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.

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.

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.

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 (above center) and Tidra (below). The bay also contains the 12,000 km² Banc d’Arguin National Park. Here, its waters appear greenish due to nutrient-rich offshore waters teeming with phytoplankton.

The bay is an area of shallow water and tidal flats between the Sahara and the upwelling system off the Mauritanian coast. Hydrographically the Banc d’Arguin can be characterized as a large-scale negative estuary with higher salinities near the shore. It is concluded that ultimately the Banc d’Arguin ecosystem is fueled by nutrients and organic matter derived from the upwelling area.

The inner part of the Banc d’Arguin system is dominated by a detritus-based benthic foodweb in which seagrasses are the principal primary producers. Little of the seagrass production seems to be exported to other parts of the system or other areas. Zooplankton and zoobenthos biomasses are relatively low, but nevertheless support high densities of consumers. Aquatic birds are especially numerous.
