Research Abstract
Global cycles of biogeochemically important elements Information and Figures. The role and importance of anaerobic proceses and anoxic environments in the global carbon cycle. The role of microbial processes as controls and feedbacks in global climate change.

Methane biogeochemistry and organic carbon storage in high deposition rate marine sediments and anoxic marine basins. Methane oxidation as a flux control and global sink in marine systems. Rate measurements of anaerobic methane oxidation using labelled methane (3H and 14C) tracers and extent of reaction estimates using stable isotope (2H, 13C) distributions. Methane oxidation as a control on emissions from decomposing methane clathrates. Laboratory studies using externally controlled partial pressures of hydrogen to determine whether anaerobic methane oxidation is conducted by methanogens operating in reverse.

Importance of high-latitude terestrial environments in the global carbon and atmospheric methane budgets. Response of high-latitude environments to climate change. Time series measurements of trace gas fluxes from wetland, tundra, and boreal forest systems. Biogeochemical processes at the oxic:anoxic interface in soils. Importance of aerobic methane oxidation in wetland and soil systems as a sink, flux control, and possible feedback. Detrmination of kinetic isotope effect for methane oxidation from soil profiles. Laboratory and field manipulation studies of methane oxidation sensitivity to moisture water table level, and temperature changes. Pulse labelling (14CO2) experiments to determine the role of recently-fixed photosynthetic carbon in wetland methane production and release. Biosphere 2 methane budget studies.
