A big lump of sand in the North Sea

22 March 2012

A ten cubic km wedge of sand now exists in the northern North Sea basin, somewhat south of Norway and east of Scotland, enough to bury Manhattan island under 160m of sand or the whole of London under 6m of sand (and that is an awful lot of the stuff). It appears to be extrusive – rising up from the gizzards of the earth. The paper is in the journal Geology March 19th but the big question might be – if sand is formed from eroded rocks why was so much of it buried under the sea floor?
