Ocean Warming has Seafloor Species Headed in the Wrong Direction

September 7, 2020 By Erik Stokstad Science Magazine
As the world warms, many species of plant and animal will have to find new—often cooler—places to live. But things are trickier for sedentary marine creatures like snails, worms, and clams, according to a new study. It finds that in the Northwest Atlantic Ocean, many species are spawning earlier in the year, when currents take their larvae southward and into warmer waters—the wrong direction. For some of them, including the sand dollars beloved by beachcombers, this means their range is shrinking.

‘Microplastic Hot Spots’ Are Tainting Deep-Sea Ecosystems

By this point, it comes as no surprise to scientists that they would find the tiny bits of plastic in seafloor sediments—last year researchers found them in samples off the coast of Southern California. But in the Mediterranean, the sheer concentration of them is astounding.
