Recent Right Whale Deaths Have Scientists Worried

July 7, 2017 — The deaths of six North Atlantic right whales in the Gulf of St. Lawrence last month have raised alarms among whale biologists who fear for the future of one of the rarest whales on the planet.

Robert Kenney, a marine mammal expert at the University of Rhode Island’s Graduate School of Oceanography, called the unexpected deaths “a major concern” because the population of right whales totals fewer than 500 animals and their numbers have been declining since 2011. The dead whales represent more than 1 percent of the population.

While the deaths raise many questions, one of the first, according to Kenney, is what were they doing in the Gulf of St. Lawrence in the first place?

“Right whales go to the same places to feed every year — the Great South Channel, the Bay of Fundy, the Nova Scotia shelf — feeding grounds they probably learned from their mothers in their first year of life,” said Kenney, who manages the sighting database for the North Atlantic Right Whale Consortium. “But recently they seem to be wandering farther afield. If there’s not enough food where they traditionally feed, they go to other places. That’s what we think is going on.”

What caused the deaths of the six whales in the Gulf of St. Lawrence — the water body surrounded by Newfoundland, Quebec, Nova Scotia and New Brunswick — is uncertain. Preliminary results of necropsies on three of the animals showed evidence of blunt trauma from ship strikes on two of the whales and fishing gear entanglement on the third. But a news release from Canada’s Marine Animal Response Society said other problems that “may have predisposed these animals to this trauma cannot be ruled out at this stage.”

Increased whale sightings in New York City waters a sign of cleaner waters

July 6, 2017 — New video shows a diver off the coast of Tasmania coming face to face with a whale recently in a once-in-a-lifetime encounter.

But you don’t have to travel to Australia to see these marine giants–they’re now in the waters off New York City.

Though the Hudson River was once a national symbol for pollution, humpback whales have become a more common sight around New York and New Jersey, reports CBS News correspondent Jeff Glor.

A whale sighting may look like an acrobatic display with its fluke set against the city’s skyscrapers, but they’re actually lunge feeding–attacking fish called menhaden.

“One of the things that brings everything together is this food chain,” said Paul Sieswerda, the president of the non-profit Gotham Whale. He says menhaden are thriving because the water is cleaner.

NOAA Establishes Voluntary Speed Restriction Zone South of Nantucket

June 28, 2017 — A voluntary speed restriction zone about 15 miles south of Nantucket has been established by the National Oceanic and Atmospheric Administration’s fisheries division.

It comes after three right whales were spotted in the area recently.

According to researchers, there are only about 400 North Atlantic right whales still in existence.

Those who approach a right whale closer than 500 yards will be in violation of federal and state law and could lead to criminal charges.

Offshore Wind Turbines Blamed For Killing Family Of Whales

May 23, 2017 — Marine environmental experts blame offshore wind turbines for the deaths of three minke whales that washed up on British beaches, The Times reported Monday.

Wildlife experts claim that the noise generated by wind turbines affected the sonar that whales use to navigate, causing them to beach themselves. There are several commercial offshore wind farms close to where the whales beached themselves.

“My personal opinion is that it could be a consequence of wind farms and the amount of sand in the water,” John Cresswell, chairman of the Felixstowe Volunteer Coast Patrol Rescue Service, told The Times. “If you stop the boat off the coast you can feel the vibrations and hear the noise.”

The U.K. coastguard received reports of a minke whale calf that had become separated from its mother Friday evening. By the next afternoon, it had been found dead at the mouth of the River Ore, and its mother washed up near Felixstowe. On Sunday, another dead adult whale surfaced, indicating that an entire family could have been killed.

“There are studies that show that the sounds created by the operational noise of the turbines create vibrations under that may in fact disorient marine mammals like whales,” Bonnie Brady, director of the Long Island Commercial Fishing Association who regularly discusses the impacts of noise on marine mammals, told The Daily Caller News Foundation. “In the case of what looks like this mother and calf, they go on the wrong path and end up disoriented then beaching themselves. The sound kills.”

Mass Die-Off of Whales in Atlantic Is Being Investigated

April 28, 2017 — Humpback whales have been dying in extraordinary numbers along the Eastern Seaboard since the beginning of last year. Marine biologists have a term for it — an “unusual mortality event” — but they have no firm idea why it is happening.

Forty-one whales have died in the past 15 months along the Atlantic coast from North Carolina to Maine. In a news conference on Thursday, officials from the National Oceanic and Atmospheric Administration Fisheries said that they had not identified the underlying reason for the mass death, but that 10 of the whales are known to have been killed by collisions with ships.

The agency is starting a broad inquiry into the deaths.

These whales “have evidence of blunt force trauma, or large propeller cuts,” said Deborah Fauquier, a veterinary medical officer at the agency’s Office of Protected Resources. These collisions with ships were “acute events,” Dr. Fauquier said, and were being treated as the “proximate cause of death.”

Dr. Fauquier said that the number of whale strandings was “alarming,” and that she hoped the investigation might give a sense of what kind of threat this presents to this population of humpback whales and those around the world.

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.”
