Folder: Water-Quality Data from the Yukon River Basin in Alaska and Canada ( Show all descendants )5 results (7ms)
This dataset includes data quality assurance information concerning the Relative Percent Difference (RPD) of laboratory duplicates. No laboratory duplicate information exists for 2010. The formula for calculating relative percent difference is: ABS(2*[(A-B)/(A+B)]). An RPD of less the 10% is considered acceptable.
This dataset contains replicate samples collected in the field by community technicians. No field replicates were collected in 2012. Replicate constituents with differences less than 10 percent are considered acceptable.
This dataset includes laboratory instrument detection limit data associated with laboratory instruments used in the analysis of surface water samples collected as part of the USGS - Yukon River Inter-Tribal Watershed Council collaborative water quality monitoring project.
This dataset contains data collected from field blanks. Field blanks are deionized water processed in the field by community technicians using processing methods identical to those for surface water samples. Field blanks are then analyzed in the laboratory following procedures identical to those for surface water samples.
The dataset includes field measurements and laboratory analysis of water-quality data collected by trained community technicians across the Yukon River Basin in Alaska and Canada and Yukon River Inter-Tribal Watershed Council staff and analyzed at the U.S. Geological Survey National Research Program laboratories in Boulder, CO.
