Changing ocean affects fish food quality

An experiment in the Baltic Sea demonstrated for the first time that ocean acidification and rising water temperatures harms the fatty acid composition of copepods in the natural plankton community. As a consequence, fish might find food of poorer quality. Published in ECO. Continue reading

Siberian erosion, river runoff speed up Arctic Ocean acidification

As Siberian permafrost thaws, crumbling Russian coastlines and big rivers flowing north along eroding banks are dumping vast loads of organic carbon into marine waters there, causing much quicker acidification than had been anticipated.
