Right whales stay in Cape Cod Bay longer, and later

June 16, 2022 — It isn’t high gas prices that changed the travel plans of right whales.

A new study in Global Change Biology by nine authors discovered that over the last couple of decades North Atlantic right whales are most active in Cape Cod Bay 18 days later than before.

That’s a shift — with a longer stay in the month of May — that could potentially bring the whales further into conflict with the region’s annual boating  and lobster season and require an extended season of protections.

“The state has a flexible rule in place — where they can extend fishing closures and small boat speed restrictions — that now is in place up the coast to New Hampshire,” the study’s lead author, Dan Pendleton of the New England Aquarium, said. “Massachusetts Bay has seen more right whales than it used to.”

“One of the problems with migratory animals is they can get into big trouble moving into shipping lanes so if we can move and adapt the protections as (whales) adapt to climate change, that would be ideal,” Pendleton said. “So much seems out of our control but one thing we can do is push for regulations that are responsive to the needs of an endangered species.”

Beth Casoni, executive director of the Massachusetts Lobstermen’s Association, hadn’t yet seen the study, which was published June 7. Casoni said, therefore, she couldn’t comment until she has been able to read it.

Scientists see long-term hope for Maine’s lobster fishery despite warming waters

June 13, 2022 — Dire predictions about the effects of global warming on Maine’s lobster population may be exaggerated and underestimate the potential that conservation measures have to preserve the fishery into the future.

Rapid warming in the Gulf of Maine and the collapse of lobster fisheries in southern New England have fueled predictions that lobsters will likely move north out of Maine waters in the coming decades. But ongoing research at the University of Maine is revealing a more optimistic long-term view of the Maine lobster fishery.

The UMaine scientists are now projecting that temperatures in Gulf of Maine will likely remain within lobsters’ comfort zone because of the gulf’s unique oceanographic features, though changing ocean currents are harder to predict. The researchers cautioned that the dynamics of global warming are complex and make it difficult to project far into the future with certainty.

Ocean stratification – where water of different densities separates into distinct layers – is keeping the bottom temperatures colder on the Gulf of Maine’s western side, the scientists say, while strong tidal mixing in the eastern gulf and the Bay of Fundy helps moderate the water temperature there during the summer. Because Maine waters have historically been so cold, they say, even a couple of degrees of warming should keep Maine’s bottom waters below 68 degrees, the temperature at which lobsters begin to show signs of stress, according to the Atlantic States Fisheries Management Council.

New research shows climate change impacts on whale habitat use in the warming Gulf of Maine

June 10, 2022 — New research finds climate change is having an impact on how large whale species, including the critically endangered North Atlantic right whale, use habitats in the warming Gulf of Maine, showing that right whales’ use of Cape Cod Bay has shifted significantly over the last 20 years.

The study, led by the New England Aquarium and including researchers from the University of Massachusetts Amherst, the USGS Northeast Climate Adaptation Science Center, the Center for Coastal Studies, UCLA, the National Marine Fisheries Service, and the Canadian Whale Institute was published this month in the journal Global Change Biology. The authors set out to better understand the impacts of ocean climate change on phenology, or the timing of recurring biological events such as when plants flower each year. Using more than 20 years of data, the scientists measured shifts in whale habitat use in Cape Cod Bay, evaluating trends in peak use for North Atlantic right whales, humpback whales, and fin whales. The study found that peak use of Cape Cod Bay had shifted almost three weeks later for right whales and humpback whales. Changes in the timing of whale habitat use were related to when spring starts, which has been changing as a result of climate change. The study suggested that highly migratory marine mammals can and do adapt the timing of their habitat use in response to climate-driven changes in their environment, with results showing increased habitat use by right whales in Cape Cod Bay from February to May, with greatest increases in April and May.

“The time of year when we are most likely to see right and humpback whales in Cape Cod Bay has changed considerably, and right whales are using the habitat much more heavily than they did 20 years ago,” said lead author Dr. Dan Pendleton, Research Scientist in the New England Aquarium’s Anderson Cabot Center for Ocean Life.

NASA-funded Study: Gulf of Maine’s Phytoplankton Productivity Down 65%

June 8, 2022 — The Gulf of Maine is growing increasingly warm and salty, due to ocean currents pushing warm water into the gulf from the Northwest Atlantic, according to a new NASA-funded study. These temperature and salinity changes have led to a substantial decrease in the productivity of phytoplankton that serve as the basis of the marine food web. Specifically, phytoplankton are about 65% less productive in the Gulf of Maine than they were two decades ago, scientists at Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine, report in new results published today.

The Gulf of Maine helps fuel New England’s marine ecosystems and economy. Like plants on land, phytoplankton absorb carbon dioxide from the atmosphere and use photosynthesis to grow, and then become a food source for other organisms. Disruptions to their productivity can lead to adverse effects on the region’s fisheries and the communities that depend on them.

“Phytoplankton are at the base of the marine food web on which all of life in the ocean depends, so it’s incredibly [significant] that its productivity has decreased,” says William Balch, the Bigelow Laboratory scientist who led the study. “A drop [of] 65% will undoubtedly have an effect on the carbon flowing through the marine food web, through phytoplankton-eating zooplankton and up to fish and apex predators.”

