Mediterranean – May 22nd, 2013

A thick plume of dust blows off the coast of Tunisia and over the Mediterranean Sea, fanning out as it spreads towards Sicily, in southern Italy. The dust obscures much of the Gulf of Gabès, the Kerkennah Islands and Djerba.

Tunisia – February 2nd, 2013

Most reliable models of climatic observation and forecast show that the south of the Mediterranean perimeter is threatened by important variations of environmental conditions. In parts of the Kerkennah archipelago, which is visible here off the coast of Tunisia, ringed by bright green and brown sediments, changing marine conditions and overfishing have caused a decrease in fish quantity and favoring of agriculture over fishing. There has also been an enlargement of sebkhas (low, salty lands that are liable to flooding hazards) that might likely be caused by climatic and environmental evolution like sea level rise and subsidence, making such areas more vulnerable to sea surges (click here to read more).

Tunisia – December 1st, 2012

Near the center of this image is the Gulf of Gabès, a gulf on Tunisia’s east coast in the Mediterranean Sea, off North Africa. The gulf roughly spans the coast from the town of Mahrès in the Sfax Gouvernorate to the island of Djerba.  Here, greenish phytoplankton and sediments can be seen in the gulf, spreading off the northwest coast of Djerba, and surrounding the Kerkennah Islands.

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.
