North Eastern Atlantic

West of the Banc d’Arguin, the Atlantic deepens beyond a broad continental shelf of sandbanks and shallow channels. The bank lies between Cape Blanc and Cape Timiris, where desert dunes meet the ocean. Winds and currents bring nutrient-rich water towards the surface, supporting abundant marine life. The sheltered shallows to the east contrast with the open ocean, and their shifting banks have long required careful navigation.
