Dynamic Interactions of Earth's Global Cycles

The field of biogeochemistry offers an interdisciplinary approach to study the interactions among the Earth’s ecosystems, land, atmosphere, and oceans. PCCRC projects bring together biogeochemists, land modelers, and ecologists to explore a variety of global change issues including climate change feedback effects, oxidation capacity of the atmosphere, land use change, nitrogen cycling, and the impacts of humans on the environment.  

Current Research Projects

Biogenic Volatile Organic Compounds and their Impacts in a Changing Temperate Forest: This project is part of a long-term research initiative designed to measure emissions of biogenic volatile organic carbon compounds (BVOC) and to determine the impact of these compounds and their associated reaction products on climate.

Quantifying Climate Feedbacks from Abrupt Changes in High-Latitude Trace-Gas Emissions: The overall goal of this project is to quantify the potential for threshold changes in natural emission rates of trace gases, particularly methane and carbon dioxide, from pan-Arctic terrestrial systems under the spectrum of anthropogenically forced climate warming, and the extent to which these emissions provide a strong feedback mechanism to global climate warming.
