Right whale death off Virginia coast adds to concern about species’ demise

January 30, 2018 — The death of a right whale, spotted floating off the Virginia Beach coast last week, has drawn wide attention to a species considered one of the most imperiled of marine mammals.

The 10-year-old juvenile female is believed to have become entangled in fishing gear, and its death was the first of 2018 among North Atlantic right whales. The 39-foot whale was buried at Sandbridge’s Little Island Park beach after a necropsy Sunday involving experts from six institutions from Massachusetts to Florida.

Only about 450 of the whales are believed to exist after at least 17 deaths last year, and so far this winter no newborns have been spotted in the calving grounds off Florida and Georgia.

That has added to concern that the species’ demise might be accelerating. Some scientists have predicted that North Atlantic right whales could become extinct this century.

Earlier this month, the Center for Biological Diversity and two animal welfare groups sued the National Oceanic and Atmospheric Administration and its parent agency, claiming that they’re not enforcing laws and regulations meant to protect the whales from entanglement in lines for lobster traps and other fishing gear.

Jennifer Goebel, a spokeswoman for NOAA Fisheries, said the whale found dead near the North Carolina border was wrapped in line in a way that suggested it had been alive when it encountered the gear. She said officials will try to identify the line and who had deployed it.

Fishing Gear Deaths, Low Birth Rate Tell Grave Tale for Right Whales

January 26, 2018 — About 25 North Atlantic right whales gathered south of the Vineyard this week, marking an early-season sighting of a species that scientists warn could go extinct in the next 20 years.

The sighting belies the plight of the species, Dr. Mark Baumgartner told a crowd of about 50 people gathered in the Gazette newsroom Tuesday for a talk. There are an estimated 450 whales left.

Mr. Baumgartner, a scientist with Woods Hole Oceanographic Institution and president of the North Atlantic Right Whale Consortium, said he and other scientists have documented an alarming decline in right whale calving rates alongside a rise in deaths from fishing gear entanglement.

“We have years, not decades to fix this problem. The longer we wait, the harder the problem gets to fix.” Mr. Baumgartner said. “We don’t need more science to be done on this species. We need to act.”

While the situation is grave, he said, solutions including weaker fishing rope and an emerging ropeless fishing technology that could reduce the number of entanglements that kill or injure the whales.

North Atlantic right whales are about the size of a city bus, and individuals can be identified by unique patterns of callosities on their heads. The whales eat copepods, tiny crustaceans, to the tune of one or two tons a day, Mr. Baumgartner said, the caloric equivalent of about 3,000 Big Macs.

Right whales got their name because they were the “right” whales to pursue during the whaling era. The whales are slow-moving, live near shore, and float after they are killed, making them easier to drag ashore.

The population was decimated beginning around the time of the Revolutionary War. “They’ve been down for along time, but not out,” Mr. Baumgartner said.

More recently, scientists have closely monitored the population from the southern Atlantic calving grounds they visit in the winter to feeding grounds off New England and Canada. Two recent trends paint a dire picture, Mr. Baumgartner said. Last winter, five right whale calves were born, the smallest number scientists have documented in 17 years. So far, he said, no calves have been seen this year. “This year I fear may be worse,” he said.

WHOI Led Research Team to Develop System to Predict Changes in Ocean Temps

October 30, 2017 — WOODS HOLE, Mass. — A research team led by the Woods Hole Oceanographic Institution has received a federal grant to develop a system to predict changes in ocean temperature.

The system will estimate seasonal and year-to-year temperature changes in the Northeast U.S. Shelf, which is seeing some of the highest ocean warming rates in the world and is home to a highly productive and commercially important marine ecosystem.

The Northeast Fisheries Science Center in Woods Hole and Stony Brook University are also part of the research team.

“Changes in ocean temperature hugely impacts the living organisms in coastal waters,” said Young-Oh Kwon, an associate scientist in WHOI’s Physical Oceanography Department and lead investigator of the new project.

Right whale deaths called ‘apocalyptic’

October 23, 2017 — NEW BEDFORD, MASS. — Whale scholars, lobstermen, conservationists and government officials converged Sunday in Nova Scotia to save right whales.

“Everybody is running out of adjectives,” Defenders of Wildlife attorney Jane Davenport said of the death of 12 North Atlantic right whales since June in the Gulf of St. Lawrence and another three off the U.S., totaling 3 percent of the total population. “It’s apocalyptic. It really is.”

