Facility for Biogeochemical Research on Environmental Change and the Cryosphere
Our research program strives to increase our understanding of the processes of carbon (C) and nitrogen (N) cycling in terrestrial ecosystems, and how human-induced disturbance influences these processes. The perturbation of these cycles has enormous consequences to humans.
The key research questions are -
- How do forest management practices and other disturbances particularly non-stand-replacing events, alter rates of C exchange with the atmosphere?
- How does conversion of former agricultural land to forest influence soil C storage?
- What is the fate of different forms of N added to forest ecosystems, and how does this exogenous N influence rates of C exchange between the forest and the atmosphere?
Human disruption of biogeochemical cycles, particularly those caused by land-use change, can severely alter the integrity of terrestrial ecosystems and their ability to provide critical ecosystem services to society. Disruption of the global carbon cycle and the rise in atmospheric carbon dioxide is disrupting the climate system. Enhanced inputs of nitrogen to terrestrial ecosystems can have a severe impact on the health of both aquatic and terrestrial ecosystems, while also contributing to global climate disruption.
Students and Dr. Scott are working to improve our understanding of critical processes in these biogeochemical cycles, how they are being altered by human activity, and how terrestrial ecosystems might be more effectively managed to help mitigate human impacts while still providing critical ecosystem services.
Our research varies from site-specific studies to large scale investigations facilitated by remote sensing, geographic information systems, and simulation models. We try to make our research results relevant and available to the general public and to policy-makers, with the hope that we can provide key scientific information needed for the development of sound environmental policy.
Graduate Student Research Opportunities
There are student research opportunities available now. Contact Dr. Neal Scott (email@example.com) or the Geography Department for more information. I am particularly looking for students who want to work on soil biogeochemistry and ecosystem gas exchange in High Arctic ecosystems at the Cape Bounty Arctic Watershed Observatory.
