Scientists meeting in Portland say right whales on the way to extinction

November 18, 2019 — The future continues to grow ever darker for the highly endangered right whale, a species that has been in decline every year since 2010 and is at the heart of regulatory protection efforts threatening to upend Maine’s valuable lobster fishery.

The North Atlantic Right Whale Consortium estimates only 409 whales survived 2018, down from about 428 in 2017 and 457 in 2016. With seven births and 10 documented deaths in 2019 factored in, that tally is now probably about 406. Three of those are about to succumb to injuries.

“We are in yet another year of decline for the right whales,” said Mark Baumgartner, a researcher at the Woods Hole Oceanographic Institution and chairman of the consortium, which kicked off its annual right whale meeting Thursday in Portland. “This is extremely concerning.”

The meeting attracted hundreds of scientists, policymakers, animal rights advocates and several dozen curious fishermen. Topics ranged from new developments in how to safely tag a right whale to a review of right whale deaths in 2019 to the impact of whale-related fishery closures in Canada.

Why Are Birds and Seals Starving in a Bering Sea Full of Fish?

November 4, 2019 — The shipment arrived airfreight: 47 seabird carcasses collected by the Bering Strait villagers of Shishmaref.

Marine biologist Gay Sheffield drove to the airport on an August day to pick up the grisly cargo and bring it back to a laboratory just off the main street of this northwest Alaska town.

Inside a cardboard box, Sheffield found mostly shearwaters, slender birds with narrow wings — also kittiwakes, crested auklets, thick-billed murres, a cormorant and a horned puffin. Most were painfully skinny, bones protruding like knife-edged ridges.

“They starved to death,” Sheffield said. “Why?”

The birds should have been able to fatten on small fish, krill and other food that typically abound in the northern Bering Sea, a body of water so rich in marine life that gray whales, after they winter off Mexico, swim more than 5,000 miles north to feed here each summer.

But as climate change warms the die-offs of seabirds and marine mammals have been on the rise. The grim tally includes a nearly fivefold increase in ice-seal carcasses spotted on shore, strandings of emaciated gray whales, and near the St. Lawrence Island village of Savoonga, a discouraging spectacle: auklets abandoning seaside nests as their chicks succumb to hunger.

New paper shows evidence of tuna spawning in marine protected areas

August 30, 2019 — New research showed that there is evidence of tuna spawning inside the large marine protected area of the Phoenix Islands in the Pacific nation of Kiribati.

The research conducted by MIT and the Woods Hole Oceanographic Institution points to evidence that marine protected areas (MPAs) can play a critical role in protecting adult fish, including highly migratory species such as tuna, during spawning.

Boaty McBoatface makes major climate change discovery on maiden outing

June 18, 2019 — Boaty McBoatface’s maiden outing has made a major discovery about how climate change is causing rising sea levels. Scientists say that data collected from the yellow submarines’s first expedition will help them build more accurate predictions in order to combat the problem.

The mission has uncovered a key process linking increasing Antarctic winds to higher sea temperatures, which in turn is fuelling increasing levels.

Researchers found that the increasing winds are cooling water on the bottom of the ocean, forcing it to travel faster, creating turbulance as it mixed with warmer waters above.

Experts said the mechanism has not been factored into current models for predicting the impact of increasing global temperatures on our oceans, meaning forecasts should be altered.

Boaty McBoatface – the publicly named robotic submersible carried on the research vessel RRS Sir David Attenborough – took its first expedition in April 2017, studying the bottom of the Southern Ocean.

University of Rhode Island to Join NOAA Cooperative Institute for the North Atlantic

May 24, 2019 — The following was released by the University of Rhode Island:

The National Oceanic and Atmospheric Administration (NOAA) announced that the University of Rhode Island Graduate School of Oceanography (GSO) will join the Cooperative Institute for the North Atlantic Region (CINAR) led by the Woods Hole Oceanographic Institution (WHOI).

Cooperative Institutes are NOAA-supported, non-federal organizations that have established outstanding research and education programs in one or more areas that are relevant to the NOAA mission. Cooperative Institutes’ expertise and facilities add significantly to NOAA’s capabilities, and their structure and legal framework facilitate rapid and efficient mobilization of those resources to meet NOAA’s programmatic needs.

CINAR will carry out innovative, multidisciplinary research that will help inform decisions for sustainable and beneficial management of the U.S. Northeast continental shelf ecosystem.

“The University of Rhode Island is pleased to have been selected among the eight leading research institutions to participate in the Cooperative Institute for the North Atlantic Region, a critical ecosystem that extends from Maine to Virginia and encompasses the marine coastlines of 11 states, as well as Vermont and the Connecticut, Delaware, Hudson and Susquehanna river watersheds,” said URI President David M. Dooley. “URI brings great depth and breadth of expertise in ecosystem management to assist in advancing our understanding of climate change and the very real challenges we face for the future.”

“URI’s Graduate School of Oceanography is delighted to be part of CINAR,” said GSO Dean Bruce Corliss. “We look forward to continuing our support of NOAA’s efforts in fisheries and coastal resilience in the New England coastal ecosystem with our partners over the next five years.”

