June 23, 2015

Rising levels of acidity in oceans is a direct result of increased carbon dioxide concentrations in the atmosphere and over the course of next few decades acidity levels in Chukchi and Beaufort seas could reach levels of acidity that threaten the ability of animals to build their shells.

Arctic Acidification Poses Risks to Crustaceans and Fish

June 19, 2015

A new study has concluded that by 2030 Chukchi and Beaufort seas, in the Arctic Ocean, could reach acidity levels that may negatively affect not only shelled animals but also the fish depending on them.

Arctic Ocean Rapidly Becoming More Corrosive to Marine Species

June 18, 2015

New research by NOAA, University of Alaska, and Woods Hole Oceanographic Institution in the journal Oceanography shows that surface waters of the Chukchi and Beaufort seas could reach levels of acidity that threaten the ability of animals to build and maintain their shells by 2030, with the Bering Sea reaching this level of acidity by 2044.
