Biogeochemistry of Glaciers

This project is quantifying water sources and solute fluxes in the Wolverine Glacier Basin

Abstract


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 nutrients are likely to impact productivity in both freshwater and marine environments, our lack of understanding on these processes limits our ability to predict their changes and the likely effects on downstream ecosystems.
