An unprecedented coastwide toxic algal bloom linked to anomalous ocean conditions
A coastwide bloom of the toxigenic diatom Pseudo-nitzschia in spring 2015 resulted in the largest recorded outbreak of the neurotoxin, domoic acid, along the North American west coast. Elevated toxins were measured in numerous stranded marine mammals and resulted in geographically extensive and prolonged closures of razor clam, rock crab, and Dungeness crab fisheries. We demonstrate that this o...

In July 1998 Alaska’s Governor Tony Knowles submitted a request for federal disaster relief owing to severe economic and social hardships in some western Alaska communities affected by unusually poor salmon runs, especially Bristol Bay sockeye salmon Oncorhynchus nerka and Yukon River chinook O. tshawytscha and summer chum O. keta salmon. Other anomalies were also noted in these runs: late run ...
متن کاملMultispecies mass mortality of marine fauna linked to a toxic dinoflagellate bloom
Following heavy precipitation, we observed an intense algal bloom in the St. Lawrence Estuary (SLE) that coincided with an unusually high mortality of several species of marine fish, birds and mammals, including species designated at risk. The algal species was identified as Alexandrium tamarense and was determined to contain a potent mixture of paralytic shellfish toxins (PST). Significant lev...
متن کاملHarmful Algal Bloom Characterization Via the Telesupervised Adaptive Ocean Sensor Fleet
We are developing a Sensor Web-relevant system called the Telesupervised Adaptive Ocean Sensor Fleet that uses a group of National Oceanic and Atmospheric Administration extended-deployment autonomous surface vehicles to enable in-situ study of surface and sub-surface characteristics of Harmful Algal Blooms (HAB). The architecture supports adaptive reconfiguration based on environmental sensor ...
