# Stream chemistry concentrations and fluxes using proportional sampling in the Andrews Experimental Forest, 1968 to present ## Dataset - **Database Code:** CF002 - **Title:** Stream chemistry concentrations and fluxes using proportional sampling in the Andrews Experimental Forest, 1968 to present - **Abstract:** Stream chemistry sampling and analysis was initiated at the H.J. Andrews Experimental Forest in 1968 in two small watersheds (Watersheds 9,10). Sampling has expanded as additional paired watershed studies (Watersheds 1, 2, 6, 7, 8) and monitoring (Mack, Lookout Cr) were initiated over time. Water samples are collected proportionally to streamflow as a function of stage height and composited at each stream gauging site. Composite sample periods are generally three weeks and 3 one-week samples are commonly composited in the lab before analysis. Water samples are analyzed at the Cooperative Chemical Analytical Lab (CCAL) (http://www.ccal.oregonstate.edu/ ). Concentrations of analytes include dissolved and particulate nitrogen, phosphorus, carbon, as well as pH, conductivity, suspended sediment, and full suite of cations and anions. Annual mean concentrations are calculated by weighting 3-week periods by streamflow. Fluxes are calculated using concentrations and flow. Monthly concentrations and fluxes were interpolated from the 3-week sampling data. The original objective was to examine the nutrient budgets for small watersheds and to evaluate changes in average concentrations and fluxes following timber harvest in comparison with unharvested reference watersheds. This study is conducted in conjunction with Andrew's precipitation chemistry (CP002) and the U.S. National Atmospheric Deposition Program (NADP). - **Keywords:** hydrology; water chemistry; suspended solids; discharge; streamflow; timber harvest; inorganic nutrients; nutrients; dissolved nutrients; water; Long-Term Ecological Research (LTER); inorganic nutrients - **Temporal coverage:** 1968-10-02 to 2024-10-01 - **Principal Investigator:** Sherri L.
