Since 2018, more than 10 billion snow crab have disappeared from the eastern Bering Sea, and the population collapsed to historical lows in 2021. We link this collapse to a marine heatwave in the eastern Bering Sea during 2018 and 2019. Calculated caloric requirements, reduced spatial distribution, and observed body conditions suggest that starvation played a role in the collapse. https://www.science.org/doi/10.1126/science.adf6035 #SnowCrab#MarineHeatwave#Heatwave
"South-east #Australia#marine#heatwave forecast to be literally off the scale - Patch of Tasman sea expected to warm over spring and summer to temperatures that risk significant losses to sea life
Australia’s south-east could be in for a marine heatwave that is literally off the scale, raising the prospect of significant losses in fishing and aquaculture.
The Bureau of Meteorology has forecast a patch of the Tasman Sea off Tasmania and Victoria could be at least 2.5C above average from September to February, and it could get hotter.
Oceanographer Grant Smith said the colour-coded scale the bureau uses to map forecast sea surface temperature anomalies stops at 2.5C. “We didn’t account for anomalies that high when we developed this ... it could be 3C, it could be 3.5C, but we can’t see how high it goes,” he said.
...
South-eastern Australia is a known climate change hotspot with its waters warming about four times faster than the global average."
A massive #MarineHeatWave has settled off the coast of the Pacific Northwest #PNW with SSTs 8F above normal. It is expected to persist at least through the end of summer.
Half of the world’s ocean may experience #marineheatwave conditions by September, NOAA’s forecast predicts. Such unprecedentedly widespread extreme ocean temperatures can disrupt ocean ecosystems and could mean stronger hurricanes.
