With such high ocean surface speed (someone mentioned ice drift speed of up to 1 m/s), and ice free conditions above some of the normally covered Arctic basement edges, I was wondering if the Arctic might be in for a fairly unique upwelling event, at least on the Siberian side, where the movement will be more or less parallel to the edge, with the deep water on the right-hand side.
Rather than speculating too much whether it will happen, one can just look for evidence.
Surface salinity would of course be a good signature to such an event, and I see there is this Aquarius satellite mission that can apparently measure it, but couldn't find any data - does anyone know where to find current satellite salinity data?
