Golden Sands of the Grand Erg Oriental, Algeria and Tunisia

Tunisia and Algeria - October 13th, 2011

Greenish sediments can be seen in the Gulf of Gabes off the coast of Tunisia between the Kerkennah Islands, an archipelago with an area of 160 km2, and Djerba (south of the former), the largest island of North Africa at 514 km².

The large tan area inland, west of Djerba, is the Chott el Djerid, a large endorheic salt lake in southern Tunisia. It is the largest salt pan of the Sahara Desert. Moving southward, one comes to the golden yellow expanse of the Grand Erg Oriental, a sand dune sea stretching across Algeria to Tunisia.

Tunisia - July 4th, 2011

Visible off the coast of Tunisia in this image are the Kerkennah Islands (top right corner), an archipelago with an area of 160 km2, and Djerba (south of the former), the largest island of North Africa at 514 km², located in the Gulf of Gabes, off the coast of Tunisia.

Moving inland, west of Djerba, is the Chott el Djerid, a large endorheic salt lake in southern Tunisia. It is the largest salt pan of the Sahara Desert. South of this salt pan is the Grand Erg Oriental, a large sand dune sea.

Dust Blowing Off Coast of Tunisia and Libya

Tunisia - November 28th, 2010

Dust blows off the southeast coast of Tunisia (above left and center) and northwest coast of Libya (right), over the Mediterranean Sea.

The dust blows northeastward, creating a translucent veil over the Kerkennah Islands (above, near the eastern coast of Tunisia) and the island of Djerba (below, near the border with Libya). In the lower left quadrant, a large sand dune sea (erg) extending from Algeria into Tunisia can be observed.

Kerkennah Islands and Djerba Off Tunisian Coast

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.

Green Waters Around Djerba and the Kerkennah Islands, Tunisia

Tunisia - September 24th, 2009

The water around the shores of eastern mainland Tunisia, the island of Djerba (below) and the Kerkennah Islands (above), and in the Gulf of Gabès (center left) and Gulf of  Boughrara (below Djerba) show various shades of green, ranging from light and bluish to dark and brownish.

Some of the dark green color may be caused by two species of green algae that have a tendency of invading the coast of Tunisia and are often found around the Kerkennah Islands.
