For Scientists, Chunks of Whale Earwax Can Be Biological Treasure Troves

January 26, 2017 — Whale earwax? Really? It’s weird on so many levels—that whales even have earwax, that someone thought to go looking for something like that, and that the Smithsonian’s National Museum of Natural History has stored not one, not ten, but about 1,000 samples of whale earwax plugs for well over 50 years.

And those samples, which not very long ago were gathering dust and some questions about their value, are now turning the scientific community on its (wait for it) . . . ear.

That’s because they are far more than the odd, quotidian and rather gross objects that they seem. We are learning now that samples of whale earwax are quite possibly unique in their ability to describe the life history of the longest-lived marine mammals, as well as give us a glimpse into a place and a time we cannot reach any other way. They are, in effect, physiological and ecological time capsules, and to research scientists who are trying to better understand the world’s oceans they are solid gold.

“It’s a good example of specimens which were collected for one purpose many, many years ago—the first ones were collected at the turn of the 20th century or so—and now as we find another way to interrogate these specimens, we’re able to discover that they have a whole other story to tell,” says Smithsonian researcher Charley Potter, who was the museum’s collection manager in the vertebrate zoology division until he retired in 2015.

50 NGOs critique MSC over bycatch

January 26, 2017 — A group of 50 non-governmental organizations (NGOs) has sent a letter to the Marine Stewardship Council (MSC) expressing their concerns about its certification of fisheries with high levels of bycatch.

The letter was authored by Kate O’Connell of the Animal Welfare Institute and Friederike Kreme-Obrock of Sharkproject Germany and signed by the heads of 50 nonprofits dedicated to environmental conservation, including dozens of groups dedicated to the protection and preservation of sharks, whales and dolphins.

“Many of our organizations have commented on fishery assessments under the MSC process, and over the years we have noted an apparent, and deeply worrying, lack of concern regarding the potential impacts on these species, as well as certain target species,” the letter said. “It is our view that many of the fisheries that have been assessed via the MSC certification process have not been subject to an adequate review of information available on bycatch of non-target species.”

The letter accuses the MSC of being subjective in interpreting evidence and in estimating the effects of a fishery’s impact on non-targeted species. It cites the absence of in-depth stock assessments for some species of bycatch as a problem under MSC Principle 2, which aims to maintain population levels of all species affected by a fishery at biological based limits.

Legal Proceedings Preserve Fishing Industry Rights as New York Wind Energy Lease Sale Proceeds

December 15, 2016 — The following was released by the Fisheries Survival Fund:

Last week, a group of fisheries organizations, communities and businesses filed suit against the Bureau of Ocean Energy Management (BOEM), seeking a temporary restraining order to delay today’s auction of leasing rights to the proposed New York Wind Energy Area. The suit also sought a preliminary injunction to prevent BOEM from executing any resulting wind energy lease.

The plaintiffs allege that BOEM did not adequately consider the effect on the region’s fishermen of a 127-square-mile wind farm off the coast of New York and New Jersey.

Subsequently, a scheduling agreement was reached between the parties that allows the court to take adequate time to deliberate carefully on the case’s important issues. The plaintiffs agreed to withdraw their motion for a temporary restraining order that would have delayed the scheduled auction. Although the auction is proceeding today, under BOEM’s final sale notice for the auction, the lease will not be final until further steps, as outlined in the sale notice, are completed.

On Monday, Judge Tanya Chutkan of the United States District Court for the District of Columbia set a court schedule on the plaintiffs’ motion to preliminarily enjoin BOEM’s execution of any lease resulting from today’s auction. The schedule concludes with a hearing in Federal court on February 8.

Under Judge Chutkan’s order, if the lease is ready to be executed before the court is able to rule on the plaintiffs’ preliminary injunction motion, BOEM must provide the court no less than 14 days notice. If that notice is provided, the preliminary injunction proceedings will be expedited.

The Fisheries Survival Fund, representing the majority of the U.S. Atlantic scallop industry, is the lead plaintiff in the case. The lease area includes documented scallop and squid fishing grounds, which serve 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.

