Observations and Analyses of HAB blooms in Warming Alaska Waters

The waters of western and northern Alaska, including the Bering, Chukchi, and Beaufort seas, are changing due to climate-driven warming, leading to an elevated risk of Alexandrium catenella blooms and paralytic shellfish toxins (PSTs). PSTs are a recognized health concern in southeastern Alaska, but the distribution, dynamics and impacts of A. catenella blooms in the northern waters of the region are largely unknown. This talk synthesizes six years of observations and analyses (2018-2023). For a link to the presentation by Don Anderson given on 2/28/24 at the University of Washington, click here.
