Phytoplankton Bloom off Angola-Namibia Coast18.7S 16.2E
Part of the border between Namibia (below) and Angola (above) can be easily identified here as a straight line across the land in the upper half of the image.
Two geographical formations of note can also be seen: the green Etosha pan, a large endorheic salt pan south of the border, and the northern part of the orange Namib Desert, in the lower right quadrant. The close-up focuses on the 120-kilometre-long (75-mile-long) dry lakebed and its surroundings, which are protected as Etosha National Park.
Two other phenomena of a more temporary nature include a semi-circular phytoplankton bloom off the coast between the Namib Desert and the Etosha Pan, and a faint wisp of smoke blowing across the border in the upper right quadrant. Both are best visible upon opening the full version of the main image.
