It’s a Boy! Right whale calves spotted in Cape Cod Bay

April 5, 2017 — On Monday, April 3, the Center for Coastal Studies (CCS) right whale aerial survey team spotted a right whale mother and calf pair in the north end of Cape Cod Bay between Race Point and Marshfield. This sighting came just hours after researchers from the Northeast Fisheries Science Center identified a different mother / calf pair observed in the Cape Cod Canal.  These are the first sightings of the new calves of the year in Gulf of Maine waters.

The male calf spotted by the CCS team is the offspring of a whale named Pediddle, a whale at least 39 years old that was first identified in 1978 and first seen in Cape Cod Bay in 1979. The new calf is Pediddle’s eighth documented by scientists; her last calf was born in 2009.

“During the sighting the mom was subsurface feeding while the calf was rolling and tail slapping,” said Alison Ogilvie, an aerial observer for the Center’s Right Whale Ecology Program. “Mom and calf looked very healthy considering they’ve just completed a more than 800 mile migration from the calving grounds off Georgia and Florida.”

The aerial survey team also observed and photographed 71 other individual right whales in Cape Cod Bay on Monday, the most seen so far this season.

MASSACHUSETTS: Right whales return to Cape Cod Bay

January 24, 2017 — Two rare and critically endangered North Atlantic right whales were spotted in Cape Cod Bay, the first of the year seen in the area, according to the Center for Coastal Studies in Provincetown.

The center’s research vessel Shearwater spotted the two whales in the bay five miles south of Provincetown Harbor on Jan. 17. On Thursday, center officials say they saw five right whales in the same area.

There are only an estimated 524 right whales in the world, according to the center. They come to the bay every winter due to the high concentrations of microscopic zooplankton there, which is a food source for the whales.

The whales’ presence in the bay warrants caution, according to the center.

Tropical Fish in Cape Cod Waters: “The More You Look, the More You See.”

October 24th, 2016 — Gulf Stream Orphans are appearing in our region. That’s not the name of a rock band, and they’re not unaccompanied children. Gulf Stream Orphans is the research term for Caribbean fish that show up in our Cape Cod waters, and scientists are looking to see if their numbers are increasing.

Owen Nichols, Director of Marine Fisheries Research at the Center for Coastal Studies, joins us to talk about these fish, what types they represent, and new efforts to understand whether they’re appearing more often, or simply being noticed more now that researchers are looking for them.

Endangered Right Whale Season Winds Down in Cape Cod Bay

May 10, 2016 — PROVINCETOWN, Mass. — The 2016 North Atlantic right whale season is winding down and researchers from the Center for Coastal Studies in Provincetown are reporting a large turnout in the area.

The center conducts multiple aerial surveys each week from December through May to provide data to local, state and federal managers of the critically endangered species which population is estimated to be around 500.

More than 25 percent of the species estimate population visited Cape Cod Bay this season, including six mothers and their newborn calves.

“It’s once again an indication that Cape Cod Bay is central to the future of the species,” said Charles “Stormy” Mayo with the Center for Coastal Studies.

The whales come to the bay during this time as there is an abundance of food.

Boat operators warned to steer clear of whales

April 25, 2016 — State environmental officials this week issued a “high risk” warning to boat operators asking them to stay alert after five North Atlantic right whale mother and calf pairs were spotted foraging on plankton in Cape Cod Bay.

According to the advisory from the Massachusetts Division of Marine Fisheries, the highly endangered whales were seen feeding Thursday in the western part of the bay during an aerial survey conducted by researchers from the Center for Coastal Studies.

“Given their behavior and the proximity to vessel traffic, the situation presents a high risk of vessel collision to a sensitive and important segment of the right whale population,” according to a statement.

Right Whale, Wrong Place

April 20, 2016 — Whale watchers spent the day yesterday in Nahant looking for Mr. Right.

A wayward North Atlantic right whale made a splash just off the shore for most of the afternoon.

The endangered species is known to hang out near Cape Cod Bay this time of year, according to Charles “Stormy” Mayo, senior scientist at the Center for Coastal Studies in Cape Cod and director of the right whale ecology program.

“Anytime a few whales go up the shore it’s really a special thing and a rare occasion,” he said. 
“Every time, in the case of the right whales, their travel depends on the concentration of food; they’re grazers.”

Mayo added he thinks the whale frolicking off Nahant is likely to return to the Cape, where there is the highest concentration of North Atlantic right whales. Fewer than 500 are thought to exist.

Gloucester Daily Times: Right whale population continues to rebound

March 15, 2016 — Here’s a bit of good news about the ocean environment: Right whales, once thought to be on the brink of extinction, are returning to Cape Cod Bay in record numbers.

