Summary
Abstract:
Water quality monitoring is conducted at 26 National Estuarine Research Reserves (NERR) at four locations within or adjacent to the reserve. The following parameters are collected at least every 30 minutes: water temperature, specific conductivity, salinity, percent saturation, dissolved oxygen concentration, water depth, pH and turbidity. All water quality data loggers will be deployed from a known depth from the bottom at each site.
Purpose:
Research objectives Measurements are taken every 30 minutes over a three to four week period at four sites in Elkhorn Slough. One site South Marsh (SM) is in a relatively unimpacted side channel of the slough and the second, Azevedo Pond (AP) is in a pond that receives fertilizer and pesticide runoff from an adjoining strawberry field. The third site, North Marsh (NM), was added in April 1999 and ... is located in an area where there is both agricultural and non-agricultural runoff. The fourth site Vierra Mouth, added March 14, 2001, is located at the mouth of the slough and is used to identify oceanic influence. The purpose of this research is to identify the base parameters for Elkhorn Slough by using South Marsh as the control site and the other three sites are impacted sites and monitored for possible future problems.
SUPPLEMENTAL INFORMATION:
Associated researchers and projects Elkhorn Slough National Estuarine Research Reserve and the Elkhorn Slough Foundation have had an ongoing program to monitor estuarine water quality in the central Monterey Bay region since 1988. Currently, 24 stations are monitored monthly for temperature, salinity, dissolved oxygen, pH, turbidity, nitrate, ammonium and dissolved inorganic phosphate concentrations. Two of these stations on the Reserve are about 400 m from the SM site. Data collection began at these two stations in September 1989. A monthly monitoring station is also located at Azevedo Pond within 10 m of the YSI deployment. Monthly data from the Azevedo Pond are available from March 1992. The University of California Santa Cruz Agro Ecology Program has an ongoing project to examine the effects of agricultural production on an adjacent wetland. Matthew Werner, Marc Los Huertos, Felecia Rein, Sean Swezey, Mark Silberstein, Andrew De Vogelaere, Ron Tjeerdema have been the principal investigators. There are many projects associated with Elkhorn Slough. Please contact this NERR site for a list of ongoing research projects. II. Physical Structure Descriptors Other remarks/notes A) There were a few instances at this NERR site where turbidity recorded small negative values (-0001 and -0002). Because turbidity has a range of accuracy of +/-2 NTU, the technician did not edit or deleted these values in any way. B) December was a very wet month in this area and during this month. A total of 160 mm of rain fell for the month. This had significant effects on water quality our sites especially salinity and turbidity.

SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character Elkhorn Slough is located on the West Coast of the United States in Central California. It connects with the Pacific Ocean in central Monterey Bay near Moss Landing, California. There are three sampling sites. SM (South Marsh) is in a side channel of the slough and is relatively unimpacted by anthropogenic influences. The YSI is located on the side of a bank in one of the secondary slough channels. AP (Azevedo Pond) (36º 50' 44.64"N, 121º 45' 13.24" W) is in a pond that receives fertilizer and pesticide runoff from a strawberry field in year-round production. The YSI is located about 10m from a culvert connecting the pond to the slough. Tide ranges from 0 to 1.3 meters, salinity ranges from 8.8 during heavy runoff to 41 ppt during strong evaporation, the sonde is located approximately 30 cm off the bottom, the bottom habitat is silty mud. Depth for this site is approximately 1 meter. NM (North Marsh) (36º 50' 4.75" N, 121º 44' 18.33" W) is located in between South Marsh and Azevedo Pond. This site is impacted by both agricultural and urban runoff. With a mean depth of 1 meter, the tidal range is approximately 0.4 meters., salinity ranges between 20 and 40 parts per thousand, there is freshwater runoff from agriculture and upland runoff. The sonde is approximately 30 cm off the bottom and the bottom habitat is silty mud. SM (South Marsh) (36º 49' 05.00"N, 121º 44' 21.83" W) is located approximately 3 km south of NM and is surrounded by mostly reserve land. This site receives runoff mostly from uplands and some from cattle ranches. This site receives the least amount of pollution. The tidal range from 0 to 3 meters, the salinity range is from 22 to 36 parts per thousand and is approximately 30 cm off the bottom. The bottom is slightly compacted silty mud. Depth for this site is approximately 2 meters. The fourth site VM (Vierra Mouth) (36º 48' 39.95" N, 121º 44' 45.40" W) is located at the mouth of the slough and is used to identify oceanic influence. With a mean depth of 2.5 meters, the tidal range is from 0 to 3.2 meters, salinity ranges from 26 to 34 parts per thousand and the sonde is located approximately 30 cm off the bottom. The bottom habitat is compacted mud and sand because there are strong tidal currents. This site receives drainage from the entire watershed since it is at the mouth. There are several auto wreaking yards located approximately 2 km east of this site.

