| Abstract: |
Groundwater was sample from wells in the riparian zone of a high permafrost (C3) and low permafrost watershed (C2) in Caribou-Poker Creeks Research Watershed in interior Alaska. Each sample was measured for a suite of solutes (anions, cations, dissolved organic carbon, total dissolved nitrogen, conductivity, pH). To analyze spatial and temporal patterns of solutes in riparian groundwater and to determine calculate groundwater inputs to stream chemistry.

C2 -- The tributary basins of Caribou Creek are all arbitrarily designated with a
"C". The C2 basin is the sub-basin with the least amount of permafrost of the CPCRW sub-basins. As such, it has been often been studied intensively in conjunction with C3, the sub-basin with the greatest amount of permafrost. The basin trends to the south, with well-drained slopes and permafrost-underlain treeless muskeg in valley bottom. Although an extensive fire history has not been done, there was probably a stand-replacing fire early in this century (ca. 1925), with some large white spruce stands that survived from the earlier vegetation.
