Inuit–researcher collaboration provides the first direct evidence that Arctic marine predators feed intensively at tidewater glacier fronts Studying foraging behavior in marine mammals is especially difficult. Unlike terrestrial animals, which can often be directly observed, marine mammals feed underwater and across vast, remote areas, making it challenging to determine where and what they eat. […]
A powerhouse of ice flows rapidly on Greenland’s west coast, heading toward the ocean. Some of Earth’s largest icebergs are produced here, tumbling from the tip of Jakobshavn Glacier. Jakobshavn is one of Earth’s fastest-moving glaciers and one of the Greenland Ice Sheet’s largest glaciers. It produces about 10% of Greenland’s icebergs. “We don’t have a good […]
Scientists have produced the first remote sensing analysis of how water clouded by sediment in glacier meltwater moves on the surface of Kachemak Bay. The bay on Alaska’s Kenai Peninsula is home to a rich variety of marine life that can be affected by the sediment. Work led by Lea Hartl of the Alaska Climate Research […]
Glaciers worldwide are withering. Half of them will disappear by the end of this century, and much of the lost ice will vanish from mountains in Alaska, scientists say. Authors of a recent cover story in the journal Science used high-performance computers to predict the fate of 215,547 glaciers on Earth. They excluded the great […]
