Salt Flats of Chott el Djerid and Sediments Along Coast of Tunisia33.9N 10.3E
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.
