Biogeochemistry & Environmental Microbiology

Our interdisciplinary research group in Biogeochemistry and Environmental Microbiology studies the interactions between microbial processes and geochemistry in aquatic and terrestrial systems. Topics include microbial metabolism and element cycles; biodegradation of pollutants; environmental genomics of microbial consortia; greenhouse gas cycling; and the environmental fate of agricultural fertilizers.

Effects of sea-level rise on tidal marsh ecosystems

8/28/09 
The coastal wetlands in the U.S. are essential to the ecological and economic health of many communities. They serve as habitats for many birds and animals, they filter out many pesticides and pollutants sent "downriver," and they protect shorelines from the worst impacts of storms and flooding. However, predicted rising sea levels due to climate change have raised many questions about what will happen to the nation's shorelines. Through the support of the US Environmental Protection Agency, US Department of Energy and the National Science Foundation, Professor Chris Craft and a team of researchers examine the coastline marshes of the southeast to determine their susceptibility to climate change. They came away with a model that may predict the future picture of our nation's coastal wetlands.