Other organizations joining as plaintiffs include the Garden State Seafood Association and the Fishermen’s Dock Co-Operative in New Jersey; the Long Island Commercial Fishing Association in New York; and the Narragansett Chamber of Commerce and Rhode Island Fishermen’s Alliance.

Joining as plaintiffs are the City of New Bedford, Mass.; the Borough of Barnegat Light, N.J.; and the Town of Narragansett, R.I.

Also joining are three fishing businesses: SeaFreeze Shoreside, Sea Fresh USA and The Town Dock.

The real reason why you’re suddenly seeing whales in N.J. and N.Y. waters

November 28, 2016 — If you’ve spent any time walking the beaches or boating the ocean waters of New Jersey or New York in recent weeks, you’ve likely been treated to spectacle that has been a rarity in these parts for most of the past century or so: whales.

They’ve been seemingly everywhere.

Breaching just past the sandbars in Asbury Park.

Swimming past groups of surfers in Rockaway Beach.

Bumping into boats off Belmar.

And this week’s ultimate cetacean sensation: a humpback whale swam up the Hudson River for a photo op in front of the George Washington Bridge.

Besides inspiring a chorus of oohs and aahs, the increase in sightings is adding a blubbery new wrinkle to a raging debate over a far smaller fish: the Atlantic menhaden. It’s the menhaden, also known as “bunker” — clumsy, multidinous, slow swimming virtual floating hamburgers — that those whales are chasing.

Even as the whales were gulping down bunker along the coast of New Jersey, the ASMFC has been pushing the commercial quotas back up closer to pre 2012 catch levels. Last year, the catch limit was raised 10 percent, with the ASMFC citing data that showed bunker were not being overfished.

And, then, three weeks ago, the council voted to raise the commercial catch limits another 6.5 percent.

That move has been cheered by commercial fishing operations who argue the limits were never necessary and simply jeopardized an industry that employs hundreds of people from New Jersey to Virginia, where the largest menhaden processing operation, Omega Protein Corp, is located.

“The fact that there’s a lot of fish around has nothing do with reducing these quotas,” said Jeff Kaelin, spokesman for Lund’s Fisheries, a Cape May commercial fishing company that sells bunker as lobster bait. The increased number of whale sightings is simply the result of smaller fish growing to a larger size due to “environmental conditions.”

“The stock was not overfished,” he said. “It’s never been.”

Kaelin said the 20 percent coast-wide reduction translated into a roughly 50 percent cut for New Jersey companies that harvest bunker, because it shut down the fishery early in the year and put the state’s crucial fall harvest off limits.

“If the science says we need to cut back we will, but in this case we feel very strongly that we’re underfishing the stock,” he said.

NEW YORK: Why researchers think humpback whale swam up the Hudson

November 22, 2016 — The whale spotted in the Hudson River Thursday in Friday was likely led there by food, the head of a local whale research group said.

Photos of the humpback whale showed it “lunge feeding,” said Paul Sieswerda, president of Gotham Whale.

“That’s when they come up and break the surface and consume these bait balls of menhaden,” he said.

Predators drive menhaden, sometimes known as bunker fish, into tight balls. This allows whales to open their mouths and eat them all at once.

New Lobster Trap Technology Could Reduce Whale Entanglements

November 14, 2016 — WOODS HOLE, Mass. — More and more whales are becoming snarled in fishing gear, often dying slow, painful deaths.

Two Woods Hole Oceanographic Institution (WHOI) engineers have invented a lobster trap device that they say could help whales avert entanglements and, at the same time, might allow currently restricted waters to be safely reopened for lobster fishing.

In New England’s offshore lobster fishery, long vertical ropes or “lines” connect the traps on the bottom to floats on the water’s surface, so fishermen can locate their trawls and drag them back up.

The new device is called the “on-call” buoy and floats near the bottom attached to lobster traps.

Falmouth researchers discover new information about whale songs

November 7, 2016 — A group of Falmouth-based researchers has gained new insight into the songs of the humpback whale.

