Biogeochemistry of Carbon and Nitrogen in Aquatic Environments
Although it is clearly recognized that microorganisms play an important role in the transformation of carbon- and nitrogen-containing compounds in aquatic habitats, very little is known about the exact nature of these tranformations in either pristine or contaminated environments. Within the context of in situ environmental conditions, the mechanisms, pathways, rates, and factors controlling carbon cycling by microorganisms are poorly understood; however, these particular processes can significantly affect the entire range of biogeochemical and geochemical processes occurring within the aquatic environment. The objectives of this project are to study the mechanisms, pathways, and rates of transformation of carbon and nitrogen compounds (natural and contaminant) mediated by microorganisms in aquatic habitats; to identify some of the factors controlling these transformations; and to examine the effect that these transformations have upon other biogeochemical processes. For additional information, see project's home page.
