Priority-Pollutant Trace Elements in Streambed Sediments of the Cook Inlet Basin, Alaska, 1998-2000 This report describes the analysis of priority-pollutant trace element concentrations in streambed sediment samples collected in the Cook Inlet Basin during 1998 and 2000. Categories: Publication; Types: Citation; Tags: M2-Standardized Stream and Lake Information
Identification of linear and threshold responses in streams along a gradient of urbanization in Anchorage, Alaska We examined biotic and physiochemical responses in urbanized Anchorage, Alaska, to the percent of impervious area within stream basins, as determined by high-resolution IKONOS satellite imagery and aerial photography. Eighteen of the 86 variables examined, including riparian and instream habitat, macroinvertebrate communities, and water/sediment chemistry, were significantly correlated with percent impervious area. Variables related to channel condition, instream substrate, water chemistry, and residential and transportation right-of-way land uses were identified by principal components analysis as significant factors separating site groups. Detrended canonical correspondence analysis indicated that the macroinvertebrate... Categories: Publication; Types: Citation; Tags: M2-Standardized Stream and Lake Information

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
