541-822-6336 mark.schulze@oregonstate.edu Other Researcher 2019-08-28 Collection and analyses of precipitation chemistry were initiated in 1969 at the low-elevation Primary Met site, and in 1973 at a mid-elevation Hi-15 site. Rain collection samples accumulate from one week to three weeks in bulk and NADP type collectors and then are transported to Cooperative Chemical Analytical Laboratory (CCAL) for analysis. Analytes include nitrogen, phosphorus, carbon, and cations and anions as well as pH, conductivity, alkalinity and particulate sediment. Concentration and volume of precipitation are combined for inflow. Dry deposition chemistry concentrations began in 1989 and are analyzed 2-4 times per year at one site. The original objectives were to evaluate precipitation chemistry inputs versus chemistry outputs in streamflow from forested watersheds. The study has evolved into a general monitoring effort for precipitation chemistry that is among the least contaminated of any within the USA.

Sample sites are the H. J. Andrews Administrative site (PRIMET) and Watershed 7. The precipitation collector at the administrative site (RCADMN) represents nutrient input for Andrews Watersheds 2, 9, and 10. The original Hi-15 precipitation collector (RCHI15) and the current NADP-like collector (RCHIR7, RCHID7) represent nutrient input for the Andrews Hi-15 Watersheds 6, 7 and 8. -122.25588900 -122.17674400 44.26663600 44.21184400 430 999 meter 1968-10-01 2019-05-22 The study examines precipitation chemistry and solute budgets in small watersheds. The original objective was to evaluate the magnitude of nutrient inputs and outputs after timber harvest, but is now an established general monitoring effort for precipitation chemistry.

An update history is logged and maintained with each new version of every dataset.

annually Original metadata creation. Version1 1984-10-09 All data was automated in the fall of 1979. Regular updates are made annually, but are occasionally delayed based on the availability of precipitation values. Precipitation is combined with nutrient concentration data to produce input in kg per hectares. Originally, precipitation from rain gages at WS09 and WS10 were used to produce input totals, but these gages were discontinued. In 1995, all data was rerun using the Climatic Station @WS2 precipitation record. Analysis codes Q (Questionable lab value) and * (value below detection limit) were initiated in April, 1991. Version2 1995-09-30 Metadata restructured and moved into SQLServer metadata database LTERMETA. Data moved into SQLServer database FSDBDATA. Version3 2002-02-18 This is a major update of this data set. Nutrient concentrations (Entity 1) are updated through mid-2004 (last version was through mid-2001). Entities 2 and 3 were updated through wateryear 2003 (previous version was only through 1997). Precipitation values were updated for RCADMN using CS2MET (note :PRIMET was used after March 2003 but will be replaced later with CS2MET), and precipitation values were updated to RCHIR7 using H15MET. Attributes were renamed in this update process to be unique by attribute definition for the CF002 dataset . Version4 2005-03-17 This is a major structural revision and update of data into winter 2007, lab sets HJAN226-HJAN275, lab numbers 3324-4093. Unfiltered total nitrogen (UTN) and total dissolved nitrogen (TDN) are added with flags. UTN and TDN are calculated and coded as 'D' - derived before May 2005. Particulate P, Particulate N, dissolved organic nitrogen (DON), and anion-cation ratio are calculated from other analyses for all records in Entity 1 and flagged as 'D'erived. Dissolved organic Phosphorus calculation was dropped from Entity 2. UTKN and TKN are changed to 2 decimals for all values. Precipitation is changed to 2 decimals. Enddate and endtime are changed to truetype date_time. Other attributes are renamed, ie., TDP (was TP), PO4P (was OP). Silica samples are flagged as 'Q'uestionable before 10 March 1983 - Samples were frozen and analyses inconsistent. Version7 2007-10-03 Additional corrections and improvements in methods metadata. Correction of analytical codes for 1970-1971 for TKN, DON, and TDN, with correction of an annual 1971 DON concentration. Version8 2007-10-16 Entity 1 is updated into March 2010 although streamflow is only available through Sep 30 2009 (WY 2009), and USGS Lookout Creek streamflow for GSLOOK site through WY2008. 