In the Fall of 2010 there were eleven collection periods and in the Spring of 2011 there were eight collection periods. Data is no longer being collected. Throughfall and rainfall were measured at point locations, measured for the quantity and isotopic composition (Oxygen-16/18 and Hydrogen/Deuterium). Stemflow was also collected off of two PSME trees, one on the north-facing and one on the south-facing slope. These are the "plots" for this study, although they have no defined radius. During the Fall 2010 collection period, thirteen collectors were used, near the stream channel, along the trail in WS1. During the Spring 2011, there were eighteen collectors at each of two plots. Rainfall was also measured in an opening at the WS1 landing for comparison. interception throughfall water balance evaporation LTER controlled vocabulary Data and financial support were provided by the HJ Andrews Experimental Forest research program, funded by the National Science Foundations Long-Term Ecological Research Program (DEB 08-23380)Related PublicationsAllen, Scott T. 2012.

Additionally we were interested in patterns of throughfall isotopic composition and depth. Better understanding of throughfall patterns in heterogeneous terrain is important because since both rainfall and vegetation patterns are highly variable in complex terrain, and summer interception loss could be an important control over the spatial variability of the availability of moisture, coinciding with when vegetation is most water-limited.

These were a long tube with a 7390 sq. mm collection area. In the spring, Throughfall was collected using gages we constrcuted from standard polyethylene 2l and 4l jugs. A 4 liter jug had the bottom cut off, used as a funnel. This funnel connected to a 2l bottle used as a the colletion bottle. They were connected by two caps attached with eight 1/8" holes drilled through. Two plots located on WS1 with indefinite boundaries. For the fall, collection of throughfall was on a haphazardly placed collectors along the WS1 trail, with collectors 8-13 being located south of the stream, along the first switchback ascending the north-aspect slope. Collectors 1-7 were located along the trail, on the section north of the stream, paralleling the stream. All collectors were under Douglas-fir trees. During the spring collection period, a different sampling regime was used. Plots were located on both the north and south aspect slopes (coordinates are listed in metadata). Within each of the plots there were 36 potential collection locations. Of these 36 locations, 18 were randomly selection and sampled for each collection period. Therefore, collector number refers to a collection location that is permanent, rather than a specific collector used. Sampling frequency: irregularly, dependent on precipitation events Two trees were selected for rainfall/throughfall analysis, one on the north slope and one on the south slope. A control was also constructed in a corresponding open area. During the first year of collection, the sampling was sporadic and samplers randomly placed. During the second year of collection, samplers were placed in coordinated locations under douglas fir trees of similar sizes and 18 of 36 collectors were randomly collected, and their water isotopic compositions analyzed.

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. Data were provided by the HJ Andrews Experimental Forest research program, funded by the National Science Foundation's Long-Term Ecological Research Program (DEB 2025755), US Forest Service Pacific Northwest Research Station, and Oregon State University. National Science Foundation: DEB1440409 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. 1 MV00301 Throughfall amount and isotopic composition on Watershed 1: MV00301.csv 51835 0936ead7a9e1920ce32b33eb36b104d9 1 \r\n column , " http://andlter.forestry.oregonstate.edu/ltermeta/ltersearch/dataaccess.aspx?docid=MV00301_v1.csv 2010-10-01 2011-07-31 DBCODE Database Code (assigned by FSDB data manager) char(5) MV003 FSDB Database code MV003 ENTITY Entity number (data table number) numeric(2,0) number 1 natural 1.0000 1.0000 YEAR Year of measurement numeric(4,0) number PERIOD Site code char(4) FALL Fall sampling period from 2010 SPNG Spring of 2011 collection period START_DATETIME date and time of deployment datetime YYYY-MM-DD hh:mm:ss 10/9/2010 9:30:00 AM 6/19/2011 7:00:00 PM END_DATETIME date and of collectoin datetime YYYY-MM-DD hh:mm:ss 10/10/2010 5:30:00 PM 7/1/2011 11:00:00 AM TYPE Throughfall, rainfall, or stemflow char(2) TF Throughfall SF Stemflow RF Rainfal COLNUM collector number (refers to a consistent point location) numeric(2,0) number 1 natural 1.0000 36.0000 PLOT plot char(10) WS01_SA_L WS1 Throughfall Collection, Landing of WS1 WS01_SA_S WS1 Throughfall Collection, South side (north-aspect) plot WS01_SA_N WS1 Throughfall Collection, North side (south-aspect) plot WS01_SA_F WS1 Throughfall Collection, Fall sampling Plot COLLECTORSIZE diameter of collector used char(3) 93 93 millimeter diameter collector 97 97 millimeter diameter collector 155 155 millimeter diameter collector NA No collector used VOL Volume measured in the collector numeric(5,0) milliliters 5.000000 real 0.0000 11000.0000 DEPTH Throughfall/rainfall depth (vol / collector's area) numeric(5,2) millimeters 1 real 0.0000 300.0000 DEL18O Oxygen-18 as compared to the Vienna Standard Mean Ocean Water (VSMOW) numeric(6,2) permil 0.070000 real -16.0000 -5.0000 DEL2H Deuterium (heavy hydrogen) as compared to the Vienna Standard Mean Ocean Water (VSMOW) numeric(7,2) permil 0.280000 real -200.0000 -30.0000 PRIMARY MV00301.COLNUM MV00301.START_DATETIME MV00301.PLOT MV00301.TYPE NOTNULL MV00301.COLNUM MV00301.END_DATETIME MV00301.START_DATETIME MV00301.DBCODE MV00301.ENTITY MV00301.PERIOD MV00301.PLOT MV00301.TYPE MV00301.YEAR 500 parts per thousand, relative to a standard. for isotopes.
