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.
