Grist: "Ocean is shattering heat records...here's what that means for fisheries." The Blob that started in late 2013 was a marine heat wave that started with unusually tepid water in the Gulf of Alaska, which grew to an area equivalent to the 48 states. "Over the course of two years, 1 million seabirds died, kelp forests withered, and sea lion pups got stranded." But in popular perception it carried little meaning, because there was no melting asphalt, rolling grid outages, no sweat-soaked shirts. 'Yet marine heat waves can “inject a lot of chaos,” said Chris Free, a fisheries scientist at the University of California, Santa Barbara.' More than gulls + sea snails suffer. Some 100 million Pacific cod [think fish + chips here] disappeared from the Gulf of Alaska. "In British Columbia and the Pacific Northwest, salmon runs – and the fishing industry that depends on them – floundered." In British Columbia and the Pacific Northwest, salmon runs – and the fishing industry that depends on them – floundered. "The Blob was the largest and longest-lasting marine heat wave on record." But other stories constitute evidence of the changing ocean: Fish farms in Chile, scallop operations in Australia, and snow crab pots in Alaska have already fallen victim to oceanic overheating. Six of the last seven Dungeness crab seasons in California have been delayed. So, is it time to ask yourself + your community what you should be changing to fight the dragon of weirding climate? I think the question answers itself.   #marineheatwaves    #climatechange

"‘Headed off the charts’: world’s ocean surface temperature hits record high

The temperature of the world’s ocean surface has hit an all-time high since satellite records began, leading to marine heatwaves around the globe, according to US government data."

New publication! Krieger et al. explore the physiological impacts of #marineheatwaves on coralline algal physiology in combination with simulated ocean warming scenarios.

when headlines talk about "scorcher" like it's gonna be a fun day at the beach. 😐 its very not-good. This for 3jan23 - ocean surface temperature anomaly (ie difference from normal) red=hot... from Ben Noll at #NIWA using #NOAA product. #MarineHeatWaves #Climate #OceanHeatContent
