Northeast - Red Tide/Shellfish Closure Extension Through December 31, 2011 At the request of the U.S. Food and Drug Administration, NOAA Fisheries Service has extended the temporary paralytic shellfish poisoning (PSP) closure through December 31, 2011, due to the presence of high levels of the toxin that causes PSP. See a chart of the closure area. NOAA Fisheries Service may terminate the emergency regulations at an earlier date by publishing a notice of termination in the Federal Register if information becomes available indicating such action is warranted.

"To help cool a warming world, some scientists have suggested fertilizing the oceans with iron. The idea is to stimulate vast blooms of phytoplankton, which sequester carbon dioxide. But such an approach could have deadly consequences. Experiments in the northern Pacific Ocean show that phytoplankton in waters far from land produce a molecule called domoic acid, a neurotoxin that has killed wildlife and people in coastal areas. "
