AND RESEARCH AREAS:
Research has focused on the biogeochemical transformations of carbon with an emphasis on process-oriented studies of the fate of organic carbon in surface environments. Methanogenesis, methane oxidation, and the influence of macrofauna on organic carbon diagenesis are some of the processes investigated in field areas ranging from the North Carolina slope to the Amazon shelf. Current projects involve the evolution of organic carbon as particles move from exposed bedrock on land to ultimate burial at sea. Riverine systems in northern California, New Zealand and Papua New Guinea are under investigation.
