About Northeast HAB

The management of harmful algal blooms (HABs) in New England has grown more challenging due to the emergence of New HAB species that can cause seafood poisoning and disrupt ecosystems.  The Northeast HAB website was created as a regional resource that provides background information as well as access to bloom monitoring data and commentary, forecasting model products, and data collected by HAB sensors deployed throughout the region.

Alexandrium catenella nowcast/forecast for the Gulf of Maine

Annual Alexandrium catenella blooms in the Gulf of Maine produce potent neurotoxins that accumulate in shellfish and cause Paralytic Shellfish Poisoning (PSP) in human consumers. NOAA NCCOS has developed Gulf of Maine Alexandrium catenella predictive models to better predict and monitor blooms of this species and and shellfish toxicity with the goal to minimize impacts to public health and coastal economies. Information for 2022 is posted HERE, and will be updated with 2023 information when available.
