. Discerning among these possibilities is therefore crucial if we are to find novel ways of adapting to a warmer planet.
Invasive Species and Carbon Cycling in Coastal Dunes of Cape Cod
Robert Vincent, Ph.D., Massachusetts Institute of Technology, Sea Grant College Program and
Rose M. Martin, Ph.D., Oak Ridge Institute for Science and Education, Postdoctoral Researcher at EPA Atlantic Ecology Division
The MIT Sea Grant College Program and the U.S. Environmental Protection Agency have been working with the National Park Service to study carbon cycling in coastal dune habitats, as well as the effects of historic peat deposits on the establishment and persistence of invasive plants (Phragmites australis). With the increased risk of erosion from coastal storms exposing the once-buried peat deposits, and the challenge of controlling an aggressive invasive species, this dynamic system faces an uncertain future. The research findings from this study will inform future conservation efforts in the region as well as provide a deeper understanding of carbon cycling in coastal dunes.
The Conservation of Devil Rays
Daniel Fernando; Co-founder of Blue Resources; Associate Director of The Manta Trust; Ph.D. student at Linnaeus University; New England Aquarium Marine Conservation Action Fund Fellow
Devil rays, also known as mobula rays, are closely related to the more iconic and better known manta rays. In recent decades, all these species have been facing increasing threats driven by unsustainable target and bycatch fisheries, seeking to supply the international demand for their dried gill plates in Chinese medicine. Growing awareness and concerns for the survival of these species resulted in some level of international protection. However, further work is required. Daniel Fernando tells us about his research efforts to better understand these animals and about his work to promote their conservation.
Saving Sea Turtles: Preventing Extinction
Michele Gomes and Jennifer Ting – Filmmakers
Panel discussion with:
- Dr. Charles Innis, Director of Animal Health, New England Aquarium
- Constance Merigo, Marine Animal Rescue and Rehabilitation Manager, New England Aquarium
- Bob Prescott, Sanctuary Director of Mass Audubon’s Wellfleet Bay Wildlife Sanctuary, and NOAA’s Mass. (Quincy south) Sea Turtle Stranding Coordinator
- Kate Sampson, Sea Turtle Stranding Coordinator, NOAA Fisheries Greater Atlantic Region (VA through ME)
Late each autumn, hundreds of sea turtles strand on Cape Cod due to hypothermia. For more than 25 years, the New England Aquarium and the Mass Audubon Wellfleet Bay Wildlife Sanctuary have worked together to rescue, rehabilitate, and release thousands of these turtles, mostly Kemp ridleys. Over the last decade, the number of stranded turtles has steadily increased, but the late autumn of 2014 saw an unprecedented event as more than 1,200 cold-stunned sea turtles washed ashore. This massive wildlife emergency marshaled an inspiring response that reached from individuals to the federal government.
Fortunately, two independent filmmakers from Seattle, Michele Gomes and Jenny Ting, were on hand to document this phenomenon. They also traveled to Mexico and Texas to tell the larger natural history story of the world’s most endangered sea turtle and how humans pushed a healthy population to the precipice of extinction and are now slowly helping it to recover. Attendees watched Michele and Jenny’s film, “Saving Sea Turtles: Preventing Extinction,” (watch the trailer) and a panel discussion.
The Sea-Run Fish of Massachusetts
Bradford Chase, Marine Fisheries Biologist, Massachusetts Division of Marine Fisheries
Diadromous, or sea-run fish, have the risky life strategy of leaving the ocean to migrate toward coastal rivers where humans and many types of fish and wildlife predators challenge their quest. Less than one percent of the fish on the planet have adapted to this reproductive life history, but many, such as salmon and eel species, are well known for their high value and cultural importance. Join Bradford as he discusses the diadromous fish of Massachusetts with information on their biology, management, and threats to survival, with a special focus on the iconic river herring and American eel.
Jellyfish: Are They Taking Over?
