A new study led by Colorado State University has found that glacial lakes in Alaska are expanding at an accelerating rate as glaciers melt, with rapid expansion over just six years. The research also projects where lakes could grow or form in the future – critical information for planning and public safety. The […]
Alaska’s glaciers respond to climate change by melting for three additional weeks with every 1 degree Celsius increase in the average summer temperature, data from satellite-mounted radars show. A single degree Celsius equates to 1.8 degrees Fahrenheit. Work by scientists at Carnegie Mellon University and the University of Alaska Fairbanks also shows that synthetic […]
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 […]
