The inbis channel: The most complete submarine cartography  

A scientific study describes for the first time the submarine cartography of a high-latitude system in the IBIS channel, which covers tens of kilometers in the northern western area of the Barents Sea, in the Arctic Ocean. This channel is one of the few submarine valleys in polar latitudes that kept its geological architecture during the Last Glacial Maximum (LGM).
