A changing climate resulting in reduced sea ice coverage is causing Indigenous seal hunters who rely on the marine mammals for subsistence to change their methods. As the ice continues to change, their ability to …
In the eastern Canadian Arctic and Greenland, Inuit have told stories for centuries of polar bears using rocks and blocks of ice to bludgeon walruses to death. Naturalists discounted such tales as myths, but new …

The U.S. Department of the Interior will not pursue the previous administration’s plan to ease restrictions on exploratory drilling in the Arctic. In 2020, during the previous administration, the Bureau of Safety and Environmental Enforcement …
Narwhal tusks can tell researchers a lot about the marine mammals’ feeding habits and exposure to dangerous chemicals. “They’re kind of like tree rings,” said Jean-Pierre Desforges, a postdoctoral research fellow at McGill University. “As …
The loud sounds bearded seals emit underwater may not be noisy enough to overcome the sound from increasing industrial activities off the coast of Alaska. Recent research highlighted how bearded seal (Erignathus barbatus) noise can …
Climate change is causing energy use problems for Arctic mammals. Melting or shifting ice patterns means both narwhals (Monodon Monoceros) and polar bears (Ursus maritimus) need to travel more to find food. Polar bears normally …
Heat may stress out snowbirds, despite the fact that they live in areas most people would consider cool at best. As climates continue to warm, this type of stress may be on the rise, possibly …
Bearded seals create a deafening underwater soundscape in the Canadian Arctic Ocean — particularly during mating season. Explorations of the types of sounds they make and the volume of those noises can help researchers eventually …
Murre colonies that experienced die-offs in the Bering and Chukschi seas off the coast of Alaska in 2018 also experienced reproductive failure. “The majority of colonies that we surveyed in 2018 had suffered complete — …
