Senegal and Guinea Bissau - June 2nd, 2009

Sediments flow into the Atlantic Ocean from rivermouths along the coast of West Africa. The rivers discharging the most sediments are the Cacheu and the Geba Rivers in Guinea-Bissau (bottom).

The waters of the Geba appear golden brown, in turn giving those around the Bissagos Islands a golden green tinge.

Moving northwards, the Casamance River becomes visible near the border between Senegal and Guinea-Bissau. Continuing north into the Gambia, surrounded by Senegal on three sides, the Gambia River can also be seen.

The sediments being discharged by these two rivers are greenish in color, as opposed to the golden ones of the Geba.

Finally, moving north of Dakar on the Cape Verde Peninsula, the Senegal River can be found on the border between Mauritania (above) and Senegal.

This full resolution image give us a fine view of the West African coast, from Dakar, Senegal (top left) to Cacine, Guinea-Bissau (bottom right), passing through The Gambia in the center. Moving southward, the terrain changes from arid desert to forest.

It also allows us to see many rivers flowing out into the Atlantic Ocean. The river located at the point where the terrain changes from tan to green is the Gambia River, 1,130 km (700 mi) long, reaching the Atlantic Ocean near the city of Banjul.

Further south, in Senegal, is the Casamance River, 320km (200mi) in length. Moving down into Guinea-Bissau, we have the Cacheu River (Farim River), 257 km long.

Continuing south through Guinea Bissau, the most visible river is the Geba, appearing tan due to sediments. As it flows past the capital city of Bissau and through the Bissagos Archipelago, we can see the sediments filter out into the Atlantic Ocean.

The Bissagos Archipelago, also known as the Bissagos Islands or the Arquipélago dos Bijagós, is a group of 18 major islands and dozens of smaller ones that constitute a UNESCO biosphere reserve.

South of the Geba River is the Corubal River, one of the Geba’s tributaries.
