 It has the second highest total dissolved solids on record, with greater salinity than the Dead Sea or Lake Assal (Djibouti) (the same is true for Lake Vanda and perhaps other lakes in the McMurdo Dry Valleys).Salinity varies over time from 200 to 474 g/L, dominated by calcium chloride, and is over 18 times the ocean's salinity and 1.3 times that of the Dead Sea.It is the only Antarctic hypersaline lake that almost never freezes.
