As part of the Western Arctic Shelf-Basin Interactions Project initiated by NSF and the Office of Naval Research, the Maryland Organic Geochemistry and Ecology Laboratory (MOGEL) at UMCES/CBL is investigating organic carbon cycling and the potential impacts of climate change on biogeochemical processes.  The Arctic Ocean receives carbon through both new production in marine waters as well as land derived carbon via river runoff and coastal erosion.  Professor Rodger Harvey and doctoral student Laura Belicka are detailing the sources of carbon that gets preserved in ocean sediments which provides a record of historical conditions and can be used to understand how climate change is affecting the production and recycling of carbon.