'Y' values are removed from Entity 1 and the streamflow (or precip) and the streamflow (or precip) qualifier codes for the beginning wateryear sample are corrected. A local copy of Entity 1 with the Y values will be maintained to produce annual flux and concentration summaries. Attribute 'wateryear' has been added to Entity 1 and Entity 2. Entity 2 has been updated through WY 2009 for all streamflow and precip sites except GSLOOK (through WY 2008). This is the first Entity 2 update including GSLOOK, WY 2005 (partial year) and complete WY 2006-2008. Resolution of 'S' and 'C' issue: There are 5 instances in which streamflow samples were collected and saved and analyzed in combination with the next sample. To satisfy Sherri's need to see even 3-week calculated values, flux values are present for the sample type = 'S' and represent the concentrations over the 6-week interval, but use the streamflow total for period ending at the Saved sample collection. Flux values for the sample type 'C' use the 6-week concentrations and streamflow beginning from the time of the saved sample collection. In the CP002 precip data, the 'S' samples are removed from Entity 2 and the 'C' type samples include precipitation over the entire collection period of any saved samples. Resolution of 1989-1991 issues of independent weekly partial and grab samples: Again, the issue here is that comparable 3-week sample intervals are desired. In the spreadsheet list sent by Linda Ashkenas several 3-week intervals with additional weekly samples were identified for WS 9 and WS10. New values are calculated at even 3 week intervals. For these cases, Entity 2 values have been modified proportionally based on the weekly collections and the formal rules developed after 1991 used to combine weekly samples in the lab. That is, partial samples were used to represent the total streamflow for the complete intended interval. Grab samples were not used in the calculations. If a 3 week interval included a partial or grab sample type, the 3-week interval was labeled as 'P' partial. In all cases the 3-week flux value represents the streamflow for the entire 3-week interval even if the concentrations are based on 'P' partial samples. This was also applied to 2 similar intervals in Feb 1996 (WS9)and Dec 1997 (WS9 and 10). However, the 1996 flood interval for WS 10, Feb 1996, could not be combined with certainty using this mathematical approach and was left as is. Note that Entity 2 before and including WY 1998 data is no longer reproducible by my automated program. Another issue arose where some concentration values were qualified with a 'C' (beginning WY 2007). 'C' values are defined as 'value confirmed, contamination or experimental tracer suspected'. In these cases the values were rerun (double-checked) by the lab confirming lab results. In all cases, field notes indicated a worm or other large insect had contaminated the sample. In two cases conductivity and chloride values were very high and an experimental tracer is suspected. Currently, these values are left in Entity 1, and also are left in entity 2 with the 'C' qualifier. However, these values were removed for calculation of mean annual concentrations. While the mean annual concentrations generally change very little by inclusion of this point, there is one case in which the annual ammonia value changed dramatically. Version9 2010-06-28 Updated attribute description for attributes with a fine resolution datetime measurement scale to include 'PST' (pacific standard time). Version12 2012-08-30 Entity 1 is updated from 8 March 2010 to 2 July 2014. Precipitation values are added and precipitation is updated beginning WY 2006 for RCHIR7 rain collector. alkalinity is converted to CaCO3 (from HCO3-C) Version14 2014-09-10 Entity 2 is now updated through 2 July 2014 and Entity 3 through WY 2013. Precipitation from CENMET station is now used for all Hi-15 collectors beginning WY 2006. Alkalinity has been converted to units of calcium carbonate (CaCO3) from bi-carbonate (HCO3-C). The NADP-style collector has been discontinued due to problenatic operation after WY 2013 (RCHIR7 and RCHID7). A new bulk type collector begins operation for WY 2014 (RCHIF7). Version15 2014-09-12 Entity 6 is created from precipitation water chemistry sample field log sheets that include sample collection times, sampler type, and field and lab comments associated with the water sample collection and laboratory analyses. Version16 2015-08-14 Entity 6 is updated from June 2015 through October 2015. Version17 2015-12-04 Critical update to fix rendering of custom units and correct for illegal characters in entity 6 field_comments. Version18 2016-08-25 All entities are updated from July 2014 into May 2016. Codes for all analytes are revised so that blank codes (good values) are changed to 'A' (Accepted values). Version19 2016-10-31 All Entities are updated from May 2016 until May 2019. Precipitation values are taken from PRIMET (RCADMN) and CENMET (RCHIF7) Version20 2019-08-28 Information Manager