Lisa-ann Gershwin, Ph.D., Director, Australian Marine Stinger Advisory Services
Author, Jellyfish: A Natural History
Jellyfish! The mere mention of the word sends shivers down the spines of those who have been stung—or don’t want to be. Whereas once only swimmers feared their stings, more and more, it seems, jellyfish are demanding attention in a variety of ways.
Whether they get sucked into the water intake pipes of nuclear power plants and trigger emergency shutdowns, capsize fishing trawlers, kill tourists, or surreptitiously take over ecosystems, reports are drifting in from all the world’s oceans. Join lively and passionate Australian scientist and writer Lisa-ann Gershwin as she explains why we are seeing more jellyfish and what it means for our future.
Fish Blowing Up? Handling Barotrauma in the Gulf of Maine
Matt Ayer, Recreational Fisheries Biologist, Massachusetts Division of Marine Fisheries
Barotrauma is an injury caused by a change in gas pressure. In many fish species, barotrauma occurs when the swim bladder expands or ruptures as fish are brought to the water’s surface. In the recreational groundfish fishery in the Gulf of Maine, there are multiple species that exhibit signs of barotrauma when caught. In some cases, these symptoms can be severe and significantly increase the mortality of discarded fish. One method of increasing the survival of released groundfish is to assist their descent and recompression using a “release device.” Such devices are commonly used in other parts of the country, but have been only recently introduced to Gulf of Maine anglers. Learn from recreational fisheries biologist Matt Ayer about fish filled with air and how anglers may be able to help them.
Epizootic Shell Disease in the American Lobster, Homarus Americanus
Professor of Marine Science, Virginia Institute of Marine Science, The College of William & Mary
Populations of the American lobster, Homarus americanus, off southern New England are threatened by epizootic shell disease (ESD). The disease causes a rapid necrosis of the shell making infected lobsters unmarketable. The disease has negatively affected the fishery, but it has been difficult to quantify its impact on lobster populations. ESD is caused by a shift in the bacterial community (dysbiosis) that occurs in relation to changes in environmental and anthropogenic stressors. Temperature is a key variable in ESD but its effect has not been well characterized.
Join Jeff Shields as he discusses environmental diseases in lobsters and what can be done about them. He will present an overview of the disease and give new findings on his recent studies. He will also address aspects of the dysbiosis, the effect of temperature on individuals and projected effects on populations, as well as new insights into the epidemiology of the disease. Understanding the complex interplay among temperature, disease dynamics, and lobsters is critical for assessing the risk of expansion of the disease into the Gulf of Maine.
Stress in Wild Animals: From the Arctic to the Equator
L. Michael Romero, Ph.D.
Professor of Biology, Tufts University
In contrast to stress-related disease in humans, the stress response is vital for helping wild animals survive in their natural habitats. The hormonal and physiological responses to stress are similar in all vertebrates. When these systems are activated at the wrong times for the wrong durations, disease can result. However, these same systems allow wild animals to survive natural stressors such as storms, predation attempts, and starvation. Join professor Michael Romero as he presents highlights from more than 25 years of research on stress in wild animals. Furthermore, he will discuss how understanding the stress response may also show us how animals cope with human-created changes in their habitats.
Lessons from the Gulf of Maine on How to Live in a Warmer World
Andrew J. Pershing
Chief Scientific Officer, Gulf of Maine Research Institute
Waters all over the world are warming. However, due to its unique oceanography, the Gulf of Maine is one of the fastest warming regions of the global ocean. The warming of the waters off New England has led to declines in important commercial species such as northern shrimp and cod, but it is also creating new opportunities as warmer-water species move northward. Join Dr. Pershing to hear how the rapid warming in the Gulf of Maine gives us a unique opportunity to understand how ocean animals respond to changes in temperature and how we can prepare for the changes that we know are coming.
