Sand dune dynamics performs a key position in lots of arid deserts. This quantity presents a synthesis of a selected sand dune atmosphere, the Nizzana website within the Negev barren region. Describing its weather and geophysical/geochemical houses of soils, geological historical past, natural world, and past/present land-use styles, it elucidates ecological and geomorphological strategies and their interrelations, in response to long term tracking, in situ experiments and satellite tv for pc imagery. specific realization is interested in the impression of the topsoil organic crust in controlling water availability at local/regional scales. The interdisciplinary procedure followed for this reason learn bargains an excellent instance of a hugely complicated and dynamic approach, that can simply be utilized to different sandy ecosystems.

This is a precious resource of knowledge for soil ecologists and microbiologists, conservation biologists, wasteland ecologists and geographers, geomorphologists, soil scientists and climatologists, academics, coverage makers and others attracted to deserts and desertification.

This fact supports our assumption that the sand becomes redder with time. The distinct sand dune morphology of the Haluza-Agur Sands supports the interpretation that it is a discrete dunefield. According to Fig. 3, it is plausible that the HaluzaAgur Sands overlie sand type 1, and that some of sand type 1 has mixed with sand type 3. 89 at 20 °C (Griffiths 1967). The amount of iron in the clay coating of the sand grains was extracted for all the samples by using the sodium dithionite-sodium citrate extraction method (Mehra and Jackson 1960; Smith and Mitchell 1987).

In the Nahal Sekher area (Goring-Morris and Goldberg 1990). 2 The Sand Red Colour and its Implications The Negev aeolian sand shows different intensities of redness, with some variation in the hues because of the content of iron-oxide minerals. If there is a common source of all the sand and the climate is homogenous, we can assume that the different hues of red indicate different ages, as has been argued by many (Norris 1969; Folk 1976b; Walker 1979; Gardner and Pye 1981; Wopfner and Twidale 1988; White et al.
