Metalrich Brines In The Red Sea 171 World Ocean Review

A 200-metre-thick layer of extremely salty, heavy water collects in these basins in the way that a haze of fog lies in a valley. With a temperature of over 60 degrees Celsius, this water comes from salt-rich rock layers on the flanks of the Red Sea and is concentrated here. Its salinity of around 26 per cent is 7 times as salty as normal seawater.