NOAA says status report shows U.S. fisheries ‘on track’ with rebuilding

May 18, 2022 — The federal government’s 2021 annual report on the state of U.S. fisheries portrays progress in managing the nation’s marine resources – even with the massive wallop the seafood industry took with the covid-19 pandemic.

The National Oceanic and Atmospheric Administration and its National Marine Fisheries Service released the annual summary on May 12, updating the status of 460 fish species in U.S. waters.

“NOAA’s annual Status of Stocks report shows that the United States continues to be a global leader in sustainable fisheries management, as we work to understand how climate change is affecting fisheries and the communities that this sector supports,” said NOA Administrator Rick Spinrad. “The report demonstrates that we remain on track to maximize marine fishing opportunities while ensuring long-term ecological and economic sustainability in our changing world.”

Updated stock assessments and other metrics show improvement “in the face of climate change” and the economic value of fisheries “remain strong” at $4.8 billion in 2020 with 8.4 billion pounds landed, said Janet Coit, NOAA’s assistant administrator for fisheries, in a May 12 conference call with news reporters.

The climate is changing much faster than fishing regulations are evolving

May 2, 2022 — Officials who oversee fishing in the Gulf of Maine and the entire East Coast are taking a hard look at how fishery regulations will need to evolve in order to keep up with the accelerated and unpredictable changes wrought by climate change.

Fishery managers from organizations across the eastern seaboard are brainstorming scenarios they could face in the coming decades as water temperatures rise, fish stocks fluctuate and species push into new areas.

Several fishery experts said they’ll likely have to reimagine how management has worked in the past.

“I think people are recognizing that small little tweaks and band aids might not be what we need here,” said Deirdre Boelke, a fishery analyst at the New England Fishery Management Council and one of the leaders working on the scenario planning effort.

Even before the effects of climate change were more widely known, fisheries management had a reputation for being complex and cumbersome. There are various layers of governance, with councils and managers making decisions at the state, regional, coastwide and national levels.

“To say that it’s a glacial process is putting it kindly,” said Gib Brogan, a fisheries analyst at Oceana, an international conservation group.

Ocean animals face a mass extinction from climate change, study finds

April 29, 2022 — Not since an asteroid wiped out the dinosaurs — along with at least half of all other beings on Earth — has life in the ocean been so at risk.

Warming waters are cooking creatures in their own habitats. Many species are slowly suffocating as oxygen leaches out of the seas. Even populations that have managed to withstand the ravages of overfishing, pollution and habitat loss are struggling to survive amid accelerating climate change.

If humanity’s greenhouse gas emissions continue to increase, according to a study released Thursday, roughly a third of all marine animals could vanish within 300 years.

The findings, published in the journal Science, reveal a potential mass extinction looming beneath the waves. The oceans have absorbed a third of the carbon and 90 percent of the excess heat created by humans, but their vast expanse and forbidding depths mean scientists are just beginning to understand what creatures face there.

Yet the study by Princeton University earth scientists Justin Penn and Curtis Deutsch also underscores how much marine life could still be saved. If the world takes swift action to curb fossil fuel use and restore degraded ecosystems, the researchers say, it could cut potential extinctions by 70 percent.

“This is a landmark paper,” Malin Pinsky, a Rutgers University biologist who did not contribute to the paper, said in an interview. “If we’re not careful, we’re headed for a future that I think to all of us right now would look quite hellish. … It’s a very important wake-up call.”

More Endangered Right Whales Are Leaving New England for Canada

April 25, 2022 — Local researchers are studying why North Atlantic right whales are migrating out of our area into more northern waters in Canada.

Some believe rapidly warming waters in the Gulf of Maine could be playing a role, but they’re just not sure how.

The North Atlantic right whale is one of the most critically endangered animals on the planet.

Researchers from the New England Aquarium are studying these majestic creatures and they think some of the answers might lie in their poop.

Dr. Elizabeth Burgess is a research scientist with the aquarium that studies hormone changes in right whales. Unfortunately, the easiest way to collect hormones is through their feces.

“So nutritional stress is of really great concern for this species, as is the reproductive viability as well. So all of these things we can, we’re using hormones to better understand what’s happening,” said Burgess.

These whales are on the brink. Now comes climate change — and wind power.

April 22, 2022 — About 17 nautical miles south of Nantucket, a half-dozen New England Aquarium researchers scrambled across this vessel’s icy deck. Clutching binoculars, clipboards and cameras, they strained to catch a glimpse and scribble notes about a pair of creatures they fear are disappearing from this world.

After nine hours on the water, Amy Warren’s team had found two animals it knew by name. As the pair arched their heads above the water, the research scientist urged her colleagues with cameras to capture them.

“Get it, get it, get it, get it!”

With only about 300 left, the North Atlantic right whale ranks as one of the world’s most endangered marine mammals. Nearly annihilated centuries ago by whalers, the slow-swimming species is said to have earned its name because it was the “right” whale to hunt.

Old-fashioned harpoons have yielded to other threats. Humans are still killing right whales at startlingly high numbers — but by accident. Waters free from whalers now brim with ships that strike them, and ropes that entangle them.

The latest challenges come in a changing climate. Rising temperatures are driving them to new seas. And soon, dozens of offshore wind turbines — part of President Biden’s clean energy agenda — will encroach their habitat as the administration tries to balance tackling global warming with protecting wildlife.
