#15: Mavynne entangled and freed

Mavynne, #1151, is a mom this year. She and her calf were seen by our team for the first time this season on August 28, up off the Wolves. Apparently the pair did not stay in the Bay of Fundy for long as Mavynne was found severely entangled on September 4, on Jeffrey's Ledge, 25 miles off the coast of New Hampshire.



Fortunately our colleagues from the Provincetown Center for Coastal Studies who specialize in large whale disentanglement were able to respond and remove all the gear from Mavynne. No one has seen her since that time and we don't if she and her calf are still together. You can search for sighting histories and photos of Mavynn (#1151) on the North Atlantic Right Whale Catalog.

#5: Two Seriously Scarred Whales Show Signs of Previous Entanglements

Part of the work we do at the New England Aquarium is to figure out how frequently right whales get scars from entanglements and vessel strikes. All images of each individual right whale are carefully reviewed to look for subtle and not so subtle evidence of these and to determine the time frame in which the interaction must have occurred. (Click photos to enlarge.)














The findings of this longterm scar coding study are provided to NOAA Fisheries Service (who supports the scar coding work) on a regular basis to help inform their management efforts aimed at reducing the frequency and severity of these events. NOAA Fisheries has implemented numerous measures in U.S. waters over the years for how, when and where fishermen set and configure their fixed fishing gear based on knowledge of right whale distribution and the types of gear found on right whales and other large whale species. For more details about these measures, visit the NOAA Whale Take Reduction Plan.

Over the 6 days at sea so far in the Bay of Fundy, we have seen two animals with severe entanglement scarring. The first animal and the one of most concern to us is Baldy's 2009 calf (Eg # 1240). The pair was seen together on August 9. We were so excited to see that Baldy and her calf had made the long migration from the southeast U.S. calving grounds to the Bay of Fundy. Baldy is one of the older known reproductive females in this population and she has given birth to 8 calves from 1974 to the present. (see our previous post about Baldy's story).

Our excitement upon finding the pair was quickly tempered when we saw major entanglement wounds on the tail stock of the calf--deep cuts into the leading edge of the fluke and peduncle. These are the sort of injuries that make you cringe to think of the pain this calf obviously endured and how hard it must have struggled to break free of the entangling line. The pictures of this calf's wounds speak for themselves, showing gruesome evidence of the problem these animals face. The overall condition of the calf is clearly compromised and its skin towards the aft part of its body looks grey and is peeling significantly, and the tail and body are partially covered by orange cyamids which also can be indicative of poor health.

We are very concerned about the prognosis for this calf. If we see them again this season, we will collect and compare photographs to this initial sighting to see if the calf's condition has changed. Hopefully this little one can survive this ordeal.

The second animal with serious scarring was seen on August 16. Although we have not yet matched it to the catalog, it appears to be a yearling. The tail region has many raw, wrapping scars indicative of a fairly recent entanglement interaction. This animal will likely survive this ordeal but the stress caused by the struggle to break free of the gear and the resulting injuries could be compromising this animals' long term health.

The solution to eliminating or reducing such severe entanglements remains elusive. But we continue to monitor the occurrence of these events, provide this information to the federal government, and constantly work towards finding solutions that will protect the whales and allow fishermen to fish.

#4: 3 Days Straight on the Water!

August is proving to be a great month for surveys. We were able to get out the past three days! The winds were light Wednesday and Thursday and sighting conditions were excellent for surveying the bay. Conditions Friday were not as nice; the sea was calm in the morning, but quickly picked up early in the afternoon. Luckily, we were close to home when the weather turned sour. The ride home through the Grand Manan Channel was wet, but short and we made it to the dock at 2:30 p.m.

The Bay was as calm as a lake both Wednesday and Thursday. At one point Amy took a picture of her reflection in the water while the boat was moving. Such calm conditions allowed us to cover a good portion of the bay. We surveyed the southern part of the bay as far east as the shipping lanes.

On Wednesday, we sighted a lot of right whales near the shipping lanes and noticed an oil tanker in the outbound shipping lane. Moe radioed Fundy Traffic and notified them of the presence of right whales in the area. Fundy Traffic responded immediately, notifying the oil tanker of the whales position. We were all very pleased with how quickly Fundy Traffic responded.

