Video: Methane on Mars, a SETI Talk by Giuseppe Etiope

In this video, Giuseppe Etiope addresses the fundamentals of methane seepage, its potential occurrence on Mars, and possible detection techniques.

The occurrence of methane (CH4) in the Martian atmosphere may imply active geological sources on the red planet, i.e. gas emission structures in the Martian soil and subsoil similar to what we see on Earth. In other words, gas seepage, a process well known on Earth, should exist on Mars. The concept of gas seepage, although obvious to many geologists, may be less obvious to the Mars methane science community. In this video, Giuseppe Etiope (DCO Deep Energy Community) addresses the fundamentals of seepage, its potential occurrence on Mars (via microseepage, mud volcanoes, faults, and degassing from serpentinized rocks), and possible detection techniques.

Giuseppe Etiope is a senior researcher, geologist, at the Istituto Nazionale di Geofisica e Vulcanologia in Rome, Italy. He works on the origin, occurrence, and migration of gas in the geosphere, with particular reference to biotic hydrocarbons in sedimentary basins and abiotic gas in serpentinized ultramafic rocks. He studies the origin of methane, gas seepage phenomena and their implications for the environment, energy resource exploration and planetary geology (methane on Mars).
