Abstract

Little is known about the sensitivity of Antarctic krill, a key part of the food chain, to ocean acidification. A circumpolar risk map of krill hatching success is presented for projected ocean acidification levels. Important krill recruitment habitats are likely to become high-risk this century, with the possibility of collapse of the krill population by 2300 without mitigation of CO2 emissions.