And it’s not a one-time event. Marine scientists say nearly half of the estimated right whale population of 500 has been spotted in the bay over the past few years. It’s a huge leap from years past, when researchers counted themselves fortunate to see more than a couple dozen visiting the bay in search of food.

“It’s rather extraordinary and somewhat mind-blowing,” Charles “Stormy” Mayo, a senior scientist and director of right whale ecology at the Center for Coastal Studies in Provincetown told the Associated Press.

“There has been a huge pulse in numbers in the past few years,” said Amy Knowlton, a scientist with the New England Aquarium’s Right Whale Research Project.

Habitat Designation Key to Right Whale Recovery

February 2,2016— There is reason to be optimistic that the recent move by the federal government to expand the protected habitat of the North Atlantic right whale will protect the endangered species without harming its equally at-risk ocean neighbor, the commercial fishing industry.

The mammals and fishermen have historically been at cross purposes. The whales were given their name because they were the “right” whale to kill, thanks to their proximity to shore and the fact that they floated when dead, allowing them to be easily towed behind a whaler. The modern fishing industry no longer targets the whales, of course, but the mammals can get tangled in lost or discarded fishing line and gear, which often leads to their death.

 Commercial whaling decimated the once-thriving right whale species in the late 1800s and early 1900s. Just a few decades ago, only 300 or so remained. Over the last three decades, however, conservation efforts have brought the number to around 500.

“We have made progress,” David Gouveia, the marine mammal and sea turtle conservation coordinator for the Greater Atlantic Region of the National Marine Fisheries Service, told the Associated Press. “We are on a positive trajectory but there is still plenty of work to be done.”

Last month, the National Oceanic and Atmospheric Administration announced it was expanding its list of right whale habitat, adding calving grounds off the coast of the Carolinas and feeding grounds off New England. The move designates more than 30,000 square nautical miles as critical.

The designation, set to go into effect at the end of the month, means projects that require federal permits — such as dredging or building oil rigs or wind farms — will now be measured at least in part on how they affect the whales’ habitat.

“It’s a very important move,” Charles “Stormy” Mayo, director of right whale habitat studies at the Center for Coastal Studies in Provincetown, told the Boston Globe. “It’s pretty tough to put a small box around a wild animal, especially a whale that travels many thousands of miles each year of its life. … What we have here is an adjustment that recognizes the wide use of the environment that supports these whales.”

The measure is not expected to affect fishing or lobstering operations. Both industries have scrapped with the federal government in the past over how best to help the whales rebound while keeping hundreds of small businesses afloat. Those negotiations have often been complicated by lawsuits from environmental groups looking to force a solution, generally at the expense of fishermen.

“It’s a very real fear among the fishing industry,” Patrice McCarron of the Maine Lobstermen’s Association told the Bangor Daily News. “The right whale issue has been a very litigious issue — period.”

Fishing for a solution for endangered right whales

December 29, 2015 — Sometimes technology solves a problem, sometimes it makes it worse.

When researchers at the New England Aquarium and the Center for Coastal Studies in Provincetown examined ropes recovered from whales entangled in fishing gear from 1994 to 2010, they found that entanglements for North Atlantic right whales, the world’s most endangered great whale species, accelerated dramatically from 1993 to 2010, in both frequency and in the severity of the entrapment.

The culprit, scientists believe, is a new type of rope known as Polysteel, that rope manufacturers began making and marketing to fishermen and others in the marine trades as being 40 percent stronger and more durable than other synthetic ropes. Plus, the lobster industry also shifted from wood to wire traps that allowed them to use heavier gear and for the pots to stay in the water through the winter, increasing the likelihood of interaction with whales.

Even though fishermen already employ weak links designed to break and separate the line from the buoy when a whale pulls on it, researchers found the lines themselves were still doing a lot of damage.

“It was a huge change,” said Amy Knowlton, the lead author of the study and a research scientist with the New England Aquarium working to reduce the risk of whale entanglement and death from fishing gear and lines. Scientists put the number of North Atlantic right whales that can be lost due to human causes at less than one per year, if the population is going to increase and avoid extinction. The National Marine Fisheries Service has calculated that 3.25 right whales per year either died or were severely injured between 2007 and 2011 by being caught up in fishing gear and lines. The agency estimates that 83 percent of the right whale population shows scarring from fishing gear.

Study: Ropes that break more easily could save some whales

December 15, 2015 — BOSTON (AP) — A study published in a scientific journal says life-threatening whale entanglements could be reduced by using ropes that break more easily under the force of the enormous animals.

Whales become entangled in commercial fishing gear almost every week along the East Coast of the United States and Canada. A coastal study in conservation biology examined ropes retrieved from live and dead whales entangled in fishing gear from 1994 to 2010.
