United Kingdom - August 15th, 2011

Sediments and some phytoplankton can be seen in the North Sea near the English Channel in this image of the United Kingdom (left), the Netherlands (upper right), Belgium (center right) and France (below).

The majority of the sediments, gold and green in color, are spilling forth from the Thames Estuary, in the United Kingdom. On the opposite shores, sediments are also present in and near the Rhine-Meuse-Scheldt Delta, a river delta in the Netherlands and Belgium formed by the confluence of the Rhine, the Meuse and the Scheldt rivers.

The greenish streak in the North Sea in the upper part of the image is a trail of sediments known as the East Anglian Plume. The bright blue patch in the sea halfway between the UK and the Netherlands is most likely caused by phytoplankton.

    The greenish streak is known as the East Anglian Plume – possibly formed by the transport of fine sediments away from the Wash, Humber and Thames towards the Dutch coast. The plume has water of slightly lower salinity. Usually it is most visible in winter scenes, and diminishes in the summer as sediment loads decrease.
