Biogeochemical investigations examine the diverse interactions between biological and geological ecosystem components.  Our current research activities examine how sensitive alpine and polar ecosystems respond to physical, climatic, and hydrologic changes on time scales ranging from days to millions of years.  Three main research themes have evolved from this overall theme.