There seems to be a lot of activity in the bay this year. Thursday, we sighted 14 humpback whales, 27 right whales and 407 harbor porpoises! That's quite an improvement compared to the 2 right whales we saw on our first day out. To date, we have sighted 33 individual right whales, which includes 7 of the 39 mother and calf pairs seen in the southeast calving grounds this past winter.




The weather is marginal for the next couple of days. We are watching the weather forecasts closely and hoping for the winds to drop low enough for us to get out on the water.

Stay tuned for more posts about who we've sighted and more exciting stories of our adventures in the Bay of Fundy!

#34: Success at last!


We are extremely pleased to report that the Final Rule (pdf) to implement Operational Measures of the North Atlantic Right Whale Ship Strike Reduction Strategy has passed the final hurdle in the rulemaking process and will be published in the Federal Register tomorrow, October 10.

The rule will go into effect in 60 days--early December--just in time for the start of the winter calving season in the southeast United States. The crux of these measures will be the requirement to slow ships to 10 knots or less within 20 nautical miles of port entrances and in other major right whale habitats.

Despite the fact that it is not as strong as initially proposed due to political wranglings, which I covered in an earlier post, it is a monumental and unprecedented step towards reducing the possibility of vessel strikes of right whales and other large whales living in our near shore waters. We applaud NMFS for pushing this rule forward despite heavy opposition from the administration and the shipping industry. The science is strong and the need is great to give these endangered whales a safer haven. For more details about the rule, visit the NOAA shipstrike page.

#21: Protecting right whales from ship strikes in the U.S. - one step closer?



Right whales have been in the news in the past week - The Washington Post, Cape Cod Times, New York Times, National Geographic News to name a few have picked up the story that on Monday, August 25, the National Marine Fisheries Service (NMFS) filed their Final Environmental Impact Statement (FEIS) for the Ship Strike Reduction rule.

What does this all mean? Well, for many years (nearly a decade), the New England Aquarium, members of the shipping industry, maritime law experts, conservation groups, and the federal government (NMFS) have been working to formulate a strategy to reduce the level of vessel strikes of right whales, the leading known cause of mortality for this small population.

In 2001, a suite of recommended measures was submitted to NMFS after years of useful dialog within this group. NMFS conducted further analyses on economic impacts, as well as all other possible options that could be considered, and initiated a rulemaking process to implement several measures including speed restrictions of 10 knots or less along the eastern U.S. seaboard within 30 nautical miles (nm) of port entrances for all vessels over 65 feet in length.

This aspect of the federal rulemaking process started in June 2004 with an Advanced Notice of Proposed Rulemaking. A Proposed Rule was published in June 2006 and a Final Rule was submitted to the Office of Management and Budget for their approval in February 2007, a process that typically takes 90 days. It has now been more than 540 days.

The longer-than-usual process has not been without hurdles and frustrations along the way, further complicated by political meddling and a twisting of the democratic process. This fact was most recently captured in by articles in the Washington Post and the Cape Cod Times. As a result of this meddling by Vice President Cheney's office and strong opposition from the World Shipping Council, the Office of Management and Budget stalled the rulemaking process for a year and a half.

In order for anything to move forward, NMFS had to back off from their initial intent and reduce the 30-mile buffer to 20 miles--a significant reduction in protection for right whales.

Yet, this watered down rule will still mean more protection to right whales than no rule at all. So we are cautiously optimistic that the process will continue without additional delays. The FEIS has a 30-day comment period after which a Final Rule can be promulgated. Implementation of the Final Rule then occurs 60 days after it is filed however no one knows how long it might take for this last step to happen.

Right whales are at a critical junction. The level of reproduction has increased over the last 8 years, so the whales are doing their part. It is essential that the youngsters are given the space the mature and reproduce. Measures to reduce ship strikes have been implemented in the portion of their summer and fall range that includes habitats in eastern Canada.

Implementation of the Final Rule in US waters means that right whales will have greater protection from vessel strikes throughout their range along the eastern seaboard of the U.S. and Canada. If the U.S. measure is implemented, right whales may be able to migrate along the urbanized U.S. coastline this winter en route to their calving ground off the southeast U.S. coast in greater safety than they have ever experienced in their lives. That would be a monumental step forward for this struggling species. Stay tuned as this story unfolds over the next several months!

Please consider submitting comments on the Final Environmental Impact Statement. You can find the information you need on the NMFS ship strike page.
