Saltiest body of water
Last updated: May 2, 2019 at 3:34 am
433 parts per thousand (ppt, ‰) — Gaet’ale Pond, Ethiopia. It is approximately 12 times saltier than sea water (35 ppt), and its temperature is 60°C (140°F). The water is saturated with salts, i.e. it isn’t possible to dissolve more salt. The pond reportedly appeared after an earthquake in 2005.
(#2) The salinity of Don Juan Pond, Antarctica, is 403 ppt. Although its average depth is less than 30 cm (1 ft) and the surface temperature can reach -53°C (-63.4°F), the pond never freezes.
(#7) The salinity of the Dead Sea can reach up to 337 ppt in the top 35 m (115 ft).
(#15) The salinity of the Atlantic and Pacific Oceans reaches up to 35 ppt.
