Envisat captures a crescent-shaped string of plankton in the North Sea weaving through the Scandinavian region. Norway (left) and Sweden (right), part of the Scandinavian Peninsula, are visible at the top, and Denmark is at bottom right. The emerald green lake seen in Sweden is Vänern, the country’s largest. The green water around Denmark is due to sediments being transported in the water. Also visible (image centre) is Norway’s second largest fjord, Hardangerfjord.
