‘Truly alarming’: No babies for endangered right whales

March 27, 2018 — SAVANNAH, Ga. — The winter calving season for critically endangered right whales has nearly ended with zero newborns spotted in the past four months — a reproductive drought that scientists who study the fragile species haven’t seen in three decades.

Survey flights to look for mother-and-calf pairs off the Atlantic coasts of Georgia and Florida are scheduled to wrap up when the month ends Saturday. Right whales typically give birth off the southeastern U.S. seacoast between December and late March. Researchers have recorded between one and 39 births each year since the flights began in 1989.

Now experts are looking at the possibility of a calving season without any confirmed births.

“It’s a pivotal moment for right whales,” said Barb Zoodsma, who oversees the right whale recovery program in the U.S. Southeast for the National Marine Fisheries Service. “If we don’t get serious and figure this out, it very well could be the beginning of the end.”

Zoodsma said she doesn’t expect any last-minute calf sightings this week.

The timing could hardly be worse. Scientists estimate only about 450 North Atlantic right whales remain, and the species suffered terribly in 2017. A total of 17 right whales washed up dead in the U.S. and Canada last year, far outpacing five births.

With no rebound in births this past winter, the overall population could shrink further in 2018. One right whale was found dead off the coast of Virginia in January.

“It is truly alarming,” said Philip Hamilton, a scientist at the New England Aquarium in Boston who has studied right whales for three decades. “Following a year of such high mortality, it’s clear the population can’t sustain that trajectory.”

Right whales have averaged about 17 births per year during the past three decades. Since 2012, all but two seasons have yielded below-average calf counts.

Scientists will be looking for newborn stragglers as the whales return to their feeding grounds off the northeastern U.S. this spring. That happened last year, when two previously unseen babies were spotted in Cape Cod Bay.

Right whale researcher Charles “Stormy” Mayo of the Center for Coastal Studies in Provincetown, Massachusetts, said he was hopeful some calves were born this season off the Carolinas or Virginia, where scientists weren’t really looking.

It’s also possible right whales could rally with a baby boom next year. Females typically take three years or longer between pregnancies, so births can fluctuate from year to year. The previous rock-bottom year for births — just one calf spotted in 2000 — was followed by 31 newborns in 2001, the second-best calving season on record.

NOAA closes areas to protect whales

March 20, 2018 — As NOAA Fisheries continues to address the rising peril to whales in coastal waters stretching from New England to Florida, it is reminding local fishermen of current or impending gear closures off Massachusetts.

The closures, primarily around Cape Cod and in Cape Cod Bay, are part of NOAA Fisheries’ Atlantic large whale take reduction plan developed to provide increased protection to several species of whales — particularly the endangered North Atlantic right whales whose population continues to plummet.

Some of the gear closures impact trap and pot fishermen, while other impact gillnetters.

The closures have been greatly enlarged as part of a 2015 amendment to the large whale take reduction plan, according to Mike Asaro, the Gloucester-based marine mammal and sea turtle branch chief for NOAA Fisheries.

“The Cape Cod Bay closure has been greatly expanded northward and out beyond the outer Cape toward Nantucket,” Asaro said.

The closest closure to Cape Ann is the Massachusetts Restricted Area that encircles Cape Cod, with its northwest corner approaching the southern end of Cape Ann. The area is closed to all trap and pot fishing until April 30.

The Great South Channel restricted area, which sits to the east and southeast of Cape Cod, will be closed to all trap and pot fishing from April 30 until June 30. The Great South Channel also will be closed to all gillnetting during the same time.

Gillnetters also will be prohibited from fishing in the Cape Cod Bay restricted area until May 15.

Asaro said the closures are just one element in NOAA Fisheries’ strategy for mitigating dangers to the whales from gear and other man-made obstacles in the ocean’s waters.

Massachusetts: No, sharks aren’t just freezing to death in Cape Cod Bay. But they are getting trapped

January 4, 2018 — Frigid temperatures may have transformed the waters off Cape Cod to ice, but it turns out the recent cold snap is not literally just freezing sharks to death.

It may, however, be contributing to the ocean predators getting trapped in Cape Cod Bay.

Greg Skomal, the senior fisheries scientist for the state Department of Fish and Game who leads the Massachusetts Shark Research program, said the thresher sharks — like the four that have been found dead in Wellfleet and Orleans in recent days — are dying as they attempt to swim to warmer southern waters but are getting stranded in shallow waters in Cape Cod Bay.

“The rapid cooling associated with this cold snap and water temps is forcing the sharks to move south at a faster pace, and the landmass of Cape Cod is contributing to them getting stranded in shallow water,” said Skomal, adding that the exact cause of the sharks’ deaths remains hypothetical at this time.

Cape Cod, with its shape of an outstretched human arm that hooks at Provincetown, can act as a natural trap for animals trying to move south quickly, and most shark species need to be continually moving in order to breathe effectively, he said.

Massachusetts: Cape and Islands Lawmakers Join Fight to Protect Offshore Herring

November 27, 2017 — CHATHAM, Mass. — The Cape Cod Commercial Fishermen’s Alliance is receiving support from the Cape and Islands legislative delegation in protecting offshore herring for local fishermen.

Earlier this month, the lawmakers called on the New England Fishery Management Council to create a buffer zone off the coast of the Cape and Islands from large-scale mid-water herring trawlers.

Current regulations allow the trawlers to fish three miles offshore from Provincetown past the Islands.

