Boats may be hitting whales in Gulf of Maine more often, study suggests

April 24, 2017 — A group of marine scientists says collisions of whales and boats off the New England coast may be more common than previously thought.

The scientists focused on the humpback whale population in the southern Gulf of Maine, a body of water off Massachusetts, New Hampshire and Maine. They found that almost 15 percent of the whales, which come to New England to feed every spring, had injuries or scarring consistent with at least one vessel strike.

The researchers, who published their findings in the March issue of the journal Marine Mammal Science, said the work shows that the occurrence of such strikes is most likely underestimated. They also said their own figure is likely low because it does not account for whales that are killed in ship strikes.

“Vessel strikes are a significant risk to both whales and to boaters,” said Alex Hill, the lead author of the study, who is a scientist with the conservation group Whale and Dolphin Conservation in Plymouth, Massachusetts. “Long-term studies can help us figure out if our outreach programs to boaters are effective, what kind of management actions are needed and help to assess the health of the population.”

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: Endangered whales visit Cape Cod in record number

April 13, 2017 — More than 100 North Atlantic right whales, including two mother-calf pairs, were spotted in Cape Cod Bay on Sunday, breaking a record for previous sightings, according to the Center of Coastal Studies.

An aerial survey team researching the rare marine mammal took thousands of photos of the 112 animals, which were scattered across two-thirds of the bay from the Cape Cod Canal to Provincetown, where there was a large concentration of the animals, according to Charles “Stormy” Mayo, right whale habitat expert at the center. There are 524 North Atlantic right whales in the world, according to the Center.

The number of right whales spotted may still increase, as researchers analyze the photographs taken during the flight, according to the center.

This year, only three right whale births were recorded, and two of those calves were spotted Sunday with their mothers, Mayo said. The number of calves has dropped precipitously during the past 10 years, from a high of 39 in 2009, according to data from the North Atlantic Right Whale Consortium.

“It’s a pretty special situation that this many whales and arithmetically two-thirds of the calf population was here in Cape Cod Bay,” Mayo said. “The people who fly in our airplanes, who are trained researchers, said all 112 animals had their mouths open.”

Scientists eye new tools for whale safety

April 10, 2017 — There are still limitations to the technology, but scientists hope the expanded use of unmanned listening devices and whale call recordings will help better protect whales by using the sounds they make.

“There are a lot of potential applications,” said Brian Sharp, International Fund for Animal Welfare’s manager of marine mammal rescue and research. “We’re just scratching the surface.”

At the Northeast Fisheries Science Center in Woods Hole, researchers have analyzed underwater recordings of North Atlantic right whale calls from 2006 through 2014 to try and address a question that has emerged in recent years: Why are the endangered animals not showing up as predictably in their seasonal haunts.

“One of the things that’s really been discussed is how they’re shifting their distribution patterns,” Genevieve Davis, a research analyst at the science center, said at the annual Marine Mammal Commission meeting held at the Sea Crest Beach Hotel.

For the 2006-2014 time period, the scientists ended up with 2,500 days that showed — by recorded sound — the presence of right whales from Iceland to Florida. In looking at the data, they learned that the whales are spending their winters all along the Atlantic coastline rather than in specific areas at specific times of the year. Also, from New England through the mid-Atlantic area, the analysis showed that there are right whales present “pretty much year-round,” Davis said.

Researchers: Where are all the right whales?

February 24, 2017 — MELBOURNE, Fla. — Maybe the right whales are all just in the wrong place at the wrong time this year.

Where spotters typically see 20 newborn North Atlantic right whales, this winter only three have been born, the lowest number of newborns since only one was born in 2000.

Three dozen or more adult and baby right whales usually pass through Florida and Georgia waters during the winter calving season, which runs mid-November to mid-April. This year, only seven whales have been documented.

“Not only is it the fewest number of calves, but it’s also the fewest number of individuals seen,” said Phil Hamilton, a research scientist at New England Aquarium, which monitors right whales.

Scientists suspect a warmer North Atlantic, driven in part by climate change, might be disrupting the density of animal plankton that the whales need to feed, increasing the time it takes for females to bulk up for pregnancy and forcing the whales to scatter in search of food.

“A lot of people are doing a lot of head scratching,” Julie Albert, who monitors right whales for the nonprofit Marine Resources Council, said of this winter’s whale migration.

Fishermen Object to New York Wind Farm Lease Sale

December 9th, 2016 — The Fisheries Survival Fund, which represents the majority of the limited access Atlantic scallop fleet, is the lead plaintiff in a lawsuit seeking to delay an anticipated lease sale for the development of offshore wind farms off New York.

