Mauritania – October 22nd, 2012

The usually neon green phytoplankton growing in the waters of the Bay of Arguin, off the coast of Mauritania, are a bit dimmer in this fall image. The bay is located south of Cap Blanc, north of Cap Timiris, and contains the islands of Arguin and Tidra, as well as the 12,000 km² Banc d’Arguin National Park.

The Bay of Arguin, or Banc d’Arguin, is a bay on the Atlantic shore of Mauritania. It is south of Cap Blanc, north of Cap Timiris, and contains the islands of Arguin and Tidra. The bay contains the Banc d’Arguin National Park.

The Bay of Arguin is an area of over 10,000 km2 of shallow water and tidal flats between the Sahara and the upwelling system off the Mauritanian coast. Hydrographically, the bay can be characterized as a large-scale negative estuary with higher salinities near the shore, whose ecosystem is fueled by nutrients and organic matter derived from the upwelling area. Phytoplankton feeding on these nutrients and organic matter give the bay its bright green color.

Mauritania - November 4th, 2011

The Bay of Arguin, or Banc d’Arguin, is a bay on the Atlantic shore of Mauritania. It is south of Cap Blanc, north of Cap Timiris, and contains the islands of Arguin and Tidra. The bay contains the 12,000 km² Banc d’Arguin National Park.

The Banc d’Arguin National Park lies in Western Africa on the west coast of Mauritania between Nouakchott and Nouadhibou. The World Heritage Site is a major breeding site for migratory birds. The surrounding waters, here appearing green from algal growth, are some of the richest fishing waters in western Africa and serve as nesting grounds for the entire western region.

Sediments and algal growth give a bright green color to the waters of the Bay of Arguin (or Banc d’Arguin), on the Atlantic shore of Mauritania.

The bay is south of Cap Blanc, north of Cap Timiris, and contains the islands of Arguin (above) and Tidra (below). Both are best observed in the full image. Tidra is the largest island in the bay, at 18 miles long and 5 miles wide.

Mauritania - January 16th, 2011

The green waters of the Bay of Arguin (or Banc d’Arguin), a bay on the Atlantic shore of Mauritania, are caused by intense phytoplankton reproduction. The bay contains the 12,000 km² Banc d’Arguin National Park and the islands of Arguin and Tidra.

Tidra is an offshore island 18 miles long and 5 miles wide. It is easily spotted in this image as it is the largest island off the shore of the bay. Arguin, visible in the full image due north of Tidra, is six km long by two km wide. Extensive and dangerous reefs are located in the waters by the island.
