Due to its extreme salinity and high Mg concentration the Dead Sea is characterized by a very low density of cells most of which are Archaea. We discovered several underwater fresh to brackish water springs in the Dead Sea harboring dense microbial communities. We provide the first characterization of these communities, discuss their possible origin,(More)
Within the hyper-arid to semiarid areas of Israel three experimental drainage basins varying in area, climate, monitoring duration and type have been being research-monitored. Lessons derived from a large number of published and ongoing research projects on these experimental basins focus on runoff and sediment in drylands. The effect of the spatial(More)
The Dead Sea region has faced substantial environmental challenges in recent decades, including water resource scarcity, ~1m annual decreases in the water level, sinkhole development, ascending-brine freshwater pollution, and seismic disturbance risks. Natural processes are significantly affected by human interference as well as by climate change and(More)
The overall aim of the this study, which was conducted within the framework of the multilateral IWRM project SUMAR, was to expand the scientific basement to quantify surface- and groundwater fluxes towards the hypersaline Dead Sea. The flux significance for the arid vicinity around the Dead Sea is decisive not only for a sustainable management in terms of(More)
16 This paper reports on bedload flux and texture monitored in a natural, steep, sandy 17 ephemeral channel draining a small gullied sandy watershed, the Barranca de los Pinos 18 (1.32 ha), Spain. Bedload flux was continuously monitored with two independent Reid19 type slot samplers; bedload texture was determined from the sediment collected in the 20(More)
