New NASA research has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover. As temperatures in the Arctic have warmed at double the pace of the rest of the planet, the expanse of frozen seawater that […]
[dropcap]P[/dropcap]alo Alto, CA– New research, led by former Carnegie postdoctoral fellow Summer Praetorius, shows that changes in the heat flow of the northern Pacific Ocean may have a larger effect on the Arctic climate than previously thought. The findings are published in the August 7, 2018, issue of Nature Communications. The Arctic is experiencing larger […]
[dropcap]F[/dropcap]ifteen miles inland from the frozen coast of the Arctic Ocean, Teshekpuk Lake is one of the largest freshwater bodies in Alaska. On its northern shoreline are sandy bluffs that hold fossils of walrus, ringed seals and beluga. Thousands of years ago, this shore was an ocean beach. Digging into that beach in the middle […]
Materials from Arctic Shelves are Changing the Water’s Composition: Scientists say the input of shelf-derived materials to the central Arctic Ocean over the past decade appears to be increasing. They further note that this increase is altering the water’s composition and could threaten biological productivity and species assemblages. Their results provide one of the first […]
