Dead Sea 342 parts per thousand (in 2002), and a temperature that swung between and . Underneath a zone of transition, the lowest level of the Dead Sea had waters of a consistent temperature and complete saturation of sodium chloride (NaCl). Since the water near the bottom is saturated, the salt precipitates out of solution onto the sea floor. Beginning in the 1960s, water inflow to the Dead Sea from the Jordan River was reduced as a result of large-scale irrigation and generally low rainfall. By 1975, the upper water layer was saltier than the lower layer. Nevertheless, the upper layer remained
Dead Sea a density of 1.24 kg/litre, which makes swimming similar to floating. The Dead Sea is receding at an alarming rate. Multiple canals and pipelines were proposed to reduce its recession, which had begun causing many problems. The Red Sea–Dead Sea Water Conveyance project, carried out by Jordan, will provide water to neighbouring countries, while the brine will be carried to the Dead Sea to help stabilise its levels. The first phase of the project is scheduled to begin in 2018 and be completed in 2021. In Hebrew, the Dead Sea is ' (), meaning "sea of salt" (Genesis 14:3). The
