Arctic Ocean chemistry changes dramatically during winters

Arctic winter is not quiet. New research shows that dissolved carbon becomes easier for microbes to use, reshaping the ocean’s carbon cycle.

"It shows that the carbon cycle is active even in winter. (...) It is important because the ocean is getting warmer, and thus the entire balance can change. Warmer seas mean that seasonal variations can also be different" #Arctic

When it comes to storing carbon, the Arctic presents a winter surprise

The ocean holds gigantic amounts of carbon, much more than all land-based plants and soil. Scientists previously studied these carbon stocks in spring and summer. Now, in two published studies, they h...
