Arctic Ocean freshwater bulge detected

Scientists have detected a huge bulge of fresh water 8000 cubic km in size in the western Arctic Ocean.
The bulge is thought to be the result of strong winds whipping up a clockwise current in the region. "In the western Arctic, the Beaufort Gyre is driven by a permanent anti-cyclonic wind circulation," said Dr Katharine Giles. "It drives the water, forcing it to pile up in the centre of gyre, and this domes the sea surface."
The data (1995-2010) indicates a significant swelling of water in the Beaufort Gyre, particularly since the early part of the 2000s. The rising trend has been running at 2cm per year.

Interesting stuff ... I don't think it would go well for Europe if there was a major shift in this balance.

It honestly wouldn't go well for anywhere for a salinity level change in one of the major oceans.
