United Kingdom - May 22nd, 2012

A bright blue phytoplankton bloom, separated into two close yet separate areas, can be observed in the North Sea off the coast of the United Kingdom. Also visible by the coast are sediments from several rivers. Southwest of the phytoplankton bloom are sediments from the rivers Witham, Welland, Nene and Great Ouse, in the Wash, the square-mouthed bay and estuary on the northwest margin of East Anglia on the east coast of England, where Norfolk meets Lincolnshire. It is among the largest estuaries in the United Kingdom. Further down the coast are sediments from the River Thames, east of London. On the opposite side of the island are sediments from the River Severn in the Severn Estuary and the Bristol Channel.

Sediments in the Bristol Channel, United Kingdom

The Bristol Channel is a major inlet in the island of Great Britain, separating South Wales from Devon and Somerset in South West England. Here, it appears brown in color due to sediments. It extends from the lower estuary of the River Severn to the North Atlantic Ocean. It takes its name from the English city of Bristol, and is over 30 miles (50 km) across at its widest point.

The upper limit of the Channel is between Sand Point, Somerset and Lavernock Point in South Wales. East of this line is the Severn Estuary. Western and northern Pembrokeshire, and north Cornwall are outside the defined limits of the Bristol Channel, and are considered part of the seaboard of the Atlantic Ocean, more specifically the Celtic Sea.

This FAPAR image shows the vegetation index of the United Kingdom (upper left) and stretches over France, Belgium, the Netherlands and Germany.

Photosynthetic activity is highest (rusty red) in western England and Wales, particularly near the Bristol Channel. The rest of the image shows a generally good (green) vegetation index.

UK and France - September 28th, 2011

Greenish gold sediments pour from the River Thames, in England, through its estuary, and into the North Sea. From there, currents carry them northeastward, parallel to the coasts of France, Belgium and the Netherlands.

On the opposite side of the United Kingdom, reddish brown sediments from the River Severn flow into the Bristol Channel. The channel separates southern Wales from southwestern England.


Sediments in Irish Sea and English Channel – April 3rd, 2011

United Kingdom, Ireland, France - March 23rd, 2011

Sediments color the waters of the Irish Sea (left, between Ireland and Great Britain), the English Channel (center right, between England and France) and the North Sea (upper right, beyond the Channel).

The sediments trailing out into the North Sea come from the River Thames, and are quite concentrated in the river’s estuary. On the opposite coast, to the west, darker tan sediments from the River Severn flow into the Bristol Channel.

Sediments near the coast of France come from rivers such as the Couesnon (left of the large peninsula) and the Seine (right of the peninsula).