At the annual North Atlantic Right Whale Consortium meeting in Halifax, right whale researchers released their latest population tally of 451 for 2016, typically counted with a year’s lag. But it’s easy to see where next year’s number is headed given the 15 known deaths and only five known births, said consortium chairman Mark Baumgartner, a Woods Hole Oceanographic Institution scientist.

“2017 will be another year of decline,” Baumgartner said.

In early October, the Defenders of Wildlife and three other conservation groups sent a 60-day notice of intent to sue the National Marine Fisheries Service for failure to protect North Atlantic right whales from fishing gear entanglement, believed by researchers to be one of two primary right whale killers, along with ship strikes.

NE Council Receives 2017 Scallop Survey Overview and Progress Report on 2018 Management Measures in Framework 29

October 2, 2017 — The following was released by the New England Fishery Management Council:

During its late-September meeting in Gloucester, MA, the New England Fishery Management Council received a comprehensive overview of the “very successful” 2017 scallop survey season. The Council then reviewed the range of measures under development for Framework Adjustment 29 to the Atlantic Sea Scallop Fishery Management Plan. These measures, once fully developed and approved, will apply to the 2018 scallop fishing year, which will begin on April 1 instead of March 1 as in previous years.

Five separate groups contributed to the 2017 scallop surveys:

  • The Virginia Institute of Marine Science (VIMS) conducted dredge surveys in the Mid-Atlantic, Nantucket Lightship Area, and Closed Area II.
  • UMass Dartmouth School for Marine Science and Technology (SMAST) conducted intensive surveys of Closed Area I, Closed Area II, and the Elephant Trunk Area, along with broadscale surveys of Georges Bank and the Mid-Atlantic and a drop camera survey of Stellwagen Bank in the Gulf of Maine.
  • The Woods Hole Oceanographic Institution (WHOI), in partnership with Lund’s Fisheries, conducted a Habitat Camera Mapping System (HabCam) version 5 (v5) survey of the Northern Edge on Georges Bank.
  • Coonamessett Farm Foundation (CFF) conducted a HabCam v3 survey of the Nantucket Lightship Area, as well as a HabCam v3 survey on Stellwagen Bank and Jeffreys Ledge in the Gulf of Maine, along with six dredge tows on Stellwagen. And,
  • The Northeast Fisheries Science Center (NEFSC) conducted a dredge survey on Georges Bank and a HabCam v4 survey of the Mid-Atlantic and Georges Bank.

Drifters May Help Improve Regional Harmful Algal Bloom Forecasts in Gulf of Maine

June 14, 2017 — The following was released by NOAA:

Every few weeks for the next few months, a pair of ocean drifters, one surface and one deeper, will be deployed from a ferry north of Grand Manan Island in the Bay of Fundy. Both will be tracked as part of a project to monitor the flow of water in and out of the bay and perhaps into the Gulf of Maine, providing insight into harmful algal blooms in the Gulf of Maine. 

Northeast Fisheries Science Center oceanographer Jim Manning is deploying and tracking the drifters for a two-year joint project with the Woods Hole Oceanographic Institution as part of its NOAA-funded Ecology and Oceanography of Harmful Algal Blooms research program. Researchers have developed models to forecast the annual severity of the blooms and provide weekly forecasts of bloom location and magnitude. These models are becoming operational and will be refined using data collected from a variety of instruments, including Manning’s drifters.The first pair of drifters was deployed May 25, the second pair June 7.

Researchers study whales and the food they eat

April 24, 2017 — North Atlantic right whales need a lot of food each day — the caloric equivalent of 3,000 Big Macs — and right now there’s plenty of it in Cape Cod Bay, in the form of a tiny crustacean.

“The food resource is the thickest we have seen in 32 years,” Charles “Stormy” Mayo, head of the right whale ecology program at the Center for Coastal Studies, said of the zooplankton that whales consume.

In years past, the center’s water sampling in the bay has shown total zooplankton densities usually less than 5,000 organisms per cubic meter. While the individual zooplankton are measured in millimeters, the whales that eat them are among the largest animals on earth, reaching lengths of more than 50 feet and weighing up to 79 tons.

But on April 14, for example, the densities reached well over 40,000 organisms per cubic meter across most of the bay, according to Christy Hudak, the center’s associate scientist. Some areas west of Great Island in Wellfleet reached 72,000 organisms per cubic meter.

