Biogeochemistry examines the role of biological processes in mediating the chemical and geological dynamics of the Earth’s atmosphere, hydrosphere and lithosphere. It is an inherently interdisciplinary science and UGA Marine Sciences faculty are actively involved in areas of biogeochemical research including aquatic photochemistry, the exchange of trace gasses between the ocean and atmosphere, nutrient cycling, organic matter degradation, and the use of biomarkers. This work takes place in coastal environments such as salt marshes, extreme environments, the open ocean, and ocean sediments. The integrative nature of this work requires the application of tools from a wide range of disciplines such as microbiology, geochemistry, ecology, hydrology, mathematics and physics.