NOAA names Woods Hole Oceanographic Institution to host cooperative institute

May 20, 2019 — The National Oceanic and Atmospheric Administration (NOAA) selected Woods Hole Oceanographic Institution (WHOI) to host NOAA’s Cooperative Institute for the North Atlantic Region (CINAR).

Cooperative Institutes are NOAA-supported, non-federal organizations that have established outstanding research and education programs in one or more areas that are relevant to the NOAA mission. Cooperative Institutes’ expertise and facilities add significantly to NOAA’s capabilities, and their structure and legal framework facilitate rapid and efficient mobilization of those resources to meet NOAA’s programmatic needs.

North Atlantic Ocean productivity has dropped 10 percent during Industrial era

May 7, 2019 — Virtually all marine life depends on the productivity of phytoplankton — microscopic organisms that work tirelessly at the ocean’s surface to absorb the carbon dioxide that gets dissolved into the upper ocean from the atmosphere.

Through photosynthesis, these microbes break down carbon dioxide into oxygen, some of which ultimately gets released back to the atmosphere, and organic carbon, which they store until they themselves are consumed. This plankton-derived carbon fuels the rest of the marine food web, from the tiniest shrimp to giant sea turtles and humpback whales.

Now, scientists at MIT, Woods Hole Oceanographic Institution (WHOI), and elsewhere have found evidence that phytoplankton’s productivity is declining steadily in the North Atlantic, one of the world’s most productive marine basins.

In a paper appearing today in Nature, the researchers report that phytoplankton’s productivity in this important region has gone down around 10 percent since the mid-19th century and the start of the Industrial era. This decline coincides with steadily rising surface temperatures over the same period of time.

Matthew Osman, the paper’s lead author and a graduate student in MIT’s Department of Earth, Atmospheric, and Planetary Sciences and the MIT/WHOI Joint Program in Oceanography, says there are indications that phytoplankton’s productivity may decline further as temperatures continue to rise as a result of human-induced climate change.

“It’s a significant enough decine that we should be concerned,” Osman says. “The amount of productivity in the oceans roughly scales with how much phytoplankton you have. So this translates to 10 percent of the marine food base in this region that’s been lost over the industrial era. If we have a growing population but a decreasing food base, at some point we’re likely going to feel the effects of that decline.”

Osman and his colleagues looked for trends in phytoplankton’s productivity using the molecular compound methanesulfonic acid, or MSA. When phytoplankton expand into large blooms, certain microbes emit dimethylsulfide, or DMS, an aerosol that is lofted into the atmosphere and eventually breaks down as either sulfate aerosol, or MSA, which is then deposited on sea or land surfaces by winds.

Equinor to support New York Bight whales monitoring

April 10, 2019 — Offshore wind power developer Equinor Wind US is entering a joint project with conservationists and scientists to deploy two new acoustic buoys to expand detection and monitoring of whales in the New York Bight.

To be operated with the Wildlife Conservation Society’s New York Aquarium and the Woods Hole Oceanographic Institution (WHOI) in Massachusetts, the buoys will provide near real-time monitoring of species including sei, fin and humpback whales, and the extremely endangered North Atlantic right whale.

The buoys will become a broader network with a previously deployed acoustic buoy, funded by the G. Unger Vetlesen Foundation and the Flora Family Foundation, now on station about 22 miles off New York.

WHOI Releases Report on Right Whale Threats, Solutions

April 1, 2019 — A new report has been released by the Woods Hole Oceanographic Institution which details the major threats facing critically endangered North Atlantic right whales.

The population for the species is estimated to be just over 400 and has suffered in recent years from high mortality rates with very few births.

The report indicates the whales are most threatened by fishing gear entanglements, vessel strikes and noise pollution.

WHOI Marine Biologist Michael Moore, who was a co-author of the report, says there has been a dramatic shift in the number of deaths caused by entanglements over the last decade.

Before 2010, 45 percent of right whale deaths were due to vessel strikes with 35 percent attributed to entanglements. Since 2010, entanglements have resulted in about 85 percent of right whale deaths.

“The entanglement rate has gone up and become more severe,” Moore said. “It used to be the animals would get entangled and scarred up and then be able to wiggle out of it or get disentangled, but now the entanglement mortality rate has also increased.”

Whale researchers are also concerned with the non-lethal effects of getting caught in fishing gear.

“Eighty-plus percent of the species show entanglement scars and 25 percent of them get new scars every year,” Moore said. “So the majority don’t die but they do have sub-lethal impact and really it comes down to stress of being entangled and pulling the rope through the water and traps too if they are involved.”

WHOI Scientists Studying Phytoplankton to Improve Satellite Operations in Space

November 26, 2018 — WOODS HOLE, MASS. – Researchers from Woods Hole are working to improve the quality of data collected by satellites over 500 miles above the ocean.

The goal is to determine how microscopic algae, also known as phytoplankton, absorb and scatter light, and how the colors of the phytoplankton can be better identified and measured.

For the next three years, researchers from NOAA Fisheries and colleagues at the University of Rhode Island, NOAA’s National Environmental Satellite, Data and Information Service, and Woods Hole Oceanographic Institution will look into the ocean to help improve the quality of data collected by satellites more than 500 miles above.
