NOAA investigates ‘unusual’ whale deaths

April 27, 2017 — The National Oceanic and Atmospheric Administration Fisheries says the deaths of 41 humpback whales dating back to last year in the waters between North Carolina and Maine will have “a focused, expert investigation into the cause.”

NOAA made the announcement Wednesday, noting that the deaths constitute an “unusual mortality event.” Under the Marine Mammal Protection Act, an unusual mortality event is defined as “a stranding that is unexpected; involves a significant die-off of any marine mammal population; and demands immediate response.”

NOAA is expected to release more information on the investigation Thursday.

Despite recovery, humpback whales still suffer from ship strikes

April 27, 2017 — Decades after most countries retired their harpoons, whales still face threats from fishermen, ships, and coastal pollution. But one species that seemed to have overcome these challenges was Megaptera novaeangliae, better known as the humpback whale.

Heavily hunted by the early 20th century, an international whaling moratorium and protection under the US Endangered Species Act (ESA) gave humpbacks the breathing space they needed to recover.

From 1986 to 2008, the whales’ numbers rose to 60,000 worldwide, and their status on the International Union for the Conservation of Nature’s “Red List” improved from “Endangered” to “Least Concern.” By last September, the National Oceanic and Atmospheric Administration (NOAA) announced that nine of the 14 distinct humpback populations no longer warranted ESA protection. Last year, one was even spotted in the Hudson River.

But a study published Tuesday in the journal Marine Mammal Science puts an asterisk on this progress. Close to shore, ship collisions threaten several species of whales, and these strikes may be greatly underreported for one humpback population in the Gulf of Maine.

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.”

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.

Right Whale Found Dead in Cape Cod Bay

April 17, 2017 — The following was released by NOAA:

On Thursday, April 13, a dead North Atlantic right whale was reported around 11:30 a.m. near Barnstable by researchers conducting right whale surveys in Cape Cod Bay. The United States Coast Guard provided assistance by towing the carcass to a landing site in Sesuit Harbor. Researchers then transported it by trailer to a necropsy site in Bourne for a complete examination. The necropsy logistics were organized by the International Fund for Animal Welfare and overseen by NOAA Fisheries. The examination team was led by Bill McLellan from University of North Carolina Wilmington and included stranding response experts from Woods Hole Oceanographic Institution, Virginia Aquarium & Marine Science Center, Marine Mammals of Maine, Atlantic Marine Conservation Society, Center for Coastal Studies, New England Aquarium, Massachusetts Division of Fish and Wildlife, and University of New Hampshire. 

“It’s really worrisome to know that another young right whale has died in our waters,” said Misty Niemeyer, Necropsy Coordinator for the International Fund for Animal Welfare. “As an endangered species of approximately 500 individuals, every animal is important for the survival of the population. We need to learn as much as we can from her tragic death and gain valuable insight in hopes to further protect the species.”

The young whale was a female, and was approximately 27 feet long. She has been identified as a one-year old offspring of Eg#4094 from the North Atlantic Right Whale Catalog born in 2016.

“It’s very difficult to lose one of our endangered North Atlantic right whales, but it’s important for us to use this tragedy as a means to stay vigilant in our efforts to recover the species,” says Kim Damon-Randall, assistant regional administrator for protected resources at NOAA Fisheries Greater Atlantic Region. “We’ll analyze the samples taken from the whale for disease, biotoxins, histology, genetics, and life history information. This will provide a glimpse into the life and death of this whale, which will contribute to our efforts to protect other whales in the population.”

Preliminary findings of bruising were consistent with blunt trauma. There was no evidence of entanglement. Final diagnosis is pending ancillary laboratory tests that can take weeks or months. There have been a record high number of endangered right whales observed in Cape Cod Bay over the past few weeks, and over 100 whales were observed last weekend during an aerial survey research project. We urge vessels of all sizes to keep a close look out for right whales at all times and to travel slowly to help prevent injury to both whales and people. Right whales skim the water surface to feed or hang just below the surface and are difficult to see. They can grow to 50 feet in length and weigh up to 55 tons, so they are large animals that need space. Look for blows, ripples in the water, and patches of plankton–these are often signs that whales are in the area. Vessels and aircraft are required to maintain a distance of 500 yards from right whales.  We encourage everyone to take this opportunity to view the right whales from local Cape Cod beaches, including Race Point Beach. More information on right whales, and how to report sightings, is on NOAA Fisheries Greater Atlantic Region’s website. 

Whale show returns to California’s coast, and it’s amazing

April 14, 2017 — Whale breath smells like fermented Brussels sprouts.

When you’re on the sea and pick up a whiff of that unmistakable aroma, even if only for a moment, it can feel like a 110-volt jolt.

It can mean only one thing: They’re close … real close.

For a few seconds one spring day out of Pillar Point Harbor near Half Moon Bay, that smell filled the air around us. We were in a Zodiac inflatable in 60 feet of water off Moss Beach. My fishing partner, Jim McDaniel, turned to me and said, “Do you smell that?”

Before I could answer, a gray whale emerged 30 feet from us, its back jutting through the surface, and then let loose from its blow hole. With a loud whoosh, a misty stream of water rocketed into the air.

The shock of the whale so close — it felt as if he could have capsized us — probably cleared all the cholesterol out of our bloodstreams.

Right on schedule, the whales are back, same time, same place.

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.

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.
