Organic biosignatures for microbial processes in the
terrestrial marine subsurface

The NAI Subsurface Biospheres is studying ecosystems in the marine
subsurface as potential analogs to habitats of life on other planets. When
analyzing organic compounds as markers for life and the related processes in
materials returned from other planetary bodies, the main challenge will be
the distinction of biotically and abiotically produced compounds. By
contrast, when studying microbial processes in geological systems such as
marine sediments that are nourished by organic compounds derived from
photosynthetic primary production, it is important to develop robust
criteria for the identification of signatures from current activity and
select against those from past activity. The presentation will provide an
overview on how we decode information on processes in the marine subsurface
from organic molecules such as intact membrane lipids and
low-molecular-weight organic metabolites.

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.
