The ‘blob’ of anomalously warm surface water that persisted in the North Pacific Ocean from 2013-2016 resulted in a massive harmful algal bloom (HAB) of Pseudo-nitzschia along the entire U.S. west coast. The bloom produced record-breaking concentrations of domoic acid, a marine neurotoxin, that contaminated seafood and necessitated fisheries harvest...
Future predictions of environmental conditions in Puget Sound exhibit an increased frequency and temporal extent of paralytic shellfish toxin closures. These predictions, generated using experimentally-derived growth responses of the common toxin-producing Alexandrium together with simulations of climate and local hydrology, depict a scenario in which the number of days favorable...
