Many residents of Northern regions do not have access to municipal utilities. As such, rainwater catchments are commonly used as an untreated source of drinking water. The water quality in rain catchments depends on the materials used to construct the catchment, the frequency of rainfall, the amount of water collected, the quality of the rainfall, human and animal activity in the surroundings, and the duration of the water storage. The most problematic contaminants in rainwater catchments are bacteria, volatile organic compounds (VOC), and metals such as lead, copper, and zinc. The goal of this project was to help identify the frequency and magnitude of metal contaminants in Alaskan rainwater catchments. Over 50...

Many waterbird species utilize a diversity of aquatic habitats; however, with increasing anthropogenic needs tomanage water regimes there is global concern over impacts to waterbird populations. The federally threatened pipingplover (Charadrius melodus; hereafter plovers) is a shorebird that breeds in three habitat types in the Prairie PotholeRegion of North Dakota, South Dakota, and Canada: riverine sandbars; reservoir shorelines; and prairie wetlands. Watersurface areas of these habitats fluctuate in response to wet–dry periods; decreasing water surface areas exposeshorelines that plovers utilize for nesting. Climate varies across the region so when other habitats are unavailable forplover nesting because of flooding,...

Wildfire is ubiquitous to interior Alaska and is the primary large-scale disturbance regime affecting thawing permafrost and ecosystem processes in boreal forests. Since surface and near surface hydrology is strongly affected by permafrost occurrence, and wildfire can consume insulating organic layers that partially control the thickness of the active layer overlying permafrost, changes in the active layer thickness following fire may mark a distinct change in surface hydrology. In this study, we examined surface area dynamics of lakes following wildfire in four regions of Interior Alaska during a 25-year period from 1984 - 2009. We compared the surface water dynamics of lakes in burned areas relative to lakes in...

Annual export of major and trace solutes are determined for the Yukon River based on summing 42 tributary contributions. First we show that annual discharge of the Yukon River can be computed by summing calculated annual discharges from 42 tributaries using a previously published regional regression equation. Next, annual loads for 11 solutes are determined by combining annual discharge with point measurements of solute concentrations in tributary river water. Based on the sum of tributary contributions we find that the Yukon River discharges approximately 211 km super(3) yr super(-1) of water and 33 million metric tons of dissolved solids each year at Pilot Station, AK. Disch arged solutes are dominated by cations...
