Solving a mystery: How researchers found missing North Atlantic right whales

December 27, 2021 — Until recently, researchers tracking the well-being of the world’s most endangered great whale could count on North Atlantic right whales showing up in several key areas at certain times of the year seeking food, love, or a safe place to give birth.

In winter and early spring, a large portion of right whales could be found in Cape Cod Bay feeding on copepods, their favorite food. They then moved to the Bay of Fundy for summer feeding, where New England Aquarium researchers had been studying them since the 1980s.

But in 2010, and in the years to follow, they went missing. Although they still showed up in Cape Cod Bay, for the past decade the Bay of Fundy has been largely a right whale ghost town. The same was true for the Great South Channel east of Cape Cod and the northern edge of Georges Bank.

It took a combination of detective work and luck to eventually find them — and where they ended up dramatically altered the landscape for whale survival and fisheries management.

Search continues for 5 fishermen in Bay of Fundy after 1 found dead

December 16, 2020 — Searchers found the body of a crew member from a scallop vessel that went missing in the Bay of Fundy off the coast of southwestern Nova Scotia Tuesday, as teams combed the air and shores for five other missing men.

The Maritime Joint Rescue Co-ordination Centre (JRCC) announced the news in a tweet late Tuesday.

“Our thoughts and sincere condolences go out to the family,” the JRCC tweet said. It’s unclear when the body was found or where. Next of kin have been notified.

The emergency beacon was activated for the missing vessel, Chief William Saulis, Tuesday morning. The JRCC said the emergency signal came in at 5:51 a.m. AT near Delaps Cove, N.S.

A Cormorant helicopter and a Hercules aircraft from CFB Greenwood and three coast guard ships were dispatched to help with the search, which is being hampered by bad weather.

A CP-140 Aurora Maritime Patrol Aircraft from Greenwood also joined the search Tuesday evening.

Scientists Have Not Detected A Single Right Whale In The Bay Of Fundy This Year

October 15, 2020 — For the first time in four decades, marine scientists were unable to find any North Atlantic right whales in the Bay of Fundy this year.

“Always we would have a handful, even in recent years. So to have zero is certainly disturbing or frustrating,” says Amy Knowlton, a New England Aquarium whale researcher who has been tracking the endangered species from a base in Lubec every year since the early 1980s.

She says that for decades, anywhere from a 50-150 right whales showed up in the summer and fall to forage. The numbers started to drop off around 2010, as water temperatures in the Bay and Gulf of Maine began to rise at a rapid clip.

“It’s just a reflection of how the ocean is changing with climate change, and their food resource, plankton, they’re not blooming at the same time and in the same areas that they used to, so it’s a reflection that for them and for our oceans things are changing pretty dramatically,” Knowlton says.

Warmed waters linked to diminished food for right whales

June 4, 2019 — Overheated waters pouring into the Gulf of Maine from deep ocean reserves along the Atlantic coast appear to be diminishing the food supply on which North Atlantic right whales rely.

A new report from Oceanography says warming temperatures in the gulf are impacting densities of zooplankton, which the whales rely on for food.

The rapid pace of change near the Bay of Fundy, in particular, now indicates that traditional methods of protecting the whales, including protecting their decadeslong feeding areas, may need to be refined.

“Climate change is outdating many of our conservation and management efforts,” said the report’s lead author, Nicholas Record, a senior research scientist at the Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine.

Border Patrol Stops Canadian Fishermen in Disputed Waters Off Maine

July 9, 2018 — As tensions rise between the United States and Canada, there’s a new clash in the cool waters off the northeast tip of Maine, which are rich with lobster, scallops and cod.

For more than a decade, American and Canadian fishermen largely have had a friendly but competitive relationship in an oval-shaped region of the Bay of Fundy known as the gray zone. But this summer that camaraderie has been threatened, Canadian fishermen claim, as officers with the United States Border Patrol have started to wade into the area, pull up aside their vessels and ask about their citizenship.

“We don’t want this to be a great international incident, but it’s kind of curious,” said Laurence Cook, the chairman of the lobster committee at the Grand Manan Fishermen’s Association in New Brunswick. “They say it’s routine patrolling, but it is the first routine patrolling in 25 years.”

At least 10 Canadian fishing boats have been stopped by American immigration authorities within the past two weeks, Mr. Cook said, the latest escalation in a more than 300-year disagreement in the disputed waters off Machias Seal Island. Both countries claim the island, which is about 10 miles off Maine and home to two full-time residents (both Canadian), puffins, rocks and not much else, and say they have the right to patrol its boundaries.

Path to extinction for North Atlantic right whales

March 26, 2018, PROVINCETOWN, Mass. — Inside the cabin of the research vessel Shearwater, Charles “Stormy” Mayo, senior scientist and director of the Right Whale Ecology Program at the Center for Coastal Studies, pulled up on his computer an image of the family tree of North Atlantic right whale #1140.

