September 9, 2019 — A marine heat wave off the West Coast is causing ocean temperatures to rise from Alaska to California. Scientists say it looks a lot like the warm water mass they nicknamed the blob five years ago.
DAVID GREENE, HOST:
All right. Ocean temperatures, from Alaska down here to California, have been rising. This is a marine heat wave, and scientists say it looks a lot like a mass of warm water that appeared five years ago and was nicknamed “the blob.” Cassandra Profita with Oregon Public Broadcasting has more.
CASSANDRA PROFITA, BYLINE: The current marine heat wave isn’t quite as big or as warm as the blob, at least, not yet. But the last heat wave caused major upheaval in the ocean. A toxic algae bloom made it unsafe for people to eat shellfish up and down the coast so many crab and clam fisheries were closed. Salmon and sea lions had less food to eat, and warm-water species started showing up farther north. Chris Harvey is a biologist with the National Marine Fisheries Service.
CHRIS HARVEY: Given the severity of the last marine heat wave, the blob, we definitely felt it was our responsibility at this point to say this is something that we are concerned about, and we’re going to continue watching it with regular monitoring along the West Coast.