When a whale sings, physical vibrations can be felt around the animal. A team of researchers from the Woods Hole Oceanographic Institution found that these vibrations, known as particle velocity, can be felt much farther away than originally thought.

“Particle velocity is kind of the long bass that you feel when a car is approaching you. You can hear the sound far away, but you can also feel the vibration,” said Aran Mooney, a Woods Hole biologist. “But sound doesn’t travel as well in air as it does in water.”

In a paper published Wednesday in the journal Biology Letters, the Woods Hole team detailed their findings from studying a group of humpback whales off the coast of Maui. Mooney said they measured vibrations from about 200 meters away from the whales, but believe they could be felt as far as one kilometer away.

The Secret Life of Krill

October 19, 2016 — SYDNEY, Australia — On an August morning aboard the Nathaniel B. Palmer research vessel floating at the bottom of the world, Christian Reiss was listening for acoustic signals bouncing off krill, a pinkish, feathery-limbed crustacean that is the lifeblood of the Antarctic ecosystem.

It was the last month of the Southern Hemisphere winter, and conditions were good: There was no thud from sea ice pancakes bumping together to distort his tests in the clear waters of the South Shetland Islands, about 500 miles south of Cape Horn.

Dr. Reiss, an oceanographer with the National Oceanic and Atmospheric Administration, and his team were studying where krill live in winter.

Low levels of sea ice gave them access to bays that in previous winters were closed. They wanted to know if a lack of sea ice, where krill gather to feed off the algae that live on the underside, was threatening the ocean’s largest biomass. Krill form schools that can be miles long and miles deep.

Whales, sea birds, penguins, squid and seals all feed off krill. And they compete with commercial fisheries in the same waters, who sell the tiny creatures to be used as fish food or to make omega-3 fish oil for human use.

NOAA: Fishing gear killed endangered right whale

October 3, 2016 — ELLSWORTH, Maine — Entanglement in a morass of fishing gear killed an endangered right whale spotted off Boothbay Harbor last week and brought ashore in Portland last weekend for a necropsy, according to the National Oceanic and Atmospheric Administration

Speaking on Monday, Jennifer Goebel, a spokeswoman for NOAA’s Greater Atlantic Region in Gloucester, Mass., said scientists from the fisheries service had determined that “chronic entanglement was the cause of death” of the 45-ton, 43-foot-long animal.

Goebel also said that the New England Aquarium had identified the whale as No. 3694 in its North Atlantic Right Whale Catalog. According to Goebel, the whale was a female, believed to be about 11 years old, with no known calves.

The whale was first sited by researchers in 2006. Since then, the whale has been sited along the Atlantic Coast 26 times, most recently off Florida in February of this year.

According to Goebel, passengers on a Boothbay Harbor-based whale watching boat spotted the dead whale on Friday floating about 12 to 13 miles off Portland wrapped in fishing gear. Rope was reportedly wrapped around the whale’s head, in its mouth and around its flippers and its tail.

OPINION: Humpback whales a welcome sight off NJ coast

October 3, 2016 — Beachgoers in the Monmouth County town of Manasquan were thrilled in late August when a humpback whale appeared offshore. For two hours, it breached, spouted, slapped its fins on the water and waved them in the air.

Of course, the humpback wasn’t there for entertainment. It was simply having a long lunch, feeding on abundant small fish in the water.

Humpback whales are making a comeback. Fishermen in the New York Bight — the triangular corner of ocean between Montauk Point, Long Island, and Cape May — are seeing them regularly.

On September 6, a few days after the Manasquan sighting, the National Marine Fisheries Service announced its decision to remove most humpback whale populations from its endangered species list. Once depleted by commercial whaling, humpbacks had been on the list since 1970.

Humpback whales are divided into 14 distinct global populations. The population along the East Coast of the United States, which breeds in the Caribbean and migrates north for feeding, is considered stable and not at risk. Four endangered populations remain, including one that breeds off of Central America and migrates up the coasts of California and Oregon.
