[font size=3]CORVALLIS, Ore. Researchers today reported in Proceedings of the National Academy of Sciences a strong correlation between toxic levels of domoic acid in shellfish and the warm-water ocean conditions orchestrated by two powerful forces El Niño events and the Pacific Decadal Oscillation.
Using a combination of time-series data spanning two decades, the scientists not only showed a clear link between domoic acid and these larger climatic phenomena, but also developed a new model to predict with some accuracy the timing of
domoic acid risks in the Pacific Northwest.
The model is based on interpreting the status of the Oceanic Niño Index and the Pacific Decadal Oscillation both of which are measures of climate, ocean water movement, currents and temperature. Its designed to help coastal resource managers more effectively monitor this issue and protect public health.
Domoic acid, a potent neurotoxin produced by specific types of phytoplankton and ingested by shellfish, can cause serious health effects in humans and some other animals. In recent years, dangerous levels of these toxins have led to the repeated closure of crab and shellfish harvesting in the Pacific Northwest and elsewhere. The problem threatens public health, marine wildlife and can cost millions for coastal economies. Until now, its connection to larger climatic forces has been suspected, but not confirmed.
