Senegal River Between Mauritania and Senegal16.6N 15.7W
The dry, tan of the Sahara Desert in Mauritania turns greener and more vegetated at the bottom of this image, in Senegal. Visible roughly at the center of the coastline is the Senegal River, which marks the border between Mauritania and Senegal.
In the upper left quadrant, one can observe the Bay of Arguin, green with algal growth, while in the middle is visible the bulls-eye shaped Richat Structure. In the lower left quadrant, the greenish color offshore is due to sediments from the Geba River in Guinea-Bissau.