(541) 737-8480 lterweb@fsl.orst.edu http://andrewsforest.oregonstate.edu/ Field Methods - CP002 Precipitation chemistry is sampled at a low elevation site (RCADMN at Primet, 430m) and a mid-elevation site (RCHIR7 in WS 7, 999m). Samples are stored in polyethylene containers until analysis. Prior to 1988, samples from both sites were collected every 3 weeks and transported to the Corvallis lab (CCAL) for analysis. Beginning October, 1988, samples are collected weekly and refrigerated at the Andrews. Precipitation samples are transported to Corvallis every 3-weeks, and weekly samples are analyzed individually. Beginning April 22, 2008, weekly samples are combined into a single composite sample and analyzed every 3 weeks similarly to the streamflow chemistry samples (CF002). Due to limited resources, winter-time, cold-weather samples (Nov-Mar) are only collected every 3 weeks, however, from April-Oct samples are still collected weekly and refrigerated. Originally, collectors at both sites were open orifice (Polyethylene carboy jug with funnel). At the H. J. Andrews administrative low elevation site (RCADMN), precipitation was collected at the top of a 55 ft tower located in a clearcut. Water was stored in a polyethylene container inside an insulated shelter at the tower base. On January 20, 1982, the collector was moved to a 5 ft platform within 10 meters of the original location, and the polyethylene container is stored in an uninsulated bucket on the platform. At the mid-elevation site (RCHI15) precipitation was collected at the top of a 10 ft pole located in a clearcut near the top of Watershed #6. Water was stored in a polyethylene container inside an insulated shelter at the base of the pole. In October, 1988, a new collection site (RCHIR7) was started in a shelterwood with subsequent overstory removal near the top of Watershed # 7. An NADP-type wet/dry deposition sampler mounted on top of a 5 ft tower was used instead of the open orifice samplers used at the original site. The water is stored in polyethylene containers inside an uninsulated housing on top of the sampler. The "dry" side (RCHID7) container is collected and analyzed 2-4 times per year. The replacement collector (RCHIR7) and the original collector (RCHI15) at these mid-elevation sites were collected and analyzed concurrently for 9 weeks before the old site was discontinued. Total precipitation from the Climatic Station WS#2 (CS2MET) by collection period was used in conjunction with nutrient analyses from the low elevation rain collector (RCADMN) to determine nutrient influx until 10/01/2002. Beginning with WY 2003 (10/01/2002), total precipitation from the Primary Meteorological Station (PRIMET) is used in conjunction with RCADMN. Total precipitation from the Hi-15 Meteorological Station (H15MET) by collection period is used in conjunction with nutrient analyses from the mid elevation rain collectors, originally RCHI15 and currently RCHIR7, to determine nutrient influx. Beginning with WY 2014 (1 Oct 2013), the NADP-style collector was dismantled and removed due to problematic operation. Dry deposition samples at this site were discontinued. Precipitation collection continues with an open orifice style collector (RCHIF7), which is located where the RCHIR7 NADP-style collector had been. Assigning sample type codes (TYPE) is described here. Beginning Oct 1988, samples are collected weekly for analysis, and all samples are assigned sample type codes. A sample that is the result of precipitation collected continuously over the entire weekly period is considered a complete or full sample (TYPE="F"). Operational or other problems causing an incomplete or partial sample over the weekly period are coded as partial (TYPE="P"). Examples might include the malfunction of the sample lid on the NADP collector or possibly a collector overflow. Should zero precipitation result in no sample being collected for any week, sample type is no sample (TYPE='N'). Beginning 2007, there has been infrequent use of a sample type 'Biased' (TYPE='B'), which represents a wet collector sample that has had dry deposition input due to a faulty lid that is stuck open. Beginning April 22, 2008, samples are only analyzed every 3 weeks. If any of the weekly samples are partial or missing, the 3-week composite sample will be labeled sample type partial (TYPE='P'). Before Dec 1988, samples were collected on a 3-week basis. Successful operation of the collector over the 3 week period represents a complete or full (TYPE="F") sample. When the collector failed or was out of operation for any part of the 3 week period, the sample is designated as partial (TYPE="P"). When samples contained insufficient water for analysis, they were saved (TYPE='S') and combined (TYPE="C") with the following sample for analysis. Multiple samples might be saved and combined. In these cases the concentration data (Entity 1) and the flux data (entity 2) show precipitation for this entire period, and the "C"ombined sample's analytical measurements represent the entire period over which samples were saved. Date and times listed as data_time in the data files refer to the end date of a collection period. Data is summarized by water year: October 1 to September 30. To allow summarization by water year, an artificial end-of-year sample point (TYPE="YE") is inserted on Sept 30 every year (Entity 2 flux data only) but is not an actual sample . Nutrient concentrations from the next analyzed sample (in October) are used with the precipitation total ending Sep 30 , the end of the wateryear, to calculate flux for this interval, which is designated TYPE="YE". Similarly, the flux value for this first sample of the new wateryear in October is calculated based on concentration values from the first October