- Tracking a large-scale and highly toxic Arctic algal bloom: rapid detection and risk communication. Fachon, Evangeline Pickart, Robert S Sheffield, Gay Pate, Emma Pathare, Mrunmayee Brosnahan, Michael L Muhlbach, Eric Horn, Kali Spada, Nathaniel N Rajagopalan, Anushka Lin, Peigen McRaven, Leah T Lago, Loreley S Huang, Jie Bahr, Frank Stockwell, Dean A Hubbard, Katherine A Farrugia, Thomas J Lefebvre, Kathi A Anderson, Donald M In recent years, blooms of the neurotoxic dinoflagellate have been documented in Pacific Arctic waters, and the paralytic shellfish toxins (PSTs) that this species produces have been detected throughout the food web. These observations have raised significant concerns about the role that harmful algal blooms (HABs) will play in a rapidly changing Arctic. During a research cruise in summer 2022, a massive bloom of was detected in real time as it was advected through the Bering Strait region. The bloom was exceptional in both spatial scale and density, extending >600 km latitudinally, reaching concentrations >174,000 cells L, and producing high-potency PST congeners. Throughout the event, coastal stakeholders in the region were engaged and a multi-faceted community response was mobilized. This unprecedented bloom highlighted the urgent need for response capabilities to ensure safe utilization of critical marine resources in a region that has little experience with HABs.