Big Ice: Antarctica, Greenland, and Boston
Sixth Annual John H. Carlson Lecture Presented by MIT’s Lorenz Center and the New England Aquarium
Dr. Richard Alley
Evan Pugh Professor of Geosciences at Penn State’s College of Earth and Mineral Sciences
An ice sheet is a two-mile-thick, continent-wide pile of old snow, spreading under its own weight and sculpting the land beneath. The ice sheet that buried Boston 20,000 years ago melted when slowly acting features of Earth’s orbit raised summer sunshine and atmospheric carbon dioxide, warming the climate. The history of that ice Age can still be read in Boston Harbor and in the layers of the surviving ice sheets on Antarctica and Greenland. Join Dr. Richard Alley to learn how more warming may melt those ice records, as break-off of huge icebergs and outburst floods speed sea-level rise.
Pioneering Manta Ray and Community-Based Conservation in Peru
Founder and Director, Planeta Océano, Marine Conservation Action Fund Fellow*
One of the world’s largest populations of giant manta rays migrates into the waters off of Peru. However, mantas in Peru had been severely overlooked and were exposed to unregulated fisheries. Since 2012, Kerstin Forsberg has been leading initiatives to pioneer manta ray conservation in Peru in partnership with local fishing communities and international organizations. Her team’s comprehensive efforts have included researching manta harvest and occurrence, building local awareness, and engaging artisanal fishermen in community-based manta eco-tourism. Building upon this work, and after two years working with the Peruvian government, Forsberg led the effort to secure full legal protection for manta rays in Peru. Join Kerstin Forsberg as she shares the story of her groundbreaking work with mantas, and describes how her organization, Planeta Océano, is growing into a model for community-based conservation.

Rigs to Reefs: A Blue Solution to Repurpose the World’s Offshore Oil and Gas Platforms
Emily Callahan and Amber Jackson, Co-Founders of Blue Latitudes
There comes a time when the useful life of an oil platform comes to an end, at least when it comes to drilling for oil, and that’s when Emily Callahan and Amber Jackson, co-founders of Blue Latitudes, dive in. They are marine scientists on a mission to re-purpose offshore oil and gas platforms as artificial reefs around the world. The oil platforms found in their home state of California, like most offshore oil platforms around the world, are home to some of the most productive ecosystems on the planet. As the world’s natural reefs are overfished, over-trawled and polluted, Amber and Emily believe that re-purposing these structures, some the size of the empire state building, as artificial reefs, may be the best decision for the future of our oceans. It’s time to think creatively about the resources we have, and proceed forward boldly with radical new tactics for ocean management. Join Callahan and Jackson to hear how Rig2Reef Exploration has successfully conducted research expeditions in the North Sea, Gulf of Mexico and California, investigating the ecological, economic and cultural benefits of re-purposing these offshore platforms in a variety of ways, from eco-tourism hot spots, to national marine sanctuaries.
Can We Save Coral Reefs and If So How?
Jeremy Jackson, Professor of Oceanography Emeritus at the Scripps Institution of Oceanography and Senior Scientist Emeritus at the Smithsonian Institution
Reef corals are declining worldwide. Climate change dominates the headlines, especially in relation to the recent mass bleaching and death of corals along the northern Great Barrier Reef and throughout the Pacific. But climate change is only half of the story. Up to now, the destructive impacts of climate change on reefs have been much less than the localized effects of overfishing, land-based pollution, and loss of habitats due to coastal development. A recent study of changes on Caribbean reefs over the past 50 years demonstrates that reefs with effective local protections and governance have double the amount of living coral, more fish, and clearer waters than reefs without protections. These new findings show that there are things we can do right now to help reefs recover. We need to stop all forms of overfishing, establish very large marine protected areas, and impose strict regulations on coastal development and pollution while at the same time working to reduce the use of fossil fuels. It’s not either/or, but all of the above.
Searching for Sea Monsters
Dr. Ruth Leeney, Marine Conservation Action Fund Fellow, Sawfish Conservation Officer for the IUCN Shark Specialist Group, Post-doctoral Research Fellow at Simon Fraser University, and Director, Protect Africa’s Sawfishes
Sawfishes are some of the most unique and bizarre-looking of all aquatic animals. They are also the family of elasmobranchs (sharks and rays) most threatened with extinction. One of the major constraints to protecting the few remaining populations of sawfishes worldwide is that there is remarkably little information available on where sawfishes can still be found. Since 2012, Ruth Leeney has conducted baseline data on sawfishes in eight countries through her organisation Protect Africa’s Sawfishes, to help identify where conservation and research efforts for sawfishes should be focused. Ruth will share some of her findings from recent research projects, as well as the highs and lows of travelling and working in some fascinating and hard-to-reach regions.