“The delegation has taken up a position that we staked out at the Fishermen’s Alliance years ago that we need a buffer zone,” said John Pappalardo, the alliance CEO.

“In other words, a zone off the Cape and Islands where these vessels cannot come in and intensively harvest sea herring.”

The alliance would like a 50 mile buffer zone.

Another right whale found dead

August 18, 2017 — There doesn’t seem to be an end to the bad news on right whales this summer. With a dozen found dead this year, most of them in a flurry of deaths since June, the Coast Guard reported right whale death number 13 Monday, 145 miles east of Cape Cod.

On Thursday, the whale was identified by matching the pattern of hardened patches of gray skin with photos found in a database at the New England Aquarium. The right whale Couplet was a frequent visitor to the Cape, arriving here first as a yearling in 1992, and seen in Cape Cod Bay mostly in April to feed on abundant plankton blooms for 15 of the 26 years of her life. The last time she was sighted here was in 2015, and she brought her last of her five calves to Cape Cod in 2014.

“We study this unique animal and it is hard not to get attached to it,” said Amy James, aerial survey coordinator for the Center for Coastal Studies in Provincetown. “You get used to seeing the same ones come back year after year.”

The loss of females is especially tragic, James said.

The Northwest Atlantic right whales are among the most endangered whale populations on earth with around 500 individuals and less than 100 breeding females.

“All of her future calves, the ones she could have gone on to create, that opportunity has been lost,” James said.

Tenth right whale found dead: ‘This population can’t sustain another hit’

August 3, 2017 — The first North Atlantic right whale to turn up dead in the Gulf of St. Lawrence was a 10-year-old male, back on June 7. Researchers had spotted it just six weeks earlier in Cape Cod Bay, looking healthy.

Another was a vital 11-year-old female that might have added at least five to 10 calves to the dwindling population.

Among the others: Two whales at least 17 and 37 years old, according to the New England Aquarium, which catalogues them through their distinctive white markings.

The 10th and most recent carcass of the critically endangered species found in the gulf was reported Tuesday, a horrendous die-off not seen since the docile, curious creatures were hunted for their oily blubber in the 1800s.

The federal Department of Fisheries said the “unprecedented number of right whale deaths is very concerning.”

It’s estimated there are only about 500 North Atlantic right whales still living, and Jerry Conway of the Canadian Whale Institute in Campobello, N.B., said the losses are disastrous for an already vulnerable species.

“We feel there is tremendous urgency,” he said Wednesday in an interview. “This has had catastrophic ramifications on the right whale population, this number of whales being killed when we only know of three calves being born this year.

“It certainly indicates a rapid decline in the population.”

Climate change puts Cape fisheries in hot water

June 19, 2017 — As the president claims that climate change is a “Chinese hoax” and members of Congress deny that it even exists, those of us who live at the ocean’s edge can testify firsthand to its effects. They include bigger storms, accelerated sea-level rise and warmer waters. On the Cape, those are game changers to a way of life. They affect the community’s character, soul, and livelihood, especially in the commercial fishery.

The biggest long-term threat to fishing in the northwest Atlantic is not excessive regulations, national marine monuments, or over-fishing – it’s hot water. Cold water species like the iconic cod, and even lobsters and northern shrimp, have to put up with living conditions so uncomfortable that they may be leaving home and heading north.

A recent issue of the journal “Science” shows that over the last 10 years, temperatures in the Gulf of Maine have increased three times faster than almost all of the Earth’s oceans. The Gulf’s southern boundary edges along Cape Cod Bay. Beginning there, Gulf surface temperatures increased four degrees between 2005 and 2013 and scientists tell us they could go even higher. That spells disaster for the Gulf’s ecosystem.

The world’s oceans absorb most of the heat humans produce, but when we deposit too much heat into the atmosphere and adjacent waters below, sea life pays the price. With nature out of balance, fisheries shift, oceans acidify, and life-sustaining oxygen levels decrease.

Especially alarming is what we are seeing at the lower levels of the food chain. As water temperatures spike, copepods are disappearing. These tiny plankton-like crustaceans anchor the Gulf’s food chain and when they leave, the chain starts to unravel from the bottom up and fish productivity suffers.

Excessive carbon dioxide emissions, one of the major causes of rapid climate change, are sapping the strength of the giant ocean conveyor belt known as the Atlantic Meridional Overturning Circulation — otherwise known as the AMOC. It’s a vital component of the Earth’s climate system, with a northward flow of warm tropical salty water in the upper layers of the Gulf Stream, and a southward flow of colder water in the deeper layers.

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.

MASSACHUSETTS: Cape Cod boaters asked to use caution due to presence of extremely endangered right whales

April 17, 2017 — Boaters have been urged by officials with the Division of Marine Fisheries (DMF) to use extreme caution when enjoying the waters of Cape Cod.

According to a statement released by the Massachusetts Department of Fish and Game on Friday, an unusually large amount of endangered North Atlantic right whales have been observed in the bay area.

The right whale, which is known to congregate and feed near the bay on an annual basis, is a species of whale so endangered that their entire population is only about 500 animals, the statement says.

An aerial survey conducted on April 12 by the Provincetown Center for Coastal Studies showed that roughly 163 of those whales were present in the Cape Cod Bay, meaning that some 30 percent of the known population of the species was sighted in the same bay on a single day.

“Aggregations of this magnitude have never been observed in Cape Cod Bay before,” said Gronendyke.

Boat owners have been urged to “proceed with extreme caution” and to reduce speed to less than 10 knots.
