Marine capture fisheries in the Arctic: winners or losers under climate change and ocean acidification?
Abstract Climate change, ocean acidification (OA) and the subsequent changes in marine productivity may affect fisheries and eventually the whole economy in the Arctic. We analysed how changes in climate and ocean pH under scenarios of anthropogenic CO 2 emissions are likely to affect the economics...