A 26-mile long block approximately 11 miles off the coast of Long Island is scheduled for sale on December 15, 2016.

The Fund argues that the Bureau of Ocean Energy Management (BOEM) did not adequately consider the impact the proposed New York Wind Energy Area would have on the region’s fishermen. The site chosen is in the waters of the New York Bight on vital, documented scallop and squid fishing grounds, which serves as essential fish habitat and grounds for other commercially important species, including black sea bass and summer flounder. It is also an important foraging area for threatened loggerhead sea turtles and critically endangered North Atlantic right whales.

The lawsuit argues that fishermen voiced their concerns but received “virtually no attention or analysis” from government officials. It further states that BOEM failed to identify the proposed wind farm’s environmental, economic, social and cultural impacts, and failed to “consider alternative sites in an open, collaborative, public forum.”

However, BOEM says it has given consideration to comments received on the Environmental Assessment. In response to concerns raised by commercial fishing interests, BOEM has included a lease requirement for the lessee to develop a publicly available Fisheries Communications Plan and work with a Fisheries Liaison to facilitate communication with the fishing industry.

NOAA Fisheries Asking Boaters to Watch for Right Whales

December 2nd, 2016 — NOAA Fisheries is warning boaters to watch out for the critically endangered North Atlantic Right Whales.

The whales are now migrating south for the winter and to help protect them, NOAA fisheries has designated several Seasonal Management Areas along the U.S. East Coast.

In the areas, which include Block Island, the Ports of New York/New Jersey and the entrance to Delaware Bay, vessels greater than 65 feet in length must not exceed speeds of 10 knots, through April.

The purpose of the regulation is to reduce the likelihood of deaths and serious injuries to the endangered whales that result from collisions with ships.

Whales, sea turtles, seals: The unintended catch of abandoned fishing gear

September 29, 2016 — There are less than 500 North Atlantic right whales left in the world. And now, one less: This weekend, one of the 45-ton creatures was found dead off the coast of Maine, completely entangled in fishing line — head, flippers and all.

This was not an isolated incident.

In late June, an endangered blue whale wrapped in fishing gear was seen struggling off the coast of Dana Point in Southern California. Rescuers were unable to extricate it before it swam away. And earlier this month, rescuers unsuccessfully tried to free an entangled humpback whale near Newport. Spotters say they believe the humpback eventually found its way free of most of the gear, though they’re unsure if there’s anything still trapped in its mouth.

While any kind of fishing gear can be lost or abandoned at sea, gillnets, crab pots and traps are the most common types that continue to “ghost fish” — entrapping marine animals like whales, seals, sea lions and sea turtles.

Last year, the West Coast saw 61 whale entanglements — a record number that is nonetheless likely to be broken this year. So far in 2016, there have been 60 reports of entanglements as of late September. Why it’s happening is unclear. Researchers say there’s more derelict gear in the water today, and more reported sightings, but population numbers and migratory patterns of whales have also shifted.

What happens when a whale becomes entangled is grim.

“The gear is really, really heavy and when a whale comes in contact with it, it thrashes around to shed the gear,” says Kristen Monsell, attorney, Center for Biological Diversity. Sometimes that works; sometimes it entangles the whale even further.

More fishing gear entanglements jeopardize right whale’s recovery

August 31, 2016 — The ability of an endangered whale species to recover is jeopardized by increasing rates of entanglement in fishing gear and a resultant drop in birth rates, according to scientists who study the animal.

The population of North Atlantic right whales has slowly crept up from about 300 in 1992 to about 500 in 2010. But a study that appeared this month in the journal Frontiers in Marine Science said the number of baby right whales born every year has declined by nearly 40 percent since 2010.

Study author Scott Kraus, a scientist with the New England Aquarium in Boston who worked on the study, said the whales’ population suffers even when they survive entanglements in fishing gear. He said data suggest those entanglements have long-term negative physical and reproductive effects on them.

“They are carrying heavy gear around, and they can’t move as fast or they can’t feed as effectively,” Kraus told The Associated Press in an interview. “And it looks like it affects their ability to reproduce because it means they can’t put on enough fat to have a baby.”

Entanglements have surpassed ship strikes as a leading danger to right whales in recent years. Forty-four percent of diagnosed right whale deaths were due to ship strikes and 35 percent were due to entanglements from 1970 to 2009, the study said. From 2010 to 2015, 15 percent of diagnosed deaths were due to ship strikes and 85 percent were due to entanglements, it said.
