Seminar Detail
Organic Biosignatures: Earthly biomarkers, analytical approaches, old rocks and meteorites
Presenter: Roger Summons ()

A NASA-sponsored Task Force on Biosignatures for Mars Exploration
met at UCSD February 2000 and included leading researchers in all facets of
biosignature detection. They examined a wide range of issues surrounding
the nature and measurement of various kinds of isotopic, mineralogical and
molecular signatures of life. This talk summarizes the finding of the group
working on molecular biosignatures and examines the intrinsic
characteristics of organic molecules that are constructed by living
organisms and discusses features in which these differ from organic
molecules that are produced in abiotic processes. The presentation also
addresses recent progress in the search for molecular biosignatures in
Archean sediments.

The Director’s Seminar series features talks from scientists who are invited by the NAI Director to present their research results to the community. A primary goal of the seminars is to encourage interdisciplinary collaboration across NAI teams and within the astrobiology community at large.
Team Overview Seminars describe the work of the fourteen NAI teams and NAI Central. They offer an opportunity to find out more about the science, E/PO and other activities being performed by the NAI teams and the NAI Central office.
The Forum for Astrobiology Research (FAR) provides an opportunity for graduate students to present their research results and to meet as a student community for networking and mutual support.
The University of Washington seminar series is hosted by the NAI Virtual Planetary Lab (VPL) team from the UW campus in Seattle.
