NOAA: Drone technology aids whale research off Hawaii

July 29, 2016 — HONOLULU — Federal researchers returning from a 30-day expedition to study whales and dolphins around the Hawaiian Islands said Thursday they are looking for clues to help sustain healthy populations of the marine mammals.

National Oceanic and Atmospheric Administration scientists told reporters that gathering data on the animals is often difficult, especially around the windward coasts of the Hawaiian Islands.

The researchers worked from a large ship, instead of using their normally small survey boats, and explored the coasts of the main Hawaiian Islands where wind conditions and severe weather make it difficult to navigate and remain at sea for extended periods of time.

The team also used a hexacopter drone to photograph the whales and dolphins, something they have never done before in this region.

Using drones allows researchers to get better images of groups of whales because they are not disturbed by the approaching boat, said NOAA’s Erin Oleson, who led the expedition.

The vantage point of the drone also allowed them to more accurately count the number of individuals in a pod, including mothers and calves that sometimes stay underwater. The number of calves helps researchers gauge the whale’s reproductive health. The perspective also allows the scientists to get more accurate size estimates for individual whales.

New and rare whale species identified from carcass found in Pribilofs

July 27, 2016 — A stroll on the beach of a remote Bering Sea island two years ago has produced a scientific breakthrough — the discovery of a previously unidentified species of beaked whale that dwells in the deep waters of the North Pacific Ocean.

The conclusion, described in a study published in the journal Marine Mammal Science of the California-based Society for Marine Mammalogy, stems from the 2014 discovery of a beached whale carcass by a local monitoring program called Island Sentinel. Karin Holser, a teacher on St. George Island in the Pribilofs, alerted authorities, and Michelle Ridgway, a Juneau-based biologist involved with a Pribilof science camp, responded quickly.

“She was the one who said, ‘This looks like a Baird’s beaked whale, but it doesn’t,'” said Phillip Morin, a research molecular geneticist with the National Oceanic and Atmospheric Administration and lead author of the new study.

The whale was about two-thirds the size of a Baird’s beaked whale, which typically grows to 35 or 40 feet, Morin said. It was clearly not a juvenile, as its teeth were worn and yellow, “so they were not baby teeth,” he said. Its skull had a distinct slope and its dorsal fin was different from that of the typical Baird’s beaked whale.

Tissue samples were sent to the Marine Mammal and Turtle Division of NOAA Fisheries’ Southwest Fisheries Science Center in California, where Morin works and where the world’s most extensive collection of cetacean tissues is kept. The whale’s skull was sent to the Smithsonian Institution in Washington — and students from the Pribilofs visited the lab there to take part in the examination.

DNA analysis showed it was a species different from the 22 previously known species of beaked whales in the world and the two known to swim in the North Pacific.

Whales popping up in Long Island Sound for second year

July 26, 2016 — NORWALK, Conn. — For the second year in a row, whales have been spotted in the Long Island Sound, with sightings all the way in near Fairfield County. But why?

According to Joe Schnierlein, with the Maritime Aquarium in Norwalk, “They’re here for food. This is a smorgasbord for them.”

He’s referring to a fish called menhaden, also known as buffers.

“Right now, the entire western end of the Sound is loaded with them,” Schnierlein explained.

Navy’s submarine hunts are too disturbing for marine life, California court rules

July 20, 2016 — They came as a wave, some 150 to 200 melon-headed whales churning into Hawaii’s Hanalei Bay like a single mass. It was a strange sight for the Kauai islanders to behold. Melon-headed whales live in the deep ocean, feasting on squid. But here they were, swimming in the shallows no more than 100 feet from shore.

Over the course of July 3 and 4, 2004, volunteers and rescuers shepherded the animals back to sea, according to the National Oceanic and Atmospheric Administration’s account of the mass stranding. The Washington Post reported at the time that it was the largest event of its kind in 150 years of Hawaiian history. Almost all the whales made it back out into the open water. But not the entire pod.

A young calf, split off from the rest of the herd, perished the next day.

A year later, 34 whales died when they were stranded at North Carolina’s Outer Banks. Three years after that and half the world away, 100 melon-headed whales were again stranded en masse, this time on the shores of Madagascar. The reasons why whales beach themselves are not always clear — strandings have been likened to car crashes in that the causes are myriad but the conclusion is never good. With the melon-headed whales, however, something was different. The events were unusual enough, and involved such large numbers, to prompt scrutiny. In both cases, a prime suspect emerged: sonar.

Controversy over these sound waves continues today. And in the latest skirmish over oceanic noise pollution, a victory went to the whales. On Friday, a federal appeals court in San Francisco ruled that the Navy violated marine mammal protection laws, reversing a lower court’s decision that allowed military vessels to use a type of loud, low-frequency sonar approved in 2012.

