Scientists Found Causes of Arctic Ocean Acidification

21.04.2016

The results of the research conducted by Russian scientists, together with colleagues from Sweden and the USA, showed that acidification of the shelf waters in the Arctic ocean is happening not due to absorption of carbon dioxide from the atmosphere, but due to the melting of permafrost and the impact of desalinization of water from Siberian rivers.

Scientists Found Causes of Arctic Ocean Acidification

Due to warming the ancient organic matter released from permafrost into the ocean in the form of carbon dioxide, which forms a weak acid when dissolved, and the increase in the flow of rivers aggravates the process. Meanwhile, in the Arctic Ocean, the coldest one in the world, carbon dioxide dissolves better than in the other ones. Acidification is a threat to the entire ecosystem, and the most vulnerable of all are marine organisms whose shells and skeletons contain calcium. In addition, it disturbs balance in the food chains.
