- Although technically not “cryosphere” (which is frozen water), the Arctic Ocean, and Southern Ocean around Antarctica make up some of the world’s richest fisheries, with diverse marine ecosystems. These cold waters are however highly vulnerable to ocean acidification from increased carbon dioxide (CO2) in the atmosphere.
