Today NPR’s All Things Considered ran this piece that focused on Seattle-based scientists who are working in Puget Sound to try to predict the appearance of red tides.
Neither communist plot nor NCAA Division I athletic program, a red tide is an algal bloom that releases neurotoxins dangerous to sea life that ingest the algae as well as animals (human and otherwise) higher up the food chain. Shellfish in particular can pass on these neurotoxins to human diners with decidedly unpleasant consequences. As such, state officials close fisheries when affected by these blooms, with the predictable economic ripple effects for those who harvest, prepare, and serve shellfish.
For a bit more of the biology and chemistry of the organisms that make up red tides, check out this piece from Jennifer Frazer’s “The Artful Amoeba” blog at Scientific American.
