Application Of Avhrr To Monitoring A Climatically Sensitive Playa. Case Study: Chott El Djerid, Southern Tunisia. ...(Site not responding. Last check: 2007-10-09)
Abstract: The importance of monitoring changes in the levels of lakes within endorheic basins using remotely sensed data as a means of assessing changes in regional aridity is noted.
Large salt playas are highlighted as ephemeral lakes that can display extreme sensitivity to changes in regional rainfall patterns, and which commonly do not have extensively managed catchments.
To explore the application of high temporal frequency monitoring of salt playas using remote sensing, the Chott el Djerid, a large...

To explore the application of high temporal frequency monitoring of salt playas using remote sensing, the Chott el Djerid, a large salt playa situated in southern Tunisia was targeted.
A short time series of 39 Advanced Very High Resolution Radiometer (AVHRR; resolution 1.1 km at nadir) images of the Chott el Djerid (spanning 36 months between 1987 and 1990) were compiled along with climate information from a weather station at Tozeur.
Using image histogram manipulation, lake areas were extracted from the time series.

It is rather sure that the lake (marsh) Tritonis of antiquity is identical with the ChottDjerid in the South of Tunesia.
A thorough investigation of this landscape might be necessary.
North of the ChottDjerid near the town Gafsa there has been discovered an unique culture which is called after this town Capsien.

Enclosed basins of salt and clay accumulation may originate from numerous causes.
Tectonic causes include faulting, as in the East African Rift Valley and Death Valley, and warping, as in Lake Eyre in Australia, Lake Chad in central Africa, and Shatt al-Jarid (ChottDjerid) in Tunisia.
Wind deflation can produce shallow basins with downwind dunes, as in southeastern Australia.
Tozeur near the Chott El Djerid has a remarkable building-order; the stones are set in such a way that it create always some shadow.
In Tozeur we visit a little zoo with coke drinking camels, trained scorpions, snakes and the museum Dar Cheraiet where traditional furnitures and dresses are exhibited.
After the museum we have a long travel through the Chott El Djerid a salt-marsh for our destination Douz.

Ant assemblages at their dry limits: the northern Atacama Desert, Peru, and the Chott El Djerid, Tunisia
Ants do not occur in the rocky desert of the Nazca Plain, Peru, except in the vicinity of shrubs in outwash gulleys, where there are two species that have similar activity periods and microhabitats and exhibit interference competition.
Only one species of ant was found on the Chott El Djerid, Tunisia, a large, dry salt lake, devoid of vegetation.
