Namib Desert - May 13th, 2009

The Namib Desert, which appears  orange and rusty red, stretches 2000 km (1200 mi) along the southwestern African coast, where a burning desert touches an icy sea. In contrast to its length, the average width of the desert is only 113 km (70 mi).

The hyper-arid Namib ecosystem is greatly affected by ocean winds and the Benguela Current. They temper the climate of the coastal desert, bringing life to the shores, and allowing for sediments deposited into the ocean to be carried back inland to form the Namib’s extensive dunes, the highest in the world.

These dunes are surrounded by arid plains, which never receive enough rainfall to permit grasses and shrubs to gain a foothold and colonize them.

Although there are other coastal deserts bounded by cool ocean currents, the Namib is the only desert in the world where endemic flora and fauna have evolved in virtually vegetationless dunes.

Bakassi Peninsula, Cameroon

Cameroon - February 15th, 2009

Here, a section of the coastline of Cameroon along the Bight of Bonny and part of the Gulf of Guinea is visible.

The peninsula in the upper left quadrant is named Bakassi.  It consists of a number of low-lying, largely mangrove covered islands covering an area of around 665 km².  It is currently ruled by Cameroon following the transfer of sovereignty from neighboring Nigeria.

Bakassi is situated at the extreme eastern end of the Gulf of Guinea, where the warm east-flowing Guinea Current meets the cold north-flowing Benguela Current. These two great ocean currents interact creating huge foamy breakers which constantly advance towards the shore, and building submarine shoals rich in fish, shrimps, and an amazing variety of other marine life forms.

The last time this area was observed by radar, strong outflow from the rivers could be seen. Here, the currents created by the river water are less evident.

The large, active Mount Cameroon is visible towards the bottom. Upon opening the full image, part of the rim of a sunken volcano on Bioko Island (part of Equatorial Guinea) at the very bottom.
