Sleepers River Research Watershed
The Sleepers River Research Watershed in Danville, Vermont has been the site of active hydrologic research since 1959, when the Agricultural Research Service (ARS) of the U.S. Department of Agriculture (USDA) established a research program in the watershed. The Sleepers River site is now operated by the USGS, in cooperation with several other Federal agencies and universities.
Mountains to sea – fluvial transport of carbon and nutrients and effects on ecosystems and people
Stream transport (lateral transfer) of carbon remains a poorly understood flux within the global carbon budget. This research addresses the need to refine our knowledge of both provenance and transformations of Dissolved Organic Matter (DOM) as it moves from mountains to sea. Interpreting shifts in carbon quality with increasing stream order, and how these patterns change with variation in...
Biogeochemistry of glaciers
Significant change to the Arctic and sub-arctic water cycle is underway, impacting hydrologic and biogeochemical fluxes. In southcentral Alaska, glacier mass loss, changes to precipitation (including the rain/snow fraction), thawing ground ice, and vegetation encroachment will change both magnitude and timing of water and solute fluxes downstream. Although altered fluxes of limiting...
