A new tool described in a study published Aug. 3 in the Journal of Geophysical Research Oceans will help researchers predict one of climate change’s biggest threats to crabs: ocean acidity. Pilcher and his team wanted to help the fishery by creating a tool that could forecast acidity in the Bering Sea. Then they added in ocean acidity data collected from the region, and tested their new tool by having it forecast the acidity of the Bering Sea over a roughly 40 year period. But because juvenile crabs are more vulnerable to ocean acidity than adults, Goen said Pilcher’s model could provide important data. Goen said she hopes for more research on the changing ocean chemistry in the Bering Sea, so fishermen can make informed decisions.
