This progress report is a funding, extension request to continue the database work for the Hydrological and Geochemical Response and Recovery in Disturbed Arctic Ecosystems Program. Throughout the period from 1985 to 1992 the Department of Energy supported research on the hydrology and geochemistry of the headwater basin of Imnavait Creek has focused on the quantification of the input from atmospheric sources of biologically significant and other related chemical variables; the transport of these variables in surface and subsurface flow and their efflux from the basin; and the development of geochemical budgets. The acquisition of multi-year data sets (the longest and most detailed sets in the Arctic) have made it possible to define seasonal ranges and amplitudes; determine spatial and temporal relationships within the different flow compartments; to begin to model the pathways and rates of movement through and across different landscape units. The length of record has also made it possible to examine the quantity and influence of local and extra-regional additions.
