The Department of Energy (DOE) operates Brookhaven National Laboratory (BNL) with its many unique research facilities and programs. One of the DOE?s major strategic missions is the Terrestrial Carbon Processes Program that studies the global production and transport of anthropogenic CO2 and its effects on climate and health. BNL?s Environmental Sciences Department responds to this mission and the research of Wielopoloski?s group in the Environmental Research and Technology Division are closely tied to this goal. Through new instrumentation, focused measurements, and modeling, they aim to determine the in situ carbon content of soils, locally and over large tracts of land. This research, though still in its early stages, is very promising, offering levels of precision not previously attainable, along with speed and lower costs. This meeting will bring together experts in instrumentation and field measurements from other DOE laboratories, universities, and the United States Department of Agriculture to evaluate and explore the novel methodologies and to assess their advantages over conventional methods.
