Human footprints preserved in mud at White Sands National Park in New Mexico suggest that humans arrived there — possibly via Alaska — at least 21,000 years ago. No one alive today knows how people got that deep into North America from Asia so long ago. But a team of scientists has proposed winter sea […]
A massive new analysis of high seas salmon surveys is enhancing the understanding of salmon ecology, adding details about where various species congregate in the North Pacific Ocean and their different temperature tolerances. The project, led by researchers at the University of Alaska Fairbanks, integrates numerous international salmon studies from the North Pacific dating back to the […]
Ocean temperatures in the Bering Strait and heat transport through the region have increased over the past 20 years. New modeling using a range of temperatures shows that reduced regional September sea ice occurs one to three months after a heat increase. That’s the preliminary finding of research by University of Alaska Fairbanks doctoral student […]
SAN FRANCISCO — In December 2006, I sat in a similar carpeted room in this city and listened to scientists talk about an Alaska-size chunk of sea ice that was no longer floating on the northern oceans compared to previous years. That meant that the “refrigerator of the northern hemisphere” was much less powerful than […]
