Scientists find that some Pacific cod may be more vulnerable to climate change than others. Much of the success in managing U.S. fish species has come with recognizing local differences and genetic variability within species. Pacific cod are an important commercial fish species caught throughout Alaskan waters. Cod caught in the Gulf of Alaska and […]
New information may help with recovery efforts for endangered Cook Inlet belugas. When listening to beluga whales, the sound of a crunch or a clapped jaw may be a reliable indication that a beluga whale just successfully captured or missed a fish. In a new published paper on beluga whales in Alaska, scientists analyzed sound data, collected […]
Changes will happen decades earlier than previously thought More rain than snow will fall in the Arctic and this transition will occur decades earlier than previously predicted, a new study led by the University of Manitoba (UM) and co-authored by scientists at the National Snow and Ice Data Center (NSIDC) reports. Projections from the latest […]
“It is possible that the Arctic Ocean is more sensitive to greenhouse gases than previously thought,” said one of the study’s authors. New research published Wednesday revealed the Arctic Ocean has been warming for decades longer than scientists previously understood, raising fresh concerns as the polar region faces the growing threat of a total loss of […]
A University of Alaska Fairbanks scientist has discovered a method for detecting and better defining meteorite impact sites that have long lost their tell-tale craters. The discovery could further the study of not only Earth’s geology but also that of other bodies in our solar system. The key, according to work by associate research professor Gunther […]
Genes evolved under intense poaching pressure In regions of Africa wracked by heavy poaching, scientists have observed an increasing number of African elephants without their iconic white tusks, prized in the multibillion-dollar wildlife black market. But there has been no direct evidence indicating how this was happening or why this trait was occurring exclusively in […]
New research shines light on poorly understood processes Geoscientist Michael Rawlins of the University of Massachusetts Amherst is improving the understanding of the Arctic’s carbon cycle — the way carbon is transferred among the land, ocean and atmosphere. To better understand future trends in atmospheric carbon dioxide and climate change, a fuller picture of how carbon cycles […]
Melinda Webster splashed daily through the clear water of Arctic melt ponds to measure the depth of the water cradled in pockets dotting the polar sea ice. She was a common sight in the white and blue icescape in which the research vessel Polarstern, her home for 126 days last year, had been deliberately left to […]
JUNEAU — The University of Alaska Southeast (UAS) will recognize Indigenous Peoples’ Day with a conversation event titled “Ḵaa Tukax̱saké Héende – Towards the River That Untangles a Personʼs Mind.” The events begin at 9 AM on Monday, October 11, with a panel discussion in the afternoon on the Future of Indigneous Language Revitalization from […]