The Impact of Invasive Lionfish on Bermuda’s Marine Ecosystem
Corey Eddy, Ph.D. Candidate, University of Massachusetts Dartmouth
Lionfish have become the poster animal for invasive species, and they fit the definition perfectly; they were introduced by humans to the Atlantic Ocean, where they do not belong and could potentially cause significant environmental harm, possibly decimating entire ecosystems. Naturally found in the Indo-Pacific, they were first reported off the Florida coast in the 1980s, and in less than 30 years spread throughout the entire northwestern Atlantic.
Join us to hear from a local researcher about his study of their potential impact on Bermuda’s coral reef ecosystem. You’ll learn how their biology and ecology make them an incredibly successful predator and why we are so concerned with this invasion.
Harvesting Fish for Aquariums: How Many Is Too Many?
Dr. Michael Tlusty, Director of Ocean Sustainability Science, New England Aquarium,
Dr. Andrew Rhyne, Assistant Professor, Roger Williams University and Research Scientist, New England Aquarium, and Ret Talbot, Host of the Fisheriescentric blog www.GoodCatchBlog.com
Each year, millions of fish are collected from reefs to place on exhibit in homes and public aquariums. It was only recently that New England Aquarium staff have figured out a way to collect data on the numbers and species of fish involved in the marine wildlife trade. Join our speakers to understand the diversity of this marine trade, and how the volume of the trade can be calculated. They will also discuss how the data can better inform the management of the marine species, and why these fisheries are important to small reef-side economies. Finally, they will describe the role of aquaculture as an aid to this trade and how the Aquarium is leading the effort to use public aquariums as a new source of fish for exhibits.
Diagnosing Leviathan: Adventures of a Whale Veterinarian*
Rosalind M. Rolland, DVM, Director of Ocean Health and Senior Scientist, New England Aquarium
In the late 1990s, the number of calves born to highly endangered North Atlantic right whales plummeted, declining to only 1 calf in 2000. Seeking to understand why right whales were not having more calves, Dr. Rosalind “Roz” Rolland, a research veterinarian, developed a variety of new ways to study health and reproduction in 50-ton whales in the wild. Over the past 15 years, Dr. Rolland has pioneered methods to measure an array of hormones in whales using novel samples including feces, respiratory vapor, and baleen. She oversaw the creation of an approach to monitor whale health using photographs, and studied red tides and disease. Her research has led to many adventures including an expedition to the sub-Antarctic Auckland Islands, and training as a scent detection dog handler.
Dr. Rolland will be presenting her work on whale health and what whales tell us about ocean health, including some of her adventures along the way. Following the lecture, Dr. Rolland will be signing copies of the book she co-edited on right whales, The Urban Whale: North Atlantic Right Whales at the Crossroads.
Real Mermaids: Dugongs in Australia
Elizabeth Burgess, Postdoctoral Researcher, New England Aquarium
Christopher Columbus believed he was looking at a mermaid when he saw his first manatee. However, it is the dugong that is the more likely suspect of most mermaid stories. Closely related to portly manatees, the dugong is an unusual marine mammal. It has a vast global range that spans the Indo-Pacific region, but it relies on inshore habitats, which places it in close proximity to humans — and their associated impacts.
Elizabeth Burgess will take you on a trip to Australia — the dugong’s last stronghold. She will focus on the need to obtain vital reproductive information on populations surviving along a heavily impacted urban coastline. Dugongs are notoriously difficult to study; dugong research in the past had been obtained through carcass analysis from incidental drownings and indigenous harvests. The research that Elizabeth will present took on the challenge of using a hands-on approach to study live dugongs, which has allowed for a better understanding of pregnancy, seasonality, reproductive strategies and stress responses in a free-ranging population. Join us for a talk on this unique marine species, and novel research approaches.
