Yukon River Basin Studies Products/BibliographyThe U.S. Geological Survey (USGS), Water Resources Discipline, National Research Program (NRP) and the USGS Alaska Science Center have been cooperating to collect baseline and process-based water quality data in the Yukon River Basin (2001-2005) as part research-based National Stream-Quality Accounting Network (NASQAN) study to understand the Basin’s response to climate change. A better understanding of baseline trends and processes controlling the water quality of the Yukon River and its tributaries will facilitate the proper management of resources as conditions change in response to environmental change. The NASQAN Yukon River study began with the first sample collection in October 2000 at five fixed monitoring stations (three on the mainstem Yukon River and two major tributaries). Each year following, each fixed station was sampled seven times (once under ice and six open water) to build a multi-year water-quality baseline dataset. During 2002-2005, process-based studies (synoptics) were conducted, sampling the entire 2,100 mile reach of the Yukon River from headwaters in the Yukon Territory, Canada, to Pilot Station, Alaska, near the outlet to the Bering Sea. In addition, 47 major tributaries also were sampled. The last Fixed Station sample was collected in September, 2005. Each sampling consisted of a complete suite of water quality samples measuring over 90 constituents. The following is the most recent list of products delivered or approved that disseminate information, whether it be description of activities or logistics, baseline data, preliminary findings, interpretation of processed-based data, or outreach.
