What is Biogeoscience?
Biogeoscience is the study of the processes in and interactions among the Earth’s atmosphere, biosphere, hydrosphere, and geosphere. There are two key elements in the study of biogeosciences: (1) biogeophysics, the processes associated with the movement of water, mass, and energy within and across ecosystems, and (2) biogeochemistry, the processes related to the cycling of elements within and across ecosystems. The field of biogeoscience therefore provides the scientific basis for understanding the role of ecosystem processes in some of today’s most pressing environmental issues including climate change, deforestation, eutrophication of lakes and rivers, and the effect of sea level rise on coastal and estuarine ecosystems. Examples of research in the biogeosciences include, but are not limited to, the effect of vegetation and deforestation on the Earth’s climate and energy balance, the ability of terrestrial ecosystems to store rising concentrations of atmospheric carbon dioxide, and the role of soil microorganisms in regulating nutrient supplies that fuel terrestrial productivity.
The field of biogeosciences has emerged as one of the most important new areas for interdisciplinary research. In response, the two major scientific organizations in this area, the Ecological Society of America and the American Geophysical Union, have introduced new Sections that foster community interaction and research in this new and rapidly developing field. National research priorities, as reflected by new funding programs initiated by federal agencies, are increasingly focused on interdisciplinary themes related to biogeoscience. Such funding programs provide excellent opportunities for interdisciplinary Ph.D. research and the Boston University Biogeoscience Program is specifically designed to leverage and target these opportunities for students.
Biogeoscience at Boston University
The field of biogeoscience is driven by a diverse set of experimental, observational and modeling approaches. To advance, this field needs to develop interdisciplinary cooperation – training and collaboration – across these traditional disciplines. By virtue of its’ unique faculty composition, Boston University is able to provide a one-of-a-kind research and training program focused on interdisciplinary ecosystem processes. Specifically, faculty in the departments of Geography & Environment, Biology, and Earth Sciences have unique strengths in biophysical interactions and biogeochemical processes at the land-ocean and land-atmosphere interfaces, making BU a natural home for a program of this nature. The goal of Boston University’s Terrestrial Biogeoscience program is to integrate faculty and student research interests across these departments.
Research and teaching in the biogeosciences at Boston University is centered on ecosystem processes at the land-atmosphere and land-ocean interfaces. Taken as a whole, BU faculty interested in biogeoscience bring a depth and breadth of expertise that is unrivaled at other institutions in the United States. The department of Biology has faculty expertise in ecosystem science, terrestrial biogeochemistry and plant biology. The department of Earth Sciences includes faculty expertise in biogeochemistry, hydrology and the geomorphology of land and coastal systems. The department of Geography & Environment provides expertise in the physics of land-atmosphere interaction, physiological ecology, and remote sensing. By integrating existing strengths in biogeochemistry with biogeophysics, global-scale modeling, and remote sensing, Boston University is able to offer a Ph.D. research and training program that is unique both nationally and internationally. The Biogeosciences Program at Boston University fills a distinct, national-scale niche: a truly interdisciplinary research and teaching program in biogeoscience.
