Quick Answer
Don Juan Pond in Antarctica has a salinity of about 44 %, making it the saltiest body of water.
The Full Story
Don Juan Pond, a small, shallow hypersaline lake in the McMurdo Dry Valleys of Antarctica, has a salinity of approximately 44 % — about 12 times saltier than seawater and too salty to freeze even at −50 °C. Its extreme salinity comes from calcium chloride concentrated by evaporation. The Dead Sea (about 34 % salinity) is the best-known hypersaline body of water. Lake Assal in Djibouti (about 35 %) and Gaet'ale Pond in Ethiopia (possibly over 40 %) are also extremely salty.
Key Facts
1.Don Juan Pond is only about 10 cm deep.
2.Its water would taste extremely bitter, not just salty, due to the calcium chloride.
3.Scientists study Don Juan Pond as a potential analogue for briny environments on Mars.
