Computer modelling points to age specific ocean mortality as a reason chinook salmon returning to Alaska rivers are trending younger and smaller. As KUAC’s Dan Bross reports, a recently published study points to the loss of 3-year-old fish, and the possibility the larger chinook may be more targeted by salmon sharks and other marine predators.

A University of Alaska Fairbanks scientist has led development of a way to anticipate volcanic eruptions years in advance. The approach uses satellite imagery to track small changes in temperature on lands around the base of a volcano. KUAC’s Dan Bross reports.

UAF Mars Research

Landing of NASA’s Perseverance Rover has focused world attention on Mars. Meanwhile lesser known to the public, scientists at the University of Alaska Fairbanks are also studying the red planet. KUAC’s Mary Auld reports.

Omega 3 fats help arctic ground squirrels stay warm during hibernation. That’s the finding of research at the University of Alaska Fairbanks published last month in the journal Scientific Reports. As KUAC’s Mary Auld (ALD) reports, the study provides insight into how diet can affect body regulation.

A cruise brought researchers from universities around the country to the Bering and Chukchi seas last month to monitor ocean ecosystems. As KUAC’s Mary Auld reports, the annual trip went off later than normal due to the pandemic.
