Hot spring in the pond

Gaet'ale Pond is a small hypersaline lake located near the Dallol crater in the Danakil Depression (Afar Region, Ethiopia). It is located over a hot spring of tectonic origin and has no apparent inlet or outlet streams. The water of Gaet'ale Pond has a salinity of 43%, making it the saltiest water body on Earth.[1]

Location and origin

Gaet'ale Pond is the largest of a series of small ponds located approximately Шаблон:Convert southeast of Dallol springs. It is crescent-shaped with a diameter of about Шаблон:Convert.

According to residents of the nearby village of Ahmed'ela, an earthquake in January 2005 reactivated a thermal spring and the pond was created.[2] For this reason, its temperature of Шаблон:Convert is hotter than the environment.[3]

Composition of the water

The salts in the water of Gaet'ale Pond are mainly composed by calcium chloride at 2.72 mol/kg and magnesium chloride at 1.43 mol/kg. It also contains small amounts of Na+, K+ and NO2 ions. The total amount of dissolved solids content is 433 g/kg, or 43.3%. It also contains traces of iron(III) that form a complex with chloride, giving the water a characteristic yellow color.[1]

Bubbles of odourless gas are emitted from the lake surface. It is likely volcanically-produced carbon dioxide. Bird and insect corpses have been found around the pond, and it has been proposed that the gas may be harmful for small animals or humans.[3]
