Salt Flats of Chott el Djerid and Sediments Along Coast of Tunisia

Libya and Tunisia - April 14th, 2012

Bright blue and green sediments and phytoplankton can be observed in the Gulf of Gabes and all along the shores of Tunisia, stretching to the Libyan coastline as well. The color is darker green in the Gulf of Gabes and around the Kerkennah Islands, and bright blue east of Djerba.

Further inland, the Chott el Djerid appears as a large, dark tan area. It is a large endorheic salt lake in southern Tunisia and the largest salt pan of the Sahara, with a surface area of over 7,000 km2. South of Chott el Djerid, the Grand Erg Oriental desert begins.

Tunisia and Algeria - November 23rd, 2011

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

Visible to the west of the gulf, further inland, is a large tan area, known as the Chott el Djerid. It is a large, endorheic salt lake in southern Tunisia and the largest salt pan of the Sahara Desert. The golden area of desert south of the Chott el Djerid is the Grand Erg Oriental, a sand dune sea stretching across Algeria to Tunisia.

Tunisia - June 21st, 2011

The Italian island of Sicily is visible in the upper right corner of this image, a relatively short distance from Tunisia, in North Africa.

The northern coast of Algeria (west) and Tunisia (east), along the Mediterranean Sea, shows some green vegetation, while the land to the south is mostly  desert.

Most of the sandy desert visible is part of the Grand Erg Oriental.  Just north of the erg is the Chott el Djerid, a large endorheic salt lake (usually a rather dry salt pan)  in southern Tunisia.

Algeria and Tunisia - February 11th, 2011

The northern coast of Algeria (left) and Tunisia (right), along the Mediterranean Sea, appears green and vegetated in contrast with the arid, sandy desert to the south.

In the full image, many individual rows of sand dunes can be concerned in the Grand Erg Oriental, particularly in the area of orange-colored sands. Just north of the erg is the Chott el Djerid, a large endorheic salt lake in southern Tunisia. It is the largest salt pan of the Sahara Desert.

Algeria and Tunisia - December 27th, 2010

The Grand Erg Oriental is a large erg or “field of sand dunes” in the Sahara desert. It covers an area some 600 km wide by 200 km north to south.

The majority is situated in the Saharan lowlands of northeast Algeria,  but the erg’s northeastern corner spills over into neighbouring Tunisia.

To the north of the erg, the Aurès mountains provide abundant runoff. These waters feed the artesian aquifer of the Jerid, despite its surface covering of salt lakes.