ATTRIBUTE ACCURACY REPORT: Anomalous/Suspect Data January 1-31, 2002 Sampling Period Azevedo Pond Turbidity data are deleted from Jan 12 1530 through the end of the deployment Jan 28 1300 due to a probe malfunction. During the following periods turbidity data were anomalously high or negative, data deleted; Jan 01 1900 Jan 02 1330 Jan 03 0800 Jan 28 2100-2200 Jan 31 1330 Salinity data was suspect ... from Jan 01 0000 through Jan 03 0930 because of probe drift, probably because of mud clogging the probe. Post deployment readings were 48.48 in 53 ms/cm2. Data were not deleted because readings were congruous with the following deployment. There are no pH data Jan 01 0000 – Jan 03 0930 because the probe was not installed on that deployment. North Marsh During the following periods turbidity data were anomalously high or negative; Jan 04 1000 Jan 06 1300 Jan 09 0500 Jan 12 0430 Jan 13 1800 Jan 20 1500 From the beginning of the month to the end of the first deployment 6 NTU was added to the turbidity data because a poor zero calibration caused numerous negative readings. South Marsh All data are deleted from Jan 28 1630 through 2230 and Jan 29 1700 because salinity probe was out of water. Turbidity data are missing from the beginning of the second deployment Jan 14 1200 through the end of the month because probe was not deployed. Turbidity data were deleted from Jan 08 1530 through the end of the first Deployment (01/14 1130) because of increasing probe drift. PH data are suspect from the beginning of the month through the end of the first deployment because of a large jump in data from the end of the first deployment to the beginning of the second deployment (8.11 to 7.88). DO% and DO mg/L data are suspect from the beginning of the second deployment through Jan 27 because of an increase in data then leveling off. Vierra Mouth Turbidity data was deleted Jan 31 1430 because it was an outlier. All turbidity data were deleted from the beginning of the month through the end of the first deployment Jan 07 1200 because no probe was deployed. 4 NTU was added to all turbidity data from Jan 7 1230 through the end of the month because numerous values were negative probably due to a poor calibration in DI. DO% and DO mg/L data were deleted from the beginning of the month through the end of the deployment Jan 07 1200 because data were anomalously high. All pH data are deleted from the beginning of the second deployment (01/07 1230) through the end of the month because of a malfunctioning probe. February 1-29, 2002 Sampling Period Azevedo Pond A significant rain event occurred during feb 16 and 17 where 7 and 22 mm of rain fell. This effect caused low salinity and high turbidity data in Azevedo during these days. + 2 NTU was added to turbidity data from the beginning of the month through the end of the first deployment (Feb 27 1430) because there were numerous negative values due to a poor calibration in DI. + 14 NTU was added to turbidity data from the beginning of the second deployment (Feb 27 1430 through the end of the month) because there were numerous negative values due to a poor calibration in DI. North Marsh The following turbidity data were deleted because they were anomalously high or negative; Feb 1 2230 Feb 2 0730 Feb 3 1830, 0430 Feb 4 1400 Feb 5 0530 Feb 9 1030 Feb 18 1400, 1430 Turbidity data are missing during the second deployment (02/19 1130 through 03/18 1100) because no probe was deployed. The storm event also affected the salinity at this site, causing decreased salinity during low tides. South Marsh Turbidity probe was not deployed for the first deployment thus there are no data from the beginning of the month through Feb 11 1200. Salinity data were deleted from the beginning of the month through the end of the deployment Feb 11 1200 because the probe only read 45.67 in 53 ms/cm. The following turbidity data were deleted because they were anomalously high or negative; Feb 21 1530 Feb 25 1100, 1330 Vierra Mouth All data are missing from Feb 02 0730 through 1130 and from Feb 03 0100 through Feb 04 1130 due to a loss of data on the sonde for an unknown reason. 4 NTU was added to all turbidity data from the beginning of the month through the end of the deployment (Feb 02 0630) because numerous values were negative probably due to a poor calibration in DI. 4 NTU was added to all turbidity data from Feb 02 1200 through Feb 03 0030 because numerous values were negative probably due to a poor calibration in DI. 19 NTU was added to all turbidity data from Feb 04 1200 through Feb 28 2330 because numerous values were negative probably due to a poor calibration in DI. The following turbidity data were deleted because they were anomalously high or negative; Feb 06 1830 Feb 07 1200-1230, 1930 Feb 08 0430, 1800 Feb 09 1400 - 1430 Feb 21 1330 DO data were deleted from Feb 15 0800 through the end of the month due to a membrane puncture that happened at this time. DO data are suspect at the beginning of the month through the end of the first deployment (02/04 1130) because there is a discontinuity between the end of the first deployment and the beginning of the second deployment. The data were not deleted because the post deployment check was 103% in 100% saturated air. All pH data are deleted from the beginning of the first deployment through end of deployment 02/02 0630 because of a malfunctioning probe. All ph data are deleted 02/02 1200 through 02/03 0030 because of a malfunctioning probe. March 1-30, 2002 Sampling Period Azevedo Pond + 14 NTU was added to turbidity data from the beginning of the month through the end of the first deployment (Mar 25 1200) because there were numerous negative values due to a poor calibration in DI. Turbidity data were deleted from the beginning