Continental shelves/South west African continental shelves
The countries on the southwestern coast of Africa include (north to south) Cameroon, Equatorial Guinea, Gabon, Republic of the Congo, Democratic Republic of the Congo (Zaire), Angola, Namibia, and South Africa.
On the orthographic map of Africa on the left South Africa is the southern-most country outlined. Going northward along the southwest coast are South Africa, Namibia, Angola, Democratic Republic of the Congo (Zaire), Republic of the Congo (Congo), Gabon, Equatorial Guinea, and Cameroon.
Cameroon continental shelves
The map on the right shows the location of Bonga Field off Nigeria where colors browns to gray approximately represent areas near or above sea level during the last ice age (currently 1,000 meters up to sea level).
Angolan continental shelves
As with other bathymetric maps yellow is 2,000 to 1,000 meters depth and orange to red is 1,000 meters to sea level. This latter depth zone represents those areas most likely near, at or above sea level during the last ice age. The region of the map is centered on the Kwanza river continental shelves off shore Angola.
Namibian continental shelves
As with other near surface continental shelves, those off-shore of Namibia, in the sea-floor map on the right, yellow is 2,000-1,000 meters in depth, orange is 1,000 to near sea level, and red is just below sea level. Orange to red is 1,000 meters up to just below sea level. During the last ice age, features in orange to red were likely just below to above sea level.
South African continental shelves
Several features apparently could have substantial portions at or above sea level due to the previous ice age during the last 50 kyrs. These include the Madagascar Ridge, the Mozambique Plateau, the Southwest Indian Ridge, and the Del Cano Rise. The Kerguelen Plateau is closer to and likely an extension of the Antarctic continental shelves.
In the image on the left the light blue colors correspond to the zone from 1,000 meters to sea level.
