Glaciologist Martin Truffer changed his team’s plan the other day. He and a crew of other scientists were about to travel to Malaspina Glacier — near the elbow of Alaska where Southeast Alaska hinges onto the mainland — but the glacier has wrecked his campsite. “Mark Fahenstock [another team member] looked at velocities of […]
Volcanic eruptions are not easy to anticipate. Now, a new paper proposes a way to provide early clues by evaluating magma movement far beneath volcanoes. The Bárdarbunga volcanic system in Iceland began to erupt from a fissure on Aug. 29, 2014. By the time it quit six months later, it had created an almost 33-square-mile lava […]
WASHINGTON — Phytoplankton blooms that form the base of the marine food web are expanding northward into ice-free waters where they have never been seen before, according to new research. A new study based on satellite imagery of ocean color reveals phytoplankton spring blooms in the Arctic Ocean, which were previously nonexistent, are expanding northward […]
PENTAGON — Chinese military vessels are now operating in the Northern Atlantic, and Russian submarines are prowling those same waters at a pace not seen since the end of the Cold War, the Navy’s top admiral told VOA in an exclusive interview. Chief of Naval Operations Adm. John Richardson said China’s military movements from the North […]
New research involving a University of Alaska Fairbanks scientist suggests that social behavior of salmon and other fish is an important puzzle piece that has been missing from fisheries conservation. Collective movement, which is the study of why and how animals move in groups, can explain many aspects of fish behavior. It may influence when […]
A major shift in western Arctic wind patterns occurred throughout the winter of 2017 and the resulting changes in sea ice movement are possible indicators of a changing climate, says Kent Moore, a professor of physics at the University of Toronto Mississauga. Thanks to data collected by buoys dropped from aircraft onto the Arctic Ocean’s […]
Right now, young Chinook salmon are leaving the rivers they were born in to begin life at sea. The first year in the ocean is thought to be the most critical time in the life of a salmon, and largely decides how many will live and be available to harvest as adults or return to […]
