Award Description: NSF 06-563 Geobiologyu and Low-Temperature Geochemistry
Project Description: The objective of this award is to enhance our understanding of the role of microbes in anoxic Fe-rich aquatic environments. Considerable uncertainty currently surrounds the role of anoxygenic photoferrotrophs in the biogeochemistry of the Archean and Proterozoic oceans and their possible role in the precipitation of the Banded Iron Formations. A related carbon cycling question is whether, in the absence of oxygen and sulfate, methane could have been oxidized in those early Fe-rich waters by iron oxides. The Fe-rich anoxic waters of Lake Matano, Indonesia, appear to be an excellent modern analogue for the early oceans. We will test the hypotheses that anaerobic processes (both photoferrotrohy and anaerobic methane oxidation) are substantial facets of the carbon cycle in this lake. We will quantify these processes using field and laboratory methods and reactive transport modeling.
Infrastructure Description: N/A
Jobs Summary: Job numbers are reported as full time equivalents (FTE). For purposes of this report, FTE is expressed as the cumulative total number of hours worked, divided by the total number of hours in a full-time schedule from the start date of the award. The job figure contains jobs directly charged to the prime award, first-tier subawards, and vendor payments greater than $25,000. The data for this report was collected from the university payroll system, subawardees, and vendor contacts. Job creation and retention are represented as a single number. This award specifically created and/or retained jobs with the following title(s):Graduate Research Assistant (Total jobs reported: 1)
Project Status: Less Than 50% Completed
