Less Phytoplankton Growth in Bay of Arguin, Mauritania

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.

Mauritania – August 26th, 2012

A plume of dust blows from the Sahara Desert blows off the coast of Western Sahara. The plume remains north of the Ras Nouadhibou (Cap Blanc) peninsula, shared by Western Sahara and Mauritania, and does not cover the green, phytoplankton-stained waters of the Bay of Arguin (below).

Mauritania - March 14th, 2012

The bright green and turquoise waters of the Bay of Arguin, in Mauritania, are so colored by the growth of phytoplankton. These microscopic organisms are invisible to the naked eye, but tinge water with dazzling colors when they reproduce in great numbers.

The waters are greenest along the shores by the peninsula of Ras Nouadhibou (Cap Blanc). A tan coloring can be observed in the lower part of the bay, apparently from dust blowing off the mainland and the island of Tidra, the largest island in the bay.

Mauritania - November 20th, 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 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.
