Seminar Detail
Linking Microbial Behaviors to Microbialite Morphology
Presenter: Dawn Sumner (University of California, Davis)

Stromatolite morphology is commonly attributed to environmental factors, and demonstrating the roles of microbial communities in the formation of ancient stromatolites is extremely challenging. However, modern microbial mats show diverse and sometimes intricate morphological features that reflect detailed ecological processes. Mats that form in low flow, low sedimentation environments commonly develop topography that reflects specific microbial behaviors. When one compares them to ancient microbialites that formed in similarly low flow, low sedimentation environments, there are some striking morphological similarities that may allow us to extract substantially more detailed ecological data from the rock record. I will present new results from studies of modern mats growing in ice-covered Antarctic lakes and compare their morphology to Archean microbialites with overlapping properties.

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.
