The guests on this Hometown Alaska have all been working on a study of ecosystem changes in the Bering and Chukchi Seas. They are among a multidisciplinary team of academic, government and private sector scientists who recently published a paper documenting dramatic changes in the Pacific Arctic ecosystems due to warmer ocean conditions. You can find the abstract of their paper here.
It was published in Nature Climate Change, a monthly peer-reviewed science journal covering all aspects of climate change from both physical and social sciences. It is published by Nature Research, which also publishes the weekly Nature magazine.
These scientists will walk us through their findings and explain the potential impact on human society. Among their observations? Bowhead whales that typically migrate south of St. Lawrence Island were observed year round north of the Bering Strait. And juvenile Arctic cod, which generally dominate in the north Chukchi Sea, were substantially more abundant in 2017 than in 2012 and 2013. Sea ice that used to start forming each fall has been absent or sparse into January and February and spring ice retreat has been earlier than normal in recent years. Join us, and your questions are welcome throughout the hour.
