Ancient Arctic carbon is pouring into the sea, but the seabed captures most of it
✦AI Summary
Researchers studying the Arctic coast have found that while thawing permafrost releases organic carbon into the ocean, the seafloor acts as a significant long-term storage site. Marine microorganisms appear to prioritize fresh carbon over older permafrost-derived carbon, influencing how much greenhouse gas is released into the atmosphere.
The Arctic's frozen ground contains enormous stores of organic carbon. As permafrost thaws and coastlines erode, some of that carbon is carried into the ocean. There, microorganisms can break it down and release greenhouse gases that contribute to climate change.
