Serpentinizing Systems Science

Presenter: Alexis Templeton, Tori Hoehler & Jen Blank
When: January 31, 2017 9AM PST

Sponsored by the NASA Astrobiology Institute
Co-organized by Alexis Templeton, Tori Hoehler and Jen Blank


Compelling terrestrial evidence records active and ancient serpentinization, the process that occurs when ultramafic rocks come into contact with water. This process may have been active on the surface and subsurface of Mars, beneath the surface of icy satellites such as Enceladus and Europa, and beyond. On Earth, these geochemical interactions support distinct microbial ecosystems.

The purpose of this workshop is to highlight recent advances in understanding how Serpentinizing Systems function chemically and biologically within our Solar System.

For more information, of if you would like to contribute a pop-up talk, please contact the Workshop Organizers: Jen Blank ( or Tori Hoehler (

Pop-up talks, in this context, are 1-5 minute contributed presentations that will be scheduled in the final Workshop agenda to follow the listed speakers. Contributors may use slides (typically 1-3), which they should send to the organizers and to the NAI Technical Support personnel in advance.

There is wide latitude for the content of the pop-up talks, but they should follow the theme of the day of the Workshop.

Each day of this 3-day workshop will begin with an overview by a Theme Lead, followed by several invited talks (list below) and group discussion. Participants will be encouraged to contribute short, pop-up talks, and the workshop is open to all interested parties.

A short white-paper on emerging frontiers in Serpentinzing Systems Science will be crafted from the workshop content.