This whale — dubbed “Wart” by researchers — has a file of photographs, identifying marks, and a life history, as does nearly every one of the remaining 451 right whales on earth.

“Her productivity has been extraordinary,” Mayo said. But Wart hasn’t been seen since 2014, and some worry her fabled life may have come to an end.

Last summer was particularly tragic with 16, possibly 17, right whales — 4 percent of the remaining population — killed after being hit by ships, entangled in fishing gear, and other unknown causes.

Extinction, experts say, is suddenly a reality.

“It was one of the big stories of the day, that right whales were coming back,” Mayo said. “But up to 2010, you had this appallingly slow climb, then decline. Now we have a species that is clearly headed for extinction.”

Wart, first seen in 1981, at the dawn of right whale research, has been subsequently spotted and identified 66 times from the Bay of Fundy to Florida. Believed to be in her 50s now, she is one of the more successful breeders — mother to seven calves, grandmother to 13 and great-grandmother to six.

But that productivity may not be enough in the face of a host of environmental issues related to an increasingly urbanized ocean — vessel noise, pollution and oil and gas exploration — and the unknown complications from a rapidly warming sea that could affect, for example, the seasonal timing of critical right whale food.

Then, there is the intractable problem of human induced mortality and serious injury.

Sixteen deaths last summer caused many to hit the panic button. Researcher Brian Sharp called it shocking.

“It begs the need for fishery managers, the industry and scientists to push harder to find solutions,” said Sharp, manager of Marine Mammal Rescue and Research at the International Fund for Animal Welfare in Yarmouth.

Twelve of last year’s deaths occurred in the Gulf of St. Lawrence, where right whales had been seen sporadically over the last four decades, fewer than a dozen a year, and not well-documented. Five live entanglements also were documented in that area last year. Unlike the U.S., Canada has had no ship or fishing restrictions in place as the numbers of whales documented in the Gulf, possibly following prey driven north by climate change, has grown.

But four deaths also happened in the U.S. last year, despite decades of research and planning on how to create whale-safe fishing gear, massive fishing closures and rerouted and slowed ships to avoid fatal interactions with whales. The U.S. deaths alone were four times the number scientists set as the maximum allowed per year if the species is going to recover.

“There’s a huge misconception that the industry is not sensitive to this matter or not aware of it. We certainly are, and it concerns the industry a lot,” said Grant Moore, of Westport, a longtime offshore lobsterman and president of the Atlantic Offshore Lobstermen’s Association.

The exact number of North Atlantic right whales that existed prior to human killing is unknown, but the population was likely reduced to fewer than 100 by the time the international 1935 ban on whaling was enacted.

Right whale survival may be dependent on snow crab fishery’s flexibility

March 22, 2018 — The future of the North Atlantic right whale is looking more and more bleak, and with their fate inextricably tied to the lobster and crab fishing grounds off the coast of Northern New England and Eastern Canada, pressure is mounting on the fisheries and their regulators to take more drastic action.

No right whale calves have been spotted so far this year – the latest in a string of bad news for the species, which lost 17 members in 2017. That total represented about four percent of its remaining population, and was around six times the normal mortality of the whales.  An eighteenth dead whale was found entangled in fishing gear off the coast of Virginia in January. Gear entanglement, followed by blunt force trauma caused by collisions with ships, have been identified as the main causes of these deaths.

Philip Hamilton, a research scientist at the Anderson Cabot Center for Ocean Life at the New England Aquarium, who studies the mammals, said there’s slim hope remaining that researchers have missed spotting any new calves.

“The calving season isn’t considered completely over – the folks who are doing the surveys on the calving grounds off of Florida and Georgia will be going for another month, but we’ve never gone this long and not found a calf,” Hamilton said. “And there are only a few whales that have not been seen, so we’re not particularly optimistic that a calf will be seen down there.”

With only an estimated 100 breeding females left in the entire North Atlantic right whale population, scientists are closely monitoring the changing reproductive cycle of the whales.

“We have had drops in reproduction in the past. We had a dip in the early 1990s and then a pretty dramatic downturn in the late 1990s that culminated with just a single right whale calf born in 2000. So we have seen this before, but we’ve never seen it in conjunction with such extremely high mortality,” Hamilton said.

In addition to the premature deaths and low birth rate, the right whale species faces the new and additional challenge of a lengthier gestation period. According to Hamilton,  their inter-birth interval has been increasing over the last five or six years, going from the standard of three to four years to 6.6 years in 2016, and jumping to an average of 10.2 years in 2017.

