Dinosaur tracks in Alaska provide evidence of a previously unknown high latitude dinosaur region. The discovery includes four-toed tracks suggestive of armored or horned dinosaurs and pebbly texture skin impressions, revealing the diversity of ancient species that flourished in the Arctic.
Salmon returns have fallen short of expectations in Alaska, with declines attributed to natural ocean cycles and potential regime shifts. Scientists attribute the changes to shifts in phytoplankton species composition and plankton abundance.
A joint research project is underway to locate and evaluate the condition of sunken whaling vessels lost off Alaska's north coast in 1871. The expedition, led by the West Coast and Polar Regions Undersea Research Center, utilizes side-scan sonar and a remotely operated vehicle (ROV) provided by NASA.
Scientists model 1883 tsunami impact on English Bay and Homer Spit, predicting energy absorption at Anchor Point and flooding risk at Homer Spit. The model helps emergency planners understand risks and plan for potential landslides and tidal waves.