The Phoenix Islands Protected Area: X Marks the Spot
2015 Expedition Team: Randi Rotjan, PhD, Associate Research Scientist; Julie Cavin, DVM, Associate Veterinarian; and Peter Gawne, Senior Aquarist, New England Aquarium
The Phoenix Islands Protected Area is the largest and deepest World Heritage Site on earth, and it is located in the Central Pacific, where the international dateline meets the equator (X marks the spot). The New England Aquarium has been involved with this special place since 2000, and a 2015 expedition conducted research on climate change and the current El Niño, the impacts of old shipwrecks on coral reefs, and the health of shark populations (among other things). Come hear a subset of expedition members tell their tale of time spent on the high seas, and their adventures (and findings) from one of the most remote reefs on the planet.
Ocean Country: Hope for the Seas*
Liz Cunningham, author and environmental activist
*Book signing to follow
Ocean Country, by Liz Cunningham, with a foreword by Carl Safina, is an adventure story and a meditation on the state of the seas. Most of all it is the story of finding true hope in the midst of urgent environmental crises.
After a near-drowning accident in which she was temporarily paralyzed, Liz Cunningham crisscrosses the globe in an effort to understand the threats to our endangered oceans. This intimate account charts her thrilling journey through unexpected encounters with conservationists, fishermen, sea nomads, and scientists, in the Mediterranean, Sulawesi, the Turks and Caicos Islands, and Papua, New Guinea. Join us to hear Cunningham share stories and photographs about the amazing people she met, who showed her what true hope can be.
Twenty-one percent of royalties from Ocean Country are being donated to the New England Aquarium’s Marine Conservation Action Fund (MCAF), which funds small-scale conservation projects around the world – from protecting manta rays in Peru to saving sea turtles in Florida and Costa Rica. MCAF Manager, Elizabeth Stephenson, will also share remarkable stories of hope for the oceans that have been catalyzed by this long-standing micro-funding program.
Climate Ready Boston
Bud Ris, Senior Advisor on Climate Change, Barr Foundation, Green Ribbon Commission
Boston faces significant challenges from the impacts of climate change. Former New England Aquarium President and CEO, Bud Ris will review newly updated projections for the impacts anticipated over the next several decades and discuss a major project the city has launched to begin planning for these changes. Anyone living or working in the city or concerned about the future of Boston’s waterfront will benefit from this informative session.
The Mystery of Whale Eyesight and (Big) Things that Go Bump in the Night
Dr. Scott Kraus, Vice President of Research, New England Aquarium
Both right and humpback whales get entangled in fishing gear along the east coast of the U.S. at rates that are unsustainable for these endangered species. Failure to solve this problem may jeopardize the viability of several fisheries. Dr. Kraus and his team set out to study why whales don’t see ropes and avoid them. Then they wondered if ropes can be developed that provide whales a visual deterrent, thereby averting entanglements. In addition, they knew that most knowledge about whale behavior is primarily derived from daylight observations. Since most terrestrial mammals exhibit diurnal changes in behavior, it is reasonable to expect changes in whale behavior at night. Do those changes put whales at risk of encounters with fishing gear? The questions then multiplied! Do they see color? Can they see at night or in the darkest depths of the ocean? How small an object can they see?
Whales live in a world where visibility is rarely more than 40 feet, and most people believe they find their way around by sound. In fact, their use of sound is critical, but for close-up interactions with neighbors, feeding, and collision avoidance, vision may be even more important. Over the last five years, we have been doing field and laboratory experiments to develop an understanding of what whales see. Join Dr. Kraus to find out how their findings may help reduce fatal entanglements by large whales in fishing gear.
The Ocean’s Most Spectacular Color Change Artists
Roger T. Hanlon, Ph.D., Senior Scientist, Marine Biological Laboratory, Woods Hole and Professor, Ecology and Evolutionary Biology, Brown University
Nature has evolved elegant solutions for manipulating ambient light to create patterns and coloration for a wide range of functions, such as communication and camouflage. Nowhere is the diversity and speed of change in color patterning better developed than in the cephalopods (squid, octopus, cuttlefish). Using high-definition video and still photography, Dr. Roger Hanlon will illustrate the beauty and complexity of skin patterns that cephalopods and fishes use throughout the world’s oceans.