“There is a lot going on for them. We do know that females will forego reproduction if they aren’t in adequate body condition, meaning they have to have substantial fat reserves to support a calf. They end up losing up to a third of their body weight nursing a calf, so they have be able to handle that,” Hamilton said. “And there are a couple of factors which may be impacting female body condition. One would be food availability.”

The whales have been shifting where they feed in recent years and largely not going to some of their standard, historically productive feeding grounds like the Bay of Fundy and Roseway Basin and Great South channel east of Cape Cod. Instead, last year many ended up in Canada’s Gulf of St. Lawrence, where they are in much greater danger of entanglement with fishing gear, Hamilton said.

Northeastern U.S. fisheries feeling effect of warming

March 5, 2018 — NEW BRUNSWICK, Canada — It is in the upper reaches of Canada’s Bay of Fundy where nature flexes its tidal muscles while sending a surge of 160 billion tons of seawater in and out of the funnel-shaped bay. That mass moves in with the force equal to that of 8,000 locomotive engines, scouring nutrients from the ocean bottom, the tidal flats and marshes, while stirring up a smorgasbord of food for the whales, waterfowl, fish and seafloor dwellers that make this rich fishery their home.

The tides, the highest in the world, are equal in height to a five-story building when they play out in their most extreme manner. With two high tides and two low tides each day, that mega-slosh of water, a volume greater than the combined flow of all of the freshwater rivers on the planet, refreshes and invigorates the Bay of Fundy, which joins the Grand Canyon and Yellowstone National Park among the seven wonders of North America.

And also, it is in this bay where the warming of the planet’s oceans could be showing its hand.

Donald Killorn is the executive director at Eastern Charlotte Waterways Inc., an environmental resource and research center located in Blacks Harbour, not far from where the Bay of Fundy merges into the adjoining and much wider Gulf of Maine. Mr. Killorn says these waters, the fishery and the impact they are experiencing because of a rising water temperature brought on by climate change know no international boundary.

“The temperature change we are experiencing here in the Bay of Fundy and in the Gulf of Maine is as severe as anywhere on the planet, and it is having a significant impact on the biodiversity of these waters,” Mr. Killorn said.

Fishing industry cautiously optimistic about potential haddock boom

January 23, 2017 — Exactly how many of the haddock that hatched in 2013 are still swimming off the coast of southern Nova Scotia is not certain, but researchers agree the numbers are potentially massive.

Biologist Monica Finley recently completed a population assessment for the southern Scotian Shelf and Bay of Fundy.

She estimates 264 million haddock were hatched there in 2013 and survived their first year, making it an “extraordinary” year-class.

“This 2013 year-class is five times higher than the next highest on record since 1985,” said Finley, who works at a Department of Fisheries and Oceans research facility in St. Andrews, N.B.

Her report predicts 100,000 metric tonnes of haddock will reach adulthood in 2017 and 2018.

Bring on the boom

On Georges Bank, the population is predicted to be even bigger, with Canadian and American scientists estimating the 2013 hatch at 1.3 billion fish.

This month, fish plants in southern Nova Scotia are starting to process their first catches of 2013 haddock, forerunners of what industry members hope is a boom for years to come.

“We’re seeing signs of it now, but we would expect to see the fish at the larger, more commercially harvestable sizes in a couple of years,” said Alain d’Entremont, chief operating officer at O’Neil Fisheries in Digby.

“We are taking a cautious path to that harvest.”

MAINE: Big changes are occurring in one of the fastest-warming spots on Earth

October 25, 2015 — Sandwiched on a narrow sandbar between Yarmouth’s harbor and the open Gulf of Maine, the fishermen of Yarmouth Bar have long struggled to keep the sea at bay.

Nineteenth-century storms threatened to sweep the whole place away, leaving Yarmouth proper’s harbor more open to the elements, prompting the province to build a granite cribwork across the quarter-mile bar, behind which the hamlet’s fishing fleet docks. Global warming has brought rising seas, a two-story-high rock wall to fight them and the hamlet’s designation as one of the communities in the province most threatened by climate change.

Now, snaking around the snout of Nova Scotia and into the Gulf of Maine is a new, unseen threat to Yarmouth Bar and hundreds of coastal communities in Maine, eastern New England and the Maritimes: currents fueling the rapid warming of the sea.

The Gulf of Maine – which extends from Cape Cod in Massachusetts to Cape Sable at the southern tip of Nova Scotia, and includes the Bay of Fundy, the offshore fishing banks, and the entire coast of Maine – has been warming rapidly as the deep-water currents that feed it have shifted. Since 2004 the gulf has warmed faster than anyplace else on the planet, except for an area northeast of Japan, and during the “Northwest Atlantic Ocean heat wave” of 2012 average water temperatures hit the highest level in the 150 years that humans have been recording them.
