Forecasting Pseudo-nitzschia blooms

Project background

The neurotoxin domoic acid (DA), produced in Pacific Northwest (PNW) coastal waters by blooms of the diatom Pseudo-nitzschia (PN), bioaccumulates in razor clams and other shellfish, causing amnesiac shellfish poisoning if consumed. Razor clams support tens of millions of dollars annually in coastal tourism, and are essential to the Quinault Indian Nation and other Washington tribes for subsistence and commercial income. This proposal supports the development of a monitoring- and modeling-based forecast system for PN and particulate DA (pDA) on beaches from Cape Flattery, WA, to Heceta Head, OR, in partnership with existing Washington and Oregon monitoring programs,

This project, titled “MERHAB: An early warning system for Pseudo-nitzschia HABs on Pacific Northwest outer-coast beaches” is part of NOAA’s Ecological Forecasting Effort and includes a plan to transition the Pacific Northwest HAB Forecasting Bulletin from research to operations.
