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.

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.
