NOAA has announced that a large marine heatwave and a developing El Niño are expected to impact West Coast marine species. These dual warming events could shift fisheries, harm salmon, and affect marine mammals.
- Market squid have moved north, creating new fishing opportunities in Oregon and Washington. - Tropical species like whale sharks and yellowfin tuna are appearing farther north than usual.
- California sea lion pups have faced starvation due to declines in their prey. - Harmful algae blooms have shut down crab fisheries, and salmon face lethal river temperatures.
The situation is less extreme than the 2015-2016 Blob and El Niño, but similar impacts are expected. Strong coastal upwelling may help moderate some warming effects.
