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."
