ABSTRACT:
Stream chemistry sampling and analysis was initiated in both of these legacy studies at the Coyote Creek and Fox Creek watersheds in 1969 and concluded in 1981. Water samples were collected proportionally to stream discharge as a function of stage height and composited at each stream gauging site. Composite sampling periods were generally three weeks. Water samples were analyzed at what is now called the Cooperative Chemical Analytical Lab (CCAL) at Oregon State University. Concentrations of analytes include dissolved and particulate nitrogen and phosphorus, pH, conductivity, suspended sediment, and a full suite of cations and anions. Fluxes are calculated using concentrations and flow. This work was funded by the U.S. Forest Service Pacific Northwest Research Station.

ENTITY TITLES:
1Proportional stream water sample nutrient concentrations (Oct 6 1969 - Oct 1 1982)METADATADATA
This entity is the raw proportional sample concentration data collected periodically (usually every three weeks).
2Stream water nutrient outflow (kg/ha) for each proportional sampling interval (Oct 6 1969 - Oct 1 1982)METADATADATA
These data are calculated fluxes for each proportional sample
3Stream water nutrient mean annual concentrations (Oct 1 1969 - Oct 1 1982)METADATADATA
