Abstract
This study examines headwater stream nutrients at stream gaging sites during selected storms in the Andrews Experimental Forest. High frequency storm sampling was conducted to examine flow path dynamics, basin characteristics, seasonal trends, and differing responses and mobility among analytes on streamwater nutrient concentrations and fluxes.

Abstract
- The H.J. Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics.
- Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition.
- The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources.

Study Area Description
-
Long-Term Ecological Research The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms.

Study Description
This study examines headwater stream nutrients at stream gaging sites during selected storms in the Andrews Experimental Forest. High frequency storm sampling was conducted to examine flow path dynamics, basin characteristics, seasonal trends, and differing responses and mobility among analytes on streamwater nutrient concentrations and fluxes. Evaluating spatial and temporal variability of stream nutrient concentrations at headwater gaged basins during storms in Andrews Experimental Forest Field Methods - CF006
Purpose: Evaluating spatial and temporal variability of stream nutrient concentrations at headwater gaged basins during storms in Andrews Experimental Forest
Methods
Method Steps
Field Methods - CF006
- Sigma samplers were installed in gage houses. Tygon tubing was run from samplers to stream. Samplers were manually turned on at beginning of storm and programmed to collect stream water samples every 2-4 hours.
Laboratory Methods - CP006
- Samples were refrigerated after being collected from gage house. They were filtered in the laboratory within 24 hrs using ashed GFF filters. Samples were then frozen. For chemical analysis, see Cooperative Chemical Analytical Lab web page http://ccal.oregonstate.edu/
Quality Assurance - CF006
- See CCAL web for QAQC http://ccal.oregonstate.edu/
