In the fall of 2014 a persistent weather pattern in the northeastern Pacific stopped the normal upwelling of cold water from Alaska to California. Sea surface temperatures rose 7 degrees F.
When that happened, cold water nutrients and organisms stayed too far below the surface to feed the fish, birds and animals that depend on them. Species starved throughout the food chain including crabs, sea stars, salmon, Cassin’s auklets, common murres, and sea lion pups.
This month a similar weather pattern has created a similar temperature anomaly. NOAA says it already ranks as the second largest marine heatwave in the northern Pacific Ocean in 40 years — second only to “the Blob.” (see maps above)
If the weather doesn’t change soon, if the winds don’t pick up and stir the sea, then “The Blob” will be back again and it will be bad news for everything in the northeastern Pacific.
