Tunisia - September 1st, 2009

The peninsula of Cap Bon in far northeastern Tunisia is flanked by the Gulf of Tunis to the west and the Gulf of Hammamet to the east.  Tunis, the capital city of Tunisia, appears here as a grey area at the southern edge of the Gulf of Tunis.

In this image, the Gulf of Tunis is greenish in color from algal growth or sediments. The rest of the visible shoreline, including that of the Gulf of Hammamet, is mostly clear.

Moving inland south of the peninsula is a white salt lake called Sebkhel de Sidi El Hani. The site, the third-largest salt-lake in Tunisia, is located 25 km south-west of Sousse and 20 km east-south-east of Kairouan.

It usually dries out in summer, but occasionally retains water all year. Salinity is very high and salt crystals sometimes remain on the substrate even when there is water in the lake.
