Whale research to highlight changes in gulf

November 2, 2017 — BAR HARBOR, Maine — Upcoming new research into the feeding habits of baleen whales in the Gulf of Maine – one of the fastest-warming bodies of water on the planet – could shed light on impacts of climate change on oceans worldwide.

The study of whale foraging ecology will be undertaken by members of College of the Atlantic’s Allied Whale marine mammal research program, in partnership with Cetos Research Organization, during a five-year project beginning in spring 2018.

Paired with data from a similar Allied Whale study done before temperatures began rising so dramatically in the gulf in 2004, this new research will give scientists their first broad picture of how the ocean’s top predators are adapting to a rapidly changing environment.

“The warming gulf has the potential to radically affect prey structure, and we have the control data from before the warming started to go by,” said Allied Whale Director Sean Todd, the Steven K. Katona Chair in Marine Science at COA and a principal investigator on the project.

The Lost Whaling Fleet is finally found

January 18, 2016 — During the summer of 1871, a mini-armada of American whaleships hunting for bowhead whales in the Arctic Ocean gambled against the weather, and lost. As the fleet sailed north, the temperature plummeted, and unrelenting winds pushed massive ice floes toward the coast, which first pinned the whaleships in place, and then began crushing their hulls. In the end, 32 whaleships were destroyed in what became the greatest single disaster in the history of American whaling.

For nearly a century and a half, the remains of those ships were hidden from view, but no longer. This past summer, archaeologists from the National Oceanic and Atmospheric Administration, using sonar and sensing technology, found the hulls of two whaling ships in the same area where the disaster occurred. These ships, whose discovery NOAA only recently made public, are almost certainly part of that ill-fated fleet.

The story of the so-called Lost Whaling Fleet is one of the most dramatic in America’s long and turbulent history of whaling. Since the mid-1800s, American whalers had been pursuing bowhead whales in the Arctic. These massive creatures, which can grow more than 60 feet long and weigh up to 100 tons, yielded as much as 300 barrels of oil, widely used for lighting.

But by the time the whaling fleet headed north in 1871, the whale oil market had been virtually eliminated. After the discovery of petroleum in 1859, an ever-increasing amount of that “black gold” was pumped from the ground and refined into a flood of cheap kerosene that ultimately displaced whale oil and other illuminants.

What the whalers of 1871 wanted from the bowheads was not oil, but the hundreds of strips of baleen that were hanging down from the roof of their mouths. Whales use this keratinous material, which when viewed from the side resembles a comb with hairy fringes on the inner edge, for feeding. Baleen was valuable because it was made into hoops for hooped skirts, and stays for stomach-tightening and chest-crushing corsets, which were fashionable at the time. Bowhead whales were especially prized, because they had the longest baleen of any whale, reaching lengths of nearly 14 feet.
