Dissolved organic carbon in Alaskan Arctic snow: concentrations, light-absorption properties, and bioavailability ...
Dissolved organic carbon (DOC) plays an important role in the carbon cycle, radiative forcing, and biogeochemistry in cryospheric regions. In this study, concentrations, light-absorption properties and bioavailability of DOC from snow cover in Alaska were characterized. Results indicated that averag...
