Invasive Species and Carbon Cycling in Coastal Dunes of Cape Cod
Thursday, March 30
Robert Vincent, Ph.D., Massachusetts Institute of Technology, Sea Grant College Program
Rose M. Martin, Ph.D., Oak Ridge Institute for Science and Education, Postdoctoral Researcher at EPA Atlantic Ecology Division (pictured)
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.
A Clam’s-Eye View of Climate Change: How Do Intertidal Organisms Experience Their Shifting World?
Thursday, April 6
Brian Helmuth, Ph.D., Professor, Northeastern University Marine Science Center
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.

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.
Sharks in Our Backyard: The Resurgence of Sand Tiger Sharks in New England
Thursday, April 20
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.
Beach Babies – White Shark Nurseries of the Northeast Pacific
Tuesday, April 25
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.
A Stroll through the New Northeast Canyons and Seamounts Marine National Monument
Thursday, May 4
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 gathered using ships, aircraft, and deep-sea submersibles.
Amazing Aquatic Athletes in the Anthropocene
Thursday, May 11
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.
Diving Deep: How Do Seals Protect Their Hearts and Brains Without Oxygen?
Tuesday, May 16
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.
Seeing Deeper into the World of the Great White Shark
Thursday, May 25
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.
Sharks – From Shadow to Light
Thursday, June 1
Brian Skerry, New England Aquarium Explorer-in-Residence and National Geographic photographer
Brian Skerry saw his first shark in the wild in 1982 and was captivated. Over the last three and a half decades he has spent countless hours underwater in locations worldwide photographing these enigmatic 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 o his approach with photography and what he has learned along the way.
Robo-Shark: How High-Tech Tags Are Revealing the Secret Lives of Sharks
Thursday, June 8
Nick Whitney, Ph.D., Senior Scientist, Anderson Cabot Center for Ocean Life, 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.
