Linda Kah is a leading expert on the evolution of the Earth during the Mesoproterozoic (1.6 to 1.0 billion years ago). Her research focuses on reconstructing oxygenation of the Earth's oceans and atmosphere and interpreting the effects on biological activity in the oceans. More recently, she has expanded her interest in ancient sedimentary environments to the surface of Mars, where she is investigating potential habitable environments as a co-investigator on the Mars Science Laboratory mission. In 2014, Kah was named a fellow of the Geological Society of America.
Topics of expertise: Mars, geochemistry, sedimentary geology, and earth evolution
NASA has responded to a cheeky request from the National Trust for Scotland (NTS) for free entry and parking for its members at some locations on Mars.The charity posed the question in a letter to the US space agency after learning that geology on the planet had been given Scottish names.