Predators coming closer to Brooklyn beaches, experts say

June 28, 2016 — The sharks are circling!

A bumper crop of bunker fish churning along the coast is drawing the ocean’s greatest predator closer than ever to Brooklyn’s beaches, anglers and naturalists say.

“That population (bunker) is very high along our shore, and that is bringing sharks and whales much closer to shore, bringing the predators much closer to the beach,” said captain John Calamia of Whatta Catch.

Cutback mulled for herring catch

June 23, 2016 — PORTLAND, Maine — Federal regulators are considering a slight cut to commercial fishermen’s catch limit for Atlantic herring, a fish that is important both to the industry and the ocean’s food web.

The small fish gather in schools that can number in the millions, and are a critical food source for bigger fish, seals and whales. They also are important to humans as food and bait.

The National Marine Fisheries Service might reduce the herring catch limit by about 3 percent to slightly less than 105,000 metric tons. The limit was a little less than 108,000 metric tons for the 2013 to 2015 period; any new limit would apply to the years 2016 to 2018.

The proposal is up for public comment until July 21.

NOAA Announces Proposals to Expand Flower Garden Banks National Marine Sanctuary

June 9, 2016 — Building on more than 30 years of scientific studies, including numerous reports released in the last decade and in the aftermath of the 2010 Deepwater Horizon oil spill disaster, NOAA today announced a proposal to expand Flower Garden Banks National Marine Sanctuary to protect additional critical Gulf of Mexico habitat.

The plan lays out five expansion scenarios, ranging from no expansion of the 56-square-mile sanctuary, to one bringing it to a total of 935 square miles. In NOAA’s preferred scenario, the sanctuary would expand to 383 square miles to include 15 reefs and banks that provide habitat for recreationally and commercially important fish, as well as a home to 15 threatened or endangered species of whales, sea turtles, and corals.

“These habitats are the engines of sustainability for much of the Gulf of Mexico and are critical to fish such as red snapper, mackerel, grouper and wahoo, as well as other protected species,” said John Armor, acting director, NOAA’s Office of National Marine Sanctuaries. “The proposed expansion also advances NOAA’s mission to conserve and manage coastal and marine ecosystems and resources that help sustain local communities and America’s economy.”

Whale-finding phone app grows in use, helps mariners steer clear

May 27, 2016 — PORTLAND, Maine — With summer whale watching season fast approaching, conservation advocates and government agencies who want to protect whales say a mobile app designed to help mariners steer clear of the animals is helping keep them alive.

The Whale Alert app provides a real-time display of the ocean and the position of the mariner’s ship, along with information about where whales have been seen or heard recently. It also provides information on speed restrictions and restricted areas, and recommends routes shippers can take to avoid endangered species such as the blue whale and the North Atlantic right whale.

New England whale watching companies are gearing up for summer, and more than a quarter of the entire North Atlantic right whale population visited Cape Cod Bay this season. That means conditions are perfect to get more mariners and the public on board with protecting whales, said Patrick Ramage, whale program director for the International Fund for Animal Welfare.

Andy Hammond, of Martha’s Vineyard, is one such mariner. He has used the tool aboard pilot boats to avoid whales in Boston Harbor.

Scientists, fishermen plot ways to prevent whale entanglements

May 25, 2016 — PORTSMOUTH, N.H. — Nette Leverman was reading from a sheaf of papers she held in her hand, detailing the interactions between whales and fishermen in Greenland, where she is a population biologist.

Humpback, minke, fin and bowhead whales were getting caught in fishing line and nets in the waters off the country’s coast. It’s a familiar refrain, heard over and over Monday, the first day of a four-day international workshop on large whale entanglements.

“We’ve known for decades about this problem, yet solutions to it remain elusive,” said Tim Werner, a senior scientist at the New England Aquarium, and one of the workshop’s organizers.

Governments and fishermen around the world are feeling the strain from an increasing numbers of whales being snared in fishing gear as some whale species rebound and as the amount of gear in the water increases for fishing, aquaculture and other uses.

Woods Hole Researchers ‘Listen’ to the Ocean Floor

May 23, 2016 — WOODS HOLE, Mass. — Listening to the noise of the deep sea.

That’s the intent as researchers with the Northeast Fisheries Science Center, based at the Woods Hole Oceanographic Institution, recently placed a handful of recording devices along the ocean floor from George’s Bank to New Jersey to listen to the sounds of whales, dolphins and other marine life.

It’s part of a national effort to establish a network to monitor long term changes in ocean noise.
