‘Rolls-Royce’ of shark cameras can extend to turtles, whales, seals and squid for ocean’s big picture

Boston Herald

A high-tech SharkCam invented by a Cape Cod researcher offers an unprecedented window into the lives of the ocean’s toothy predators, and can also extend to seals, whales, turtles and squid for a big-picture view of precious ecosystems and how to protect them. “These vehicles, these underwater robots that look like highly complex systems are just an extension of yourself to be able go where people can’t go, and there’s no limitation to what they can do,” said Amy Kukulya, research engineer and principal investigator at Woods Hole Oceanographic Institution.

Melting ice imperils 98% of Emperor penguin colonies by 2100

The Associated Press

WASHINGTON (AP) — With climate change threatening the sea ice habitat of Emperor penguins, the U.S. Fish and Wildlife Service on Tuesday announced a proposal to list the species as threatened under the Endangered Species Act. “The lifecycle of Emperor penguins is tied to having stable sea ice, which they need to breed, to feed and to molt,” said Stephanie Jenouvrier, a penguin ecologist at the Woods Hole Oceanographic Institution.

What Happens to Marine Life When There Isn’t Enough Oxygen?

SciTech Daily

In September of 2017, Woods Hole Oceanographic Institution postdoctoral scholar Maggie Johnson was conducting an experiment with a colleague in Bocas del Toro off the Caribbean coast of Panama. After sitting on a quiet, warm open ocean, they snorkeled down to find a peculiar layer of murky, foul-smelling water about 10 feet below the surface, with brittle stars and sea urchins, which are usually in hiding, perching on the tops of coral. This unique observation prompted a collaborative study explained in a new paper published on July 26, 2021, in Nature Communications analyzing what this foggy water layer is caused by, and the impact it has on life at the bottom of the seafloor.

Impact of Hypoxic Ocean Waters on Marine Life

Investigators suggest that loss of oxygen in the global ocean is accelerating due to climate change and excess nutrients, but how sudden deoxygenation events affect tropical marine ecosystems is poorly understood.

Sharks and the ocean’s twilight zone: Some female great white sharks can deep dive for hours

Boston Herald

Much of the shark focus around the Cape is on great whites roaming close to the shoreline as they prowl for seals, but researchers are finding out that several sharks are actually diving deep into the twilight zone out in the middle of the ocean. Scientists at Woods Hole Oceanographic Institution on Cape Cod are researching the sharks’ deep diving behavior and how sharks’ bodies have evolved to handle these deeper conditions. They’re learning that deep diving is far more frequent and extensive across species than previously thought, said Simon Thorrold, a senior scientist in the biology department at the Woods Hole Oceanographic Institution.

New Ocean Buoy Monitors Whales Off MD.’s Atlantic Coast

The buoy is equipped with a hydrophone to record marine mammal calls, and thanks to an algorithm, researchers will be able to determine whether they belong to a humpback, fin, sei, or a critically-endangered North Atlantic Right whale.

Alvin: Pioneer of the Deep

WPBT

The deep-sea submersible Alvin has brought explorers to extraordinary places for more than 50 years. Now, as Alvin is poised to continue its revolutionary scientific work, a new set of upgrades will take it deeper than ever before. A coproduction with the Woods Hole Oceanographic Institution.
