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 three 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 purpose of this research is to identify the base parameters for Elkhorn Slough by using South Marsh as the control site and the other two sites are impacted sites and monitored for possible future problems.
SUPPLEMENTAL INFORMATION:
Associated researchers and projects The following are brief descriptions of research projects in Elkhorn Slough as of June 1999. 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 Agroecology 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.

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) (36( 49' 04.72" N, 121 44' 21.95" W) 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) (36( 50' 44.41" N, 121( 45' 13.50" W) is in a pond, which 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. NM (North Marsh) (36( 50' 04.68"N, 121( 44' 18.19"W) is located in between South Marsh and Azevedo Pond. This site is impacted by both agricultural and urban runoff. Azevedo Pond ranged in temperature between 3.5 C and 35 C in the summer and averaged 16 C. Salinity ranged from 1 ppt during rain events to 60 ppt during summer evaporation and averaged 47 ppt. DO% ranged from 0% to 302% and averaged 84%. The tidal range is approximately 1 m, and the depth is approximately 1.5m. PH ranged from 6.9 to 9.8 with an average of 7.9. Turbidity ranged from 0 to 676 NTU with an average of 13. The bottom habitat is fine sediments covered in ulva and other benthic algae. Freshwater input is heavy during the winter and is from the neighboring agricultural field. South Marsh ranged in temperature between 9.8 C and 23.7 C in the summer and averaged 15.8 C. Salinity ranged from 1 ppt during rain events to 35 ppt during summer evaporation and averaged 30 ppt. DO% ranged from 2% to 184% and averaged 86%. The tidal range is approximately 3 m and the depth is 3.5 m. PH ranged from 7.2 to 8.6 with an average of 7.9. Turbidity ranged from 0 to 134 NTU with an average of 12 NTU. The bottom habitat is slightly larger grain sediments because of the higher current area. Freshwater inputs are from surrounding upland area and only occur during the winter. North Marsh ranged in temperature between 8.5 C and 29.4 C in the summer and averaged 17.6 C. Salinity ranged from 12 ppt during rain events to 45 ppt during summer evaporation and averaged 33 ppt. DO% ranged from 0% to 363% and averaged 81%. The tidal range is approximately 1 m and depth is approximately 1.5m. PH ranged from 6.2 to 9.4 with an average of 8.0. Turbidity ranged from 0 to 161 NTU with an average of 11 NTU. The bottom habitat is fine sediments covered in ulva and other benthic algae. Two small creeks run into this marsh and only run in the winter.

ATTRIBUTE ACCURACY REPORT: Anomalous/Suspect Data January 1-31, 2000 Sampling Period Azevedo Pond Data for this month were compiled from two deployments. The first ended Jan 02 1600 and the second one began Jan 3 0830. These turbidity data are missing during these times because they were anomalously high; Jan 04 1530 Jan 25 2130, 2300-2330 Jan 26 0030, 0130, 0430, 0700, 1030-1100, 12:30, 1430 ... Turbidity, specific conductivity, and salinity data are suspect beginning Jan 23 0700 to end of month due to high values but these were most likely due to the significant rain event that occurred during this time. North Marsh Data for this month were compiled from two deployments. The first ended Jan 29 1530 and the second one began Jan 29 1600. Turbidity data were deleted Jan 10 2330, Jan 11 0000, and Jan 23 0430 because they were anomalously high. South Marsh Data for this month were compiled from two deployments. The first ended Jan 14 0730 and the second one began Jan 14 1530. Turbidity data was negative and/or zero during these times: Jan 01 00:30, 07:00-07:30, 21:00 Jan 02 01:00 Jan 03 01:00 Jan 04 11:30, 23:00 Jan 05 03:30 Salinity and specific conductivity are suspect from Jan 01 0000 through the end of the first deployment on Jan 14 0730 because values muted and slowly drifting. Data were not deleted. February 1-29, 2000 Sampling Period Azevedo Pond Data for this month were compiled from two deployments. The first ended Feb 04 0830 and the second one began Feb 05 1000. Turbidity data are missing Feb 03 1800 and Feb 22 2300 due to large spikes most likely due to debris. The following are when depth was negative, 02/11/00 18:00 02/20/00 05:30-07:30, 21:00-21:30 The following turbidity data are missing because they were above 1000 NTU 02/11/00 21:30 02/15/00 03:30-05:00 The point that show zero is actually greater than -0.5 and show up with the macro but is rounded to zero with the formatting Salinity specific conductivity data low beginning Feb 11 1700, but this was due to a significant rain event. No data were deleted for this parameter. Turbidity had a significant spike Feb 11 2000 through Feb 12 0030 and Feb 13 1130 through Feb 17 0030 due to a significant rain event. See missing data as to which data were deleted. North Marsh Data for this month were compiled from two deployments. The first ended Feb 29 1130 and the second one began Feb 29 1230. Turbidity data are missing Feb 01 0730, Feb 03 0830, and Feb 14 0500-0530 due to debris. South Marsh Data for this month were compiled from two deployments. The first ended Feb 14 1100 and the second one began Feb 14 1200. Turbidity was deleted Feb 22 1630 due to a high spike probably due to debris.

