SPACE, SPACE: This NASA satellite image released 05 August, 2004 shows an enormous bloom of phytoplankton floating in the cool waters of the Barents Sea off the northern coast of Norway. Phytoplankton are microscopic plants that turn ocean waters bright blue and green, and are common in Earth imagery taken from space. The bright blue color suggests that this bloom may be caused by coccolithophores, which are tiny plants surrounded by white calcium carbonate (chalk) plates. The white plates reflect light, and turn the blue waters to shades of blue, green, and turquoise. AFP PHOTO/HO/NASA (Photo credit should read )
