The latest findings on the MOSAiC floe

The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018. Sediments, and even small pebbles and bivalves, were incorporated into the ice during the freezing process, which the ongoing melting process has brought to light on the surface of the MOSAiC floe. This is an increasingly rare phenomenon as today, most “dirty ice” melts before it even arrives in the Central Arctic. These are among the main findings of a study that MOSAiC experts have published now in the journal The Cryosphere, and which will provide the basis for numerous upcoming scientific assessments.