The first ended Apr 22 0930 and the second one began Apr 22 1000. These turbidity data were deleted because they were anonymously high Apr 14 1800 Apr 18 1400 Apr 23 1600 Apr 29 0000 DO% and DO mg/L data were deleted during these times due to negative readings; Apr 02 04:30-05:00 Apr 07 06:00 Apr 08 06:30, 08:30 Apr 09 07:00 Apr 30 03:00-04:30 Turbidity data suspect due to negative and/or zero values during these times: Apr 01 04:00, 11:30-12:30, 14:00-14:30, 16:00 Apr 02 11:30, 13:00 Apr 07 09:30-10:00 Apr 08 05:30, 07:30, 12:00 Apr 09 07:30, 09:30, 11:30-13:00 Apr 10 07:30, 09:30-10:30, 11:30 Apr 11 13:30 Apr 12 11:00-12:30, 14:30, 16:30 Apr 14 03:00, 16:30 Apr 15 03:00-04:30, 10:00, 13:30-15:30, 17:30-18:00 Apr 16 03:00-06:30 Apr 17 17:00-19:00 Apr 18 11:00-11:30, 14:30-20:30 Apr 19 01:30, 03:00, 04:00-05:30, 06:30, 07:30-09:00, 10:30-11:00, 13:00, 14:30, 15:30-16:00, 17:00, 18:00-20:00 Apr 20 04:30-06:30, 08:00, 10:00, 11:00-12:00, 14:00-17:00, 18:30-20:30 Apr 21 02:30, 04:30, 05:30, 06:30, 07:30, 11:30, 12:30, 14:00-17:30, 18:30- 20:30 Apr 22 03:30, 04:30-05:00, 06:00-08:00, 09:00-09:30, 10:30, 12:00, 15:00, 17:00, 18:00-18:30, 19:30-20:30 Apr 23 06:00-06:30, 07:30-13:00 Apr 24 07:00-09:00, 10:00-14:30 Apr 25 06:00, 07:00, 08:00, 09:00, 10:00-10:30, 11:30-14:00, 15:30-16:00, 18:00, 21:00, 22:30-23:30 Apr 26 00:30-01:00, 08:00-16:00, 23:30 Apr 27 00:30-01:00, 07:00, 09:00, 10:00-11:30, 12:30-13:30, 14:30-17:00 Apr 28 00:30-03:00, 05:30, 10:00-14:30, 16:30 Apr 29 01:00-04:00, 09:30, 11:00-17:30 Apr 30 00:00-06:00, 09:00, 10:00-11:00, 12:00-13:00, 14:00-18:30 The points that show zero are actually greater than -0.5 and show up with the macro but are rounded to zero with the formatting. South Marsh Data for this month were compiled from two deployments. The first ended April 11 1830 and the second one began Apr 11 1900. Turbidity data was deleted Apr 01 1630, Apr 05 2300 and Apr 23 0830 due to a high spike most likely due to debris. DO data experienced a sharp increase Apr 29 0330 and stayed high through the end of the month. All data were deleted. Turbidity data suspect during these times due to negative and/or zero readings: Apr 12 04:00, 20:00 Apr 13 06:30 Apr 14 20:30 Apr 15 08:00-09:00, 20:30, 21:30-22:30 Apr 16 09:00-10:00, 20:30, 21:30-22:00 Apr 17 09:30-11:00, 21:30, 22:30 Apr 18 23:30 Apr 20 23:00 Apr 21 00:00 Apr 22 00:30 Apr 23 01:00-01:30 Apr 24 01:00-01:30, 20:00-20:30, 21:30 Apr 25 02:30, 23:30 Apr 26 02:30-03:00 Apr 27 04:30 The points that show zero are actually greater than -0.5 and show up with the macro but are rounded to zero with the formatting. Salinity and conductivity are suspect from the beginning of the month to the end of the first deployment because of a sharp increase at the beginning of the next deployment Apr 11 1900. Data were not deleted because relative data are still apparent. May 1-31, 2000 Sampling Period Azevedo Pond Data for this month were compiled from two deployments. The first ended May 02 1300, the second one began May 02 1330 and ended May 30 2030. Turbidity data was deleted May 14 1130 because of anonymously high reading due