of the second deployment (03/25 1230) though the end of the month because no probe was deployed. The following turbidity data were deleted because they were anomalously high or negative; Mar 10 1100 Mar 14 0700 Mar 22 0930 There was a significant decrease in salinity corresponding to a significant rain event (14 mm) on Mar 17. North Marsh Turbidity data are missing during the second deployment (02/19 1130 through 03/18 1100) because no probe was deployed. Salinity data were deleted at the end of the first deployment (03/17 0130 through 03/18 1100) because they were not congruous with the following deployment. The following turbidity data were deleted because they were anomalously high or negative; Mar 18 2200 Mar 20 1830 Mar 25 1700 Mar 27 0000 Mar 28 0230, 0300, 0500 Mar 30 0530, 2200 Mar 31 1630-1730 South Marsh The pH data are suspect at the end of the first deployment because they are incongruous with the following deployment and they are generally decreasing. Salinity data are suspect Mar 02 0200-0230 because there is a sharp drop then back in line with the rest of the data. The following turbidity data were deleted because they were anomalously high or negative; Mar 02 0000 Mar 03 0730 Mar 05 1230 Mar 09 1800 Mar 10 0630 Mar 12 1800 Mar 16 1830, 2200 Mar 17 1230 Mar 19 1000, 1600, 1700 Mar 21 1630 Mar 25 2130 Mar 27 1900, 2330 Mar 28 0100-0530 Mar 29 0200-0600 Mar 30 0330-0500 Mar 31 0500 Turbidity data are suspect towards the end of the month because of high concentrations. There was a slight rain of approximately 2 mm which may have caused some higher turbidity values during this time. Vierra Mouth Salinity data were deleted from mar 09 0030 through the end of the month because the conductivity probe malfunctioned. DO% and DO mg/L data were deleted from the beginning of the month through the end of the deployment (Mar 04 1230) because of previously mentioned membrane puncture. 16 NTU was added to all turbidity data the entire month because numerous values were negative probably due to a poor calibration in DI. The following turbidity data were anomalously high; Mar 13 0500 Mar 14 0800 Mar 16 1900 Mar 17 0000 Mar 23 1230 Mar 24 0800 Mar 25 0600 Mar 26 1300 Mar 27 0600,0730, 1300 Mar 28 0030 Mar 30 0130 April 1-30, 20020 Sampling Period Azevedo Pond Turbidity data were deleted from the beginning of the month though the end of the first deployment (April 22 0830) because no probe was deployed. Salinity data are suspect from the beginning of the month through the end of the first deployment (April 22 0830) because the data are incongruous with the following deployment and the post deployment check read 44.21 ms/cm in 53 ms/cm. The following turbidity data were deleted because they were anomalously high or negative; Apr 26 1130 Apr 28 1930 North Marsh 4 NTU was added to all turbidity data the entire month because numerous values were negative probably due to a poor calibration in DI. The following turbidity data were deleted because they were anomalously high or negative; Apr 01 06:00, 22:00 Apr 03 07:00, 14:30, 16:00, 17:30, Apr 05 01:00 Apr 06 02:30, 1400, 17:00, 20:00, 21:30, 23:30 Apr 07 14:30-15:00, 17:00, 21:00 Apr 16 16:00 Apr 17 07:30 Apr 19 15:00 Apr 20 05:30 Turbidity data were deleted from April 08 1000 through the end of the deployment April 15 1100 because they were erratic and post deployment data read 37.2 in 100 NTU, and from April 22 2100 through the end of the month because values were slowing increasing and erratic. Salinity data are suspect from the beginning of the month through the end of the Deployment (04/15 1100) because values are at first slowly decreasing then slowly increasing. Depth data are suspect from approximately April 10 0000 through the end of the Deployment (04/15 1100) because they slowly decrease through the end of the deployment. pH data are suspect from approximately April 26 0730 through the end of the deployment (05/13 1000). South Marsh Salinity data were deleted from the beginning of the second deployment (04/08 1230) through the end of the month because data were very low and the post calibration was out of range reading 223 ms/cm in 53 ms/cm. DO data were deleted during from Apr 21 0330 through the end of the month because of a high and low spike in the data indicating the membrane was punctured. 11 NTU was added to turbidity data from the beginning of the second deployment (April 08 1200) through the end of the month because numerous values were negative probably due to a poor calibration in DI. Turbidity data were deleted from April 01 0200 through the end of the first deployment (04/18 1200) and from April 28 1130 through the end of the month because values were high erratic. The following turbidity data were deleted because they were anomalously high or negative; Apr 18 07:00 Apr 20 01:30, 07:30 Apr 21 05:00-06:00, 08:00 Apr 24 23:30 Apr 26 08:00 Apr 27 02:00 Vierra Mouth Salinity data are deleted from the beginning of the month through the end of the first deployment Apr 01 1100 due to previously mentioned probe malfunction. DO data are deleted from Apr 06 1000 through the end of the second deployment Apr 29 0830 because the membrane was found punctured upon recovery and there was a sharp decrease in the values on Apr 06 which is most likely when it occurred. DO data are suspect from the beginning of the month through the end of the first deployment Apr 01 1100 because they are not congruous with the following deployment. 3 NTU was added to all turbidity data from the beginning of the month through the end of the second deployment Apr 29 0830 and 7 NTU was added the turbidity data from Apr 29 1100 through the end of the month because numerous values were negative probably due to a poor calibration in DI.

