English: Rippling clouds of phytoplankton bloom off the south western side of Norway in the North Sea in this true-colour Terra MODIS image acquired on June 5, 2003. The bloom stretches out in three directions at once—off to the north west, down to the south west, and in a thinner stream to the south east—making it look a little like a pin-wheel. To the west of the pin-wheel is northern Scotland and England, while to the south-east is north-western Denmark.
