Antarctica’s Salty Valleys Provide Clues To Martian Atmospheric Processes SpaceDaily

Chemists at the University of California, San Diego have discovered that the mysteriously high salt concentrations in exposed soils of Antarctica’s Dry Valleys are due in large part to biological sulfur emissions in the oceans surrounding the continent. Such observations have important implications in the search for evidence of past or present life on Mars, as well as on understanding the chemical interactions between the Martian atmosphere and the red planet’s surface.