DO data are suspect from the beginning of the second deployment though May 16 0400 because data are not congruous with previous deployment but after this data look ok. pH data are missing from the beginning of the month through the end of the deployment (05/13 1000) due to a malfunctioning probe. Upon retrieval of the second deployment, on 06/10 0830, the sonde was noted to be covered in mud probably due to a large sedimentation which occurred beginning approximately May 17 when the pH probe began showing signs of being covered in mud. The other probes began showing signs later. The following are when these probes data were deleted. Salinity and Spec. Cond. data are deleted from May 24 2000 through the end of the deployment (06/10 0830) because data are slowly decreasing probably from being covered in mud. DO data are deleted from May 24 1730 through the end of the deployment (06/10 0830) because data make a sharp drop probably due to the probe being covered in mud. pH data are missing from May 17 1500 through the end of the deployment (06/10 0830) because data are slowly decreasing probably due to probe being covered in mud. 28 NTU was added to all turbidity data the entire month because numerous values were negative probably due to a poor calibration in DI. Turbidity data were deleted from May 15 1800 through the end of the month because values were increasing suggesting they were being covered with mud. South Marsh All data are missing from May 07 1600-1630 because the turbidity probe was added to the sonde and brought to the lab to calibrate. DO data are deleted from the beginning of the month through the end of the first Deployment (05/06 0900) due to previously mentioned membrane puncture. Turbidity data are missing from the beginning of the month through the end of the first deployment (05/06 0900) because of previously mentioned probe malfunction. Turbidity data are also deleted from the beginning of the second deployment May 06 1330 through May 07 1530 because no probe was deployed, probe was added to sonde at May 07 1630. 10 NTU was added to all turbidity data from May 07 1700 through the end of the month because numerous values were negative probably due to a poor calibration in DI.

Data are missing due to equipment failure where no probes were deployed, maintenance and calibration of equipment, elimination of obvious outliers or elimination of data due to calibration problems (both pre and post). For more details on deleted data, see the Data Anomalies Section. To find out more details about missing data, contact the Research Coordinator at the site submitting the data. LINEAGE/PROCESS STEP: PROCESS DESCRIPTION: Additional Description: Entry verification The Centralized Data Management Office re-processed all SWMP water data collected from 1995-2002 to include an identifying station code (three letter reserve code, two letter sampling site code and data type code), a four digit year date stamp (mm/dd/yyyy) and a corrected time column (hh:mm). With the new format, the use of periods to denote deleted or missing data has been abandoned. Hence, all periods contained in the SWMP water data collected prior 2003 were removed and left blank. : Data are uploaded to the PC from the YSI Model 6000 and 6600 datasonde and graphs are produced and examined using the Ecowatch program software. Data are also uploaded in a comma-delimited format from the YSI to the PC. Edited files are created by removing headers, footers, and spaces on a PC in Excel 5.0. Suspect data are evaluated using QA/QC Excel 5.0 macros (version 3.0) from CDMO. The CDMO cdmomac3.xls macro will allow the user to automatically format column widths to the correct number of decimal places based on YSI sensor specifications. It also allows the user to QA/QC each data logger generated file for missing data points, fill all cells that do not contain data with periods, and find all data points that fall outside the range of what the data logger is designed to measure (outliers). The CDMO import.xls macro will allow PC users with 30- minute data to automatically create a monthly Excel file from a two-week deployment and insert periods for missing data. In addition, in November 1999 a graphing capability was added to this macro allowing users to produce single parameter and missing data point graphs on a monthly basis. Edited and raw data are archived at Elkhorn Slough NERR then uploaded to CDMO NERR server. John Haskins is responsible for the editing and archiving of data. PROCESS DATE: 20060209