On that same day, more than 40 percent of the total population of right whales left in the world, 217 out of 524, were spotted in the bay.

“It might be that the food resource is particularly strong this year, and if it continues that will bode well for right whales,” biologist Mark Baumgartner of the Woods Hole Oceanographic Institution said. “Alternatively, food in other habitats at other times of the year may be poor, leading to right whales concentrating in fewer places and fewer times, such as Cape Cod Bay in early spring.”

Scientists are looking at possible connections between the high concentration of right whales in the early spring in Cape Cod Bay and low calving rates.

UN official visits Woods Hole to recruit scientist advocates

April 11, 2017 — Standing in a high-ceilinged work bay on the Woods Hole Oceanographic Institution’s Quissett Campus, United Nations General Assembly President Peter Thomson was surrounded by sophisticated ocean sensors, robot gliders and moorings that towered overhead, bristling with technology.

“As a young boy in Fiji, I read my National Geographic, and saw the photos of Woods Hole and bathyscaphe sailing out of here, and this has always been a place where I thought, at least there’s some place where the good science is going on,” Thomson told scientists and media Friday at a briefing held during his tour of the institution’s facilities.

Thomson said he came to WHOI to ask that the organization send scientists to the upcoming UN Ocean Conference, which will be held June 5-9 in New York City.

“I’m an advocate, I’m not a scientist,” Thomson said. “It’s very important to me if I can seduce these guys at Woods Hole to come down and play an active role.”

WHOI Director Mark Abbott embraced Thomson’s request.

“It is a recommitment of a lot of things we do and we will be an active participant,” Abbott said.

WHOI is already involved in international research and projects, and had a program that sponsored scientists from around the world doing research at the institution, he said.

Thomson is a career civil servant and diplomat, has been his country’s permanent representative to the United Nations in New York since 2010, and served as the Fijian Ambassador to Cuba until he was selected as President of the General Assembly this year.

Troubling signs for right whale population

April 10, 2017 — The quickly fading population of vaquitas sets a worrisome example for those trying to save North Atlantic right whales.

“It has me slightly terrified,” said Woods Hole Oceanographic Institution biologist Mark Baumgartner, who heads up the North Atlantic Right Whale Consortium, at the annual U.S. Marine Mammal Commission meeting, held last week at the Sea Creat Beach Hotel in North Falmouth.

In 1997, scientists first counted 567 of the small porpoises in the Bay of California in Mexico, but in 20 years that has dropped precipitously — to 30 — as the vaquitas drown when caught underwater in gillnets.

The North Atlantic right whale population, at 524 animals, is currently on a downward trend, too, members of the consortium announced in November. This year’s low calving rate —only 3 right whale calves were documented — is one thing, Baumgartner said.

But a low calving rate coupled with increasing deaths due to fishing gear entanglement spells trouble.

“What could we expect in the next 5 to 10 years?” he said.

At the annual commission meeting, scientists delivered the sobering news that, starting in October, several vaquitas would be captured in the wild and placed in a conservation area for safekeeping and breeding. A recent and intense market in China for the swim bladder of totoaba, which is caught illegally in the bay using gillnets, “caught everybody by surprise,” said Peter Thomas, Marine Mammal Commission International and Policy Program Director. The vaquitas get caught in the gillnets and drown; their corpses are then brought up with the fish and are discarded by the fishermen.

Long-term study planned in ocean south of Martha’s Vineyard

March 13, 2017 — A group of scientists is taking a deep dive into the salty waters and the food web south of Martha’s Vineyard.

Heidi Sosik, a senior scientist at the Woods Hole Oceanographic Institution, will use submersible robotic microscopes she helped design and build, as well as an array of other sophisticated scientific gadgets to gain a fuller understanding of the ecosystem on part of the continental shelf stretching from just south of the Vineyard to an area where coastal waters meet the open ocean.

The study, which will involve a group of scientists and researchers led by Sosik, is being funded with $6 million from the National Science Foundation.

“The goal is that these ecosystems will be studied indefinitely,” Sosik said.

The team of experts will scrutinize the very foundation of the marine food chain: tiny plankton invisible to the eye but which can be seen with the aid of powerful underwater microscopes. The goal is to determine patterns in the ocean’s food web and how and why they change over time, so better management practices can be developed.

Waters off the Northeast coast are rich in fish, which depend on plankton to survive and in turn support the vigorous regional fishing industry that’s existed there for centuries.