to debris. North Marsh Data for this month were compiled from two deployments. The first ended May 22 0900 and the second began May 22 1000. Depth data was suspect from May 03 2200 through the end of the deployment because of erratic readings due to unknown reasons. Depth data were deleted during these dates because readings were anonymously high: May 08 1700, May 14 1630, May 16 0200-0230, and May 18 0130 The following turbidity data are deleted because they were anomalously high: May 02 2100, May 03 2130, May 04 1700, 2030-2100, May 05 0000, May 07 0900, May 08 2130, May 18 0730, May 19 0100, May 19 1100, May 25 1030, May 28 1500, and May 30 1430. DO% and DO mg/L data were deleted because of negative readings: May 01 03:00-06:00 May 02 05:30-06:00, 07:00 May 03 04:00-06:30, 07:30 May 04 03:00, 04:00-06:00 May 06 04:00-06:00 May 07 06:00 May 08 06:00-06:30 May 12 01:30 May 13 03:00 May 14 04:00-05:00 May 16 06:30 May 20 04:00, 05:00, 06:30 May 21 04:30-07:30 May 22 04:30-07:30 Turbidity data suspect during these dates due to negative and/or zero values: May 01 02:00-06:30, 10:00-14:00, 15:00-18:30 May 02 02:30-14:30, 16:00-19:30 May 03 02:00-08:00, 13:30-18:00 May 04 03:30-05:00, 06:00-09:00, 14:30-16:30, 18:30 May 05 03:30, 04:30-10:30, 16:00, 18:30-19:30 May 06 04:00-08:00, 09:00-10:30, 17:30, 19:00-19:30 May 07 06:00-08:30, 09:30-10:00, 11:00-13:00, 16:00, 19:00 May 08 06:00, 07:30-08:00, 09:00-09:30, 10:30, 11:30, 12:30-13:00 May 09 07:30-09:00, 10:00, 11:00-11:30, 13:00 May 10 11:00-14:00, 15:00, 22:30 May 11 00:00-00:30, 01:30, 07:30, 09:30-15:30, 23:30 May 12 00:00-03:30, 08:30, 10:00, 11:30, 13:00, 15:00, 16:00 May 13 02:00, 03:30, 10:00, 13:00 May 14 02:00-05:30, 12:30, 15:30 May 15 04:00, 05:00-05:30, 13:00-13:30, 15:30-17:00 May 16 03:00-08:30, 14:30, 15:30, 16:30-18:00 May 17 02:30-03:00, 05:30-08:30, 11:00, 14:00, 15:00, 16:00-17:30 May 18 04:30-05:30, 06:30, 09:00-09:30 May 19 06:00-06:30, 07:30-10:30 May 20 06:30, 08:30-09:30 May 21 12:00 The points that show zero are actually greater than -0.5 and show up with the macro but are rounded to zero with the formatting. South Marsh Data for this month were compiled from two deployments. The first ended May 09 1400 and the second began May 09 1430. Salinity and conductivity data are suspect from the beginning of the month through the end of the deployment May 09 1400 due most likely to drift. Data were not deleted. These data are also suspect from the beginning of the second deployment through the end of the month because there is a general decreasing trend as the probe is drifting. Data were not deleted. PH data are suspect for this month because the second deployment had significantly higher values than the first deployment. This may have been due to drift from the first deployment. Data were not deleted. Turbidity data suspect during these times due to negative and/or zero values: May 08 01:00 May 09 17:00 May 10 02:00-02:30 May 11 18:00 May 12 19:30 May 13 20:30-21:00 May 14 21:00 May 16 21:30-22:00 Turbidity data were deleted May 15 1530 and beginning May 22 1200 through the end of the month because data