Climate History
An international team of scientists led by the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) have managed to open a new window into the climate history

in the Arctic differ fundamentally from those in non-polar oceans. A recent study, led by the Alfred Wegener Institute, in the journal Communications Earth & Environment , summarizes how these events have