sample and on precipitation beginning Oct 1. Andrews-designed collector (RCADMN, RCHI15, RCHIF7): An open orifice (polyethylene jug with funnel) located on a tower. Aerochem Metrics Model 301 NADP-type wet/dry deposition sampler (RCHIR7/RCHID7): The orifice of this collector is only open during precipitation events. It is controlled by a heated grid sensor which moves a cover from the "wet" side to the "dry"side when precipitation covers the grid of the sensor. The cover moves back to the "wet" side as the water is evaporated off the sensor grid by the heating element. The collector is modified for cold, snowy climates with an electric heater blanket and heat light to prevent freezing of the motor box and the lid arms and a v-shaped structure to prevent snow build-up. Laboratory Methods - CP002 Laboratory procedures: Official compilation of water analyses begins with the WY 1969 (10/1/1968). Originally, samples are analyzed for suspended sediment, alkalinity, pH, ammonia nitrogen, nitrate, nitrite, dissolved kjeldahl nitrogen, ortho (reactive soluble) and total dissolved phosphorus, sodium, potassium, calcium, magnesium, and silica. Sulfate was determined for WY 1972 and sulfate and chloride in WY 1979. Sulphur and Chloride were analyzed at the University of Washington beginning 1988 until 2004, and are now conducted by CCAL at Oregon State. Analysis of specific conductivity was added in Dec 1974 and total P on an unfiltered samples in Oct 1974. Analysis of total kjeldahl N on an unfiltered sample was started in June 1978. Total N is calculated from the total Kjeldahl and NO3-N until May 2005. Direct analytical measurement of Total dissolved N and Total N (unfiltered sample) begins in May 2005. Dissolved organic carbon analytical measurement begins in 2003. Aluminum, iron, manganese, and nitrite were below levels of detection and were subsequently dropped from analysis. In general, duplicates were run on all analyses until Oct 1983, and are currently conducted randomly. Other notes on analyses: 1) Since dry deposition analyses were initiated in 1989, 250 ml of dionized water are added to the dry deposition samples before analyses. 2) From 1969 - 1973 samples were analyzed for free ammonia (FNH3) prior to being digested for total nitrogen (DON). The FNH3 was driven off and collected and analyzed separately. Then the sample was digested and analyzed for DON. For these years TKN represents the sum of DON and FNH3. Listed Total Kjeldahl N (TKN) values from 6/1/1970-6/21/1971 for RCADMN do not include free ammonia (NH3-N) and are shown as estimated. 3) A combination of factors cause the results for silica prior to 17 March 1983 to be labeled as "Q"uestionable. Historic records indicate that many, if not all, of the samples prior to that date were frozen prior to analysis for silica. Freezing samples prior to analysis for silica will reduce the final analyzed concentration of reactive silica (the form we have historically determined). Another complicating factor is that the methodology changed about this same time. Until 1982, a stannous chloride method was used to determine silica, and this method is more prone to variability due to reagent instability. Until May 2005, the CCAL lab analyzed for total dissolved Kjeldahl nitrogen (TKN) and also for total Kjeldahl nitrogen (UTKN), which is performed using an unfiltered sample and includes any particulates (sediment, biota) present. All dissolved results exclude particulates of 0.7 microns or greater. TKN includes NH3-N, but does not include NO3-N. The following are mathematically calculated in the data set and coded as 'D' when this occurs: Dissolved organic nitrogen (DON) = TKN - NH3N Total dissolved nitrogen (TDN) = TKN + NO3N (directly analyzed after May 2005) Total nitrogen (UTN) = UTKN + NO3N (directly analyzed after May 2005) Particulate nitrogen (PARTN) = UTKN-TKN, or UTN-TDN (after May 2005) Particulate phosphorous (PARTP) = UTP - TDP Currently, all samples are filtered upon arrival at the Corvallis lab (CCAL) and pH, alkalinity, conductivity, and autoanalyzer runs (NO3-N, NH4-N, SI) are made immediately. All analyses are completed within 6 weeks. Generally, samples are stored at 0 degrees C if not analyzed immediately. In the first year of sample collection (1968-1969), water was stored at 0 degrees C until operation of the PNW-1653 local lab in spring, 1969. Generally, there is much greater trust and consistency to analytical measurements beginning in 1983. Processing Procedure - CP002 A Visual Foxpro program (pio_true) combines nutrient concentration data with precipitation to produce outputs in kilogram per hectare by water year (Entity 2), and creates annual nutrient concentrations (Entity 3). This program replaces the original PIO99 Fortran program in March 2005. Precipitation values are obtained from both CS2MET (before WY2003) and PRIMET (beginning WY 2003) for the RCADMN rain collector. Precipitation values are obtained from both H15MET (before WY2006) and CENMET (beginning WY 2006) for the Hi-15 rain collectors (RCHI15, RCHIR7, and RCHIF7).

