Karen Bartlett, Research Scientist
Research interests:
I'm interested in the interactions between the biosphere and the atmosphere,
particularly the magnitude of and controls on trace gas emissions (primarily
methane) and the sources of variability in atmospheric levels of methane.
Most of my work has focused on the role of natural wetlands as sources
of methane.

Research Interests: My current research interests focus on the biogeochemical dynamics of atmosphere/biosphere interaction. How does the biological mediation of geochemical cycles affect the distribution of mass on the surface of our planet and how does that interaction feedback upon the earth's physical processes. We want to make local scale experiments that are relevant to the extrapolation and quantification of micro scale processes to the planetary macroscale. We have studied the production, consumption and exchange of trace gases between the biosphere and the troposphere; especially methane (CH4), carbon dioxide (CO2), nitrogen oxides (N2O, NO) and methyl bromide (CH3Br).

Visiting Research Scientist, Complex Systems Research Center, Durham NH
I study the effects of land use change and agricultural intensification
in Central and South America on the function of ecosystems and the control
of atmospheric chemistry and composition. My research ranges from the
biological controls of trace gas emissions at the organismal level to
the estimation and modeling of regional and global trace gas and carbon
budgets.

in primary and selectively logged forest at La Selva, Costa Rica and at
the LBA sites in Para State, Brazil. Working with Brazilian undergraduate
and graduated students in field activities and research projects.

Ruth K. Varner, Research Scientist
Research Interest: The biogeochemical cycling of methyl bromide (CH3Br ) in soils has been the focus of much of my research. I am interested in determining the magnitude of the production and consumption of CH3Br in forest, agricultural, and flooded soils. I am currently studying the effects of temperature and water level on net flux of CH3Br in a local freshwater peatland, Sallie's Fen.
