The algae is moving west Scientists are tracking the progress of a giant mass of algae which is causing the sea to change colour off the south-west coast of England. BBC Environment Correspondent Margaret Gilmore reports The bloom is the size of Cornwall and is visible from space as a white-coloured mass stretching from south Devon to the Scilly Isles and moving west. It has been caused by a rapidly expanding microscopic plant, Emiliania huxleyi.

Local fishermen say they have never seen anything like it.
