Peatlands are oxidizing, subsiding, releasing carbon dioxide, burning, and emitting huge plumes of smoke. With data from our unique field stations in Borneo, we have developed a comprehensive theory to explain the coupled ecological and hydrologic processes that control the accumulation and loss of peat, and the accompanying carbon fluxes, from tropical peatlands. This quantitative…

We are critically evaluating Carbon Capture and Sequestration (CCS) as a technology for reducing carbon emissions. We are uniquely positioned to evaluate CCS as a climate change solution because of our unique combination of independence and experience in the field. We differ from most researchers working on CCS because we are not funded by oil companies. …

We combine field experiments with numerical modeling to study seawater-groundwater interaction over tidal, lunar, and seasonal cycles. Understanding the physics of flowing water provides the foundation for understanding nutrient and contaminant fluxes to the ocean, as well as the capacity of coastal sediments to filter seawater that circulates through the subsurface.  We are now focussing…

Over one-hundred million people in Bangladesh, India, Nepal, Pakistan, Cambodia, Vietnam, and Myanmar are drink dangerous concentrations of arsenic from wells. Our work is focused in Bangladesh where tens of millions of recently-installed wells provide drinking water for over 130 million people. We combine hydrologic and biogeochemical analysis to elucidate processes that mobilize arsenic from…
