In the upper left quadrant, bluish sediments can be observed around Djerba, the largest island of North Africa, located in the Gulf of Gabes, off the coast of Tunisia. The island has a surface area of 514 km²,

Visible to the southeast is the Haruj, a large volcanic field spread across 45,000 km2 (17,000 sq mi) in central Libya.

Tunisia - July 21st, 2010

Several cities and towns can be seen near the coast of Tunisia. The most prominent is Ben Gardane (lower right quadrant), a coastal town in the eastern part of the country, close to the border with Libya.

The town is situated just south of the Bahiret el Bibane, a lagoon whose wetland is recognized internationally by the Ramsar Convention.

Another body of water, the Gulf of Boughrara, can be seen in the upper lefthand corner. The town of Zarzis is situated to its east, along the Mediterranean Coast, and the island of Djerba is situated to the north of the gulf.

Although the coastal areas visible in the thumbnail are mostly flat, the elevations to the south are higher, as can be seen upon opening the full version of this orthorectified image.

Kerkennah Islands and Djerba Off Tunisian Coast

Tunisia - December 16th, 2009

Tunisia - December 16th, 2009

Both the Kerkennah Islands (above) and the island of Djerba (below) are surrounded by greenish tan waters. This coloration may be partially caused by sediments and partially caused by algal growth, as two species of green algae tend to invade this coastal region.

The Kerkennah Islands are a group of islands lying off the east coast of Tunisia in the Gulf of Gabes. The islands are low-lying, at no more than 13 metres above sea level. The archipelago has an area of 160 km2 and a population of 14,400 as of 2006. Djerba, also located in the Gulf of Gabes, is the largest island off North Africa at 514 km². Its largest city is Houmt-Souk, with a population of around 60,000.
