DALLOL

  • One of Earth’s most extreme environments,  Dallol is incredibly hot, salty and acidic. Its ponds  extend across a volcanic crater, in the Ethiopian  Danakil depression, filled with salt, toxic gases and  boiling water in response to extreme  hydrothermal activity.
  • Published journal: Nature Ecology and  Evolution.

DALLOL

  • The researchers, including those from the Spanish Foundation  for Science and Technology (FECYT), said Dallol’s landscape  extends over a volcanic crater full of salt, constantly releasing  toxic gases with water boiling in the midst of the intense  hydrothermal activity.
  • They said it is one of the most torrid environments on the planet  with daily temperatures in winter exceeding 45 degrees Celsius.
  • The landscape, the researchers said, had abundant hypersaline and  hyperacid pools, with pH — which is measured on a scale from 0  (very acidic) to 14 (very alkaline) — even hitting the negative mark.

POINT TO NOTE

  • “In addition, our study presents evidence that there  are places on the Earth’s surface, such as the Dallol  pools, which are sterile even though they contain  liquid water,” stresses Lopez Garcia.
  • This means that the presence of liquid water on a  planet, which is often used as a habitability  criterion, does not directly imply that it has life.

NOTES

  • In this study, it is found that, in the hyper acid and  hyper saline pools, nor in the Black and Yellow lakes  of Dallol but found few salt-loving microorganisms  in the desert, and the saline canyons around the  hydro thermal site.
  • The Black and Yellow lakes of Dallol which are rich  in magnesium.

WHAT EXACTLY IS DALLOL?

  • Dallol is a cinder cone volcano in the  Danakil Depression, northeast of the Erta  Ale Range in Ethiopia.

POINT TO NOTE

  • The term Dallol was coined by the  Afar people and means dissolution or  disintegration, describing a landscape  of green acid ponds (pH-values less  than 1) and iron oxide, sulfur and salt  desert plains.