The laboratory has automated the method used for analysis of total phosphorus (total phosphorus for unfiltered samples and total dissolved phosphorus for filtered samples) as of 16 June 2010. Samples submitted to the laboratory will now be analyzed using the Technicon Auto-Analyzer II (the same instrument used for analysis of nitrate, ammonia, phosphate, silica and total nitrogen). We have discontinued the routine use of the manual method using the Milton-Roy 601 spectrophotometer at this time. We ran the manual method through the end of calendar year 2010 in an attempt to run comparisons for projects with historic results from the manual method. Results indicate there is expectation for reduced UTP/TDP due to the analytical change.

Watersheds 1, 2, 3: Though Watersheds 1, 2, and 3 are similar in terms of climate, geology, soils, and topography, they differ in average annual water yield. During the pre-harvest period 1953-1962, Watersheds 1 and 3 produced 86% and 88%, respectively, of the annual average streamflow produced by Watershed 2 (Rothacher et al 1967). From 1964 to 1992, Watershed 2 annual streamflow yield averaged 126 cm and ranged from 37 to 214 cm. Annual runoff: precipitation ratios averaged 0.56 and ranged from 0.28 to 0.71. Monthly runoff volumes follow closely the seasonal pattern of precipitation. Largest runoff volumes occur in December and January, and smallest in August and September. Typically, the largest peak flows occur during rain-on-snow events in which latent heat transfers melt shallow warm snowpacks, increasing water input to the soil by up to 25% (Harr 1981). Maximum rates of runoff during these events may exceed 80 percent of the average rate of precipitation for the preceding 12 to 24 hours (Rothacher et al 1967). Watersheds 9 and 10: Prior to logging, vegetation on both watersheds consisted primarily of 450-year-old Douglas-fir mixed with hemlock and younger Douglas-fir. WS 9 left undisturbed as the control, 21 ac. WS 10 logged by skyline system to single landing, spring, summer 1975. WS 10 unburned, 25 acres. The Hi-15 Rain Collector represents nutrients inputs in conjunction with streamflow outputs for WS 6, 7, and 8 and is positioned on WS 7. Watersheds 6, 7, and 8: The high-elevation watersheds also show differences in annual water yield. During the pre-harvest period 1964-1974, Watersheds 6 and 7 produced 113% and 79%, respectively, of the annual average streamflow produced by Watershed 8 (Harr et al 1982). From 1964 to 1992, Watershed 8 annual streamflow yield averaged 122 cm and ranged from 43 to 218 cm. Annual runoff: ppt ratios averaged 0.56 and ranged from 0.34 to 0.76. Monthly runoff volumes in the high-elevation watersheds follow the same pattern as observed in the lower-elevation watersheds. Snowpack in the high-elevation watersheds tends to be deeper, colder, and more persistant than in the lower watersheds. Contribution of snowmelt to streamflow may continue through June. Sampling frequency: 1-3 weeks Precipitation samples from two rain collectors and one dry deposition collector are analyzed for nutrient concentrations and fluxes calculated using amount of precipitation inputs during that period. The rain collector at the low elevation administrative site (RCADMN) was established in 1968 in conjunction with stream water chemistry measurements at Andrews WS 9 (control) and WS 10 (clearcut), and also used in conjunction with WS1 (clearcut) and WS2 (control). The rain and dry deposition collectors at the Hi-15 mid-elevation site (positioned mid-slope WS 7) are paired with the HI-15 small watershed study including streamflow nutrient concentration and outflows on WS 8 (control), WS 6 (clearcut), and WS7 (shelterwood cut). Dry deposition samples were discontinued after after WY 2013. The original HI-15 rain collector (RCHI15) was established mid-slope WS 6 in 1969 and replaced with an NADP-style collector in 1988, which separates precipitation collection (RCHIR7) and dry deposition collection (RCHID7). Beginning 1 October 2013 the NADP-style collector was removed and a bulk collection sample initiated (RCHIF7) at the same site in the Hi-15.

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 CP00201 Precipitation water sample nutrient concentrations: Precipitation samples are collected and analyzed on a 3-week basis for nutrient concentrations.