Dr. Hanlon will introduce the audience to “rapid adaptive coloration” and some gorgeous details of the skin of these animals – a rich array of pigments and reflectors that will make any artist envious. In that context, he works together with artists to try to understand how patterns and colors create such optical illusions that enable the soft-bodied cephalopods to deceive the visual capabilities of their many fish, bird, and marine mammal predators. Throughout this presentation, he will emphasize the complex and often extravagant behaviors of these amazing oceanic animals.
Pingers, Spools, and Crooked Hooks: Modifying Fishing Practices to Prevent Marine Extinctions
Timothy B. Werner, Senior Scientist and Director of the Consortium for Wildlife Bycatch Reduction, John H. Prescott Marine Laboratory, New England Aquarium
Demand for seafood is emptying the sea of its most iconic and ecologically important animals, including whales, dolphins, porpoises, seabirds, sea turtles, sharks, and corals. The nets, hooks, ropes, traps, and pots that fishermen use to capture their target catch also injure and kill these other animals in the hundreds of thousands every year. As a consequence, many of these species are being depleted to such low abundances that they face premature extinction, and no longer provide critically important ecosystem services.
While closing parts of the ocean to fishing can help mitigate the problem, it is only part of the solution. The Consortium for Wildlife Bycatch Reduction, a unique collaborative research program between fishermen and scientists based at the New England Aquarium, has been retooling fishing techniques; discovering new ways to fish that can reduce the bycatch of endangered marine species. From the northern U.S. to the tropical Pacific and Patagonian seas, Werner will share examples of our cooperative research to modify fishing gear and practices, and highlight the challenges we must overcome to eliminate the most immediate threat to many endangered marine species worldwide.
Movie Premiere: Sonic Sea
Followed by a panel discussion and Q&A with:
Michael Jasny, Director, Marine Mammal Protection, Natural Resources Defense Council
Brandon Southall, Senior Scientist, Southall Environmental Associates, Inc.
Scott Kraus, Vice President of Research, New England Aquarium
Chris Clark, Johnson Senior Scientist, Bioacoustics Research Program, Cornell University
Patrick Ramage, Program Director, Whales, International Fund for Animal Welfare
Moderated by Leila Hatch, Ph.D., Marine Ecologist, Office of National Marine Sanctuaries, NOAA
The ocean is not a silent world, but a dynamic, living symphony of sound. In water, sound travels five times faster and many times farther than it does in air. Whales, dolphins, porpoises and other marine mammals have evolved to take advantage of this perfect sonic medium. Just as we rely on sight to survive, they depend on sound to hunt for food, find mates, and detect predators.
Over the last 50 years, our increasing ocean presence has drastically transformed the acoustic environment of these majestic creatures. Undersea noise pollution is invisible but it is damaging the web of ocean life.
Sonic Sea is about understanding and protecting the vast symphony of life in our waters.
Using Technology to Save the World
Shah Selbe, Conservation Technologist, National Geographic Society Explorer and Marine Conservation Action Fund Fellow *
Earth is currently in the midst of the sixth mass extinction, where poaching, overfishing, and habitat destruction are driving wildlife populations to critically low levels. Conservation needs better methods to help mitigate the effects of climate change and human impact. Thankfully, we are living in age where technology has improved nearly everything we deal with on a daily basis. Shah Selbe has, through his work as a National Geographic Explorer, developed innovative conservation technologies to deal with protecting wildlife and protected areas globally. This work has taken him from the beaches of Palau, wetlands of Botswana, mangroves on Caribbean islands.
Hear Selbe tell stories of using drones, satellites, and the Internet of Earth Things (focused on connecting ecosystems using the same technology as “smart homes”) to help stop wildlife crime and ensure a future full of iconic animals like elephants, bluefin tuna, and tigers.
