Geologists and geophysicists of the Alfred Wegener Institute, Helmholtz
Centre for Polar and Marine Research (AWI), discovered traces of large
ice sheets from the Pleistocene on a seamount off the north-eastern
coast of Russia. These marks confirm for the first time that within the
past 800,000 years in the course of ice ages, ice sheets more than a
kilometre thick also formed in the Arctic Ocean.
The climate history for this part of the Arctic now needs to be
rewritten, report the AWI scientists jointly with their South Korean
colleagues in the title story of the current issue of the scientific
journal Nature Geoscience. [...] sciencedaily.com
