Arctic planktonic foraminifera pelagic carbonate production and sedimentation under changing environmental conditions ...
The Arctic Ocean is substantially affected by ongoing warming and sea ice loss. Climatic change further influences biological processes. Altogether, this can result in a modification of the marine carbon cycle, alike important for the climate and the ecosystem of the Arctic Ocean and beyond. In orde...

The Arctic Ocean is substantially affected by ongoing warming and sea ice loss. Climatic change further influences biological processes.
