Winds gusting to hurricane force raged over the sea for several hours
on October 27 and the Moderate Resolution Imaging Spectroradiometer on
NASA's Aqua satellite picked this out at 1:00 p.m. local time.

The sea had turned a foamy, white-flecked green off the shore of
Denmark. Westerly winds were driving waves into shore, creating a
fringe of white where waves crashed onto the beach. In the image,
glimmers of white glint in the murky waters offshore where waves break
over the shallow continental shelf.

The violent sea churned up clouds of sediment, giving the water the
brown and green color seen here. Clearer, deep water farther north is
nearly black, by contrast.

Nothing out of the ordinary for the North Sea. In that storm four
trawlermen died.