were erroneously high. June 1-30, 2000 Sampling Period Azevedo Pond Data for this month were compiled from one deployment. This began Jun 03 1730 and ended Jun 14 1000. The next deployment did not record data because of operator error. Depth data are missing for the entire month because of significant drift and negative values. Turbidity data were suspect Jun 09 0200 and Jun 10 0730, because values were negative and or zero. The following DO% data were deleted because of negative values; Jun 09 01:30-02:30 Jun 10 01:00-05:00 Jun 11 02:00-07:30 Jun 12 02:30-06:30 Jun 13 04:30-05:30 Jun 14 04:00-06:30 North Marsh Data for this month was compiled from two deployments. The first ended June 12 1030 and the second one began June 12 1100. Depth values were suspect beginning Jun 27 2230 through Jun 28 1600 due to irregular drop in values. Data were deleted.

Depth values were deleted beginning Jun 27 2230 through Jun 28 1600 due to irregular drop in values. The following turbidity data were deleted because of anonymously high values; Jun 04 0800 Jun 05 0100 and 0530 Jun 08 1830-1930, 2030, 2230-2330 Jun 09 1130 Jun 10 0530-0800, 1800, 2030,2130-2330 Jun 11 0000-0030 Jun 27 0400 Jun 30 1900 South Marsh Data for this month were compiled from two deployments. The first ended June 05 1600 and the second one began June 05 1630. Salinity and conductivity data are suspect from the beginning of the month to the end of the deployment Jun 05 1600 due to previously mentioned probe drift. These turbidity data were negative and/or zero: 06/06/00 0200 06/19/00 0000 DO% and DO mg/L were deleted from the beginning of the month through Jun 05 1600 the end of the first deployment because of previously mentioned membrane failure. These data were also deleted Jun 08 1330-1430 because values were negative. The following turbidity data were deleted because of high spikes in the data; Jun 01 0730 Jun 02 1930 Jun 05 0800 Jun 25 1030 July 1-31, 2000 Sampling Period Azevedo Pond Data for this month were compiled from one deployment, which began Jul 11 1730.

These turbidity data were greater that 1000 NTU, therefore data were deleted: 08/14/00 06:00:00 08/16/00 20:30:00 08/27/00 23:00:00 DO% and DO mg/L were deleted during the following times because values were negative: Aug 04 22:30-23:30 Aug 05 00:00-00:30, 23:00-23:30 Aug 06 00:00-08:00, 23:30 Aug 07 00:00-09:30 Aug 19 06:30, 23:00-23:30 Aug 20 00:00-00:30, 02:00, 03:30-07:00, 08:00, 23:30 Aug 21 00:00-08:00 Aug 22 01:00-01:30, 02:30-08:00, 09:00 Aug 23 00:00-09:30 Aug 24 00:30-08:00 Aug 25 02:00-08:30 Aug 26 03:00-08:00 Aug 27 05:00-08:30 Aug 28 06:00-07:30 Aug 29 07:30 These turbidity data were deleted because they were high spikes Aug 10 1700 Aug 14 0600 Aug 16 2030 Aug 18 2330 Aug 20 0300 Aug 24 0530, 1630 Aug 25 0330, 1300-1330, 1900-1930 Aug 27 2230, 2300 North Marsh Data for this month were compiled from three deployments. The first ended August 08 1400, the second one began Aug 08 1430 and ended Aug 28 1500, the third one began Aug 28 1500. PH data are suspect from the beginning of the month to the end of the first of the deployment Aug 08 1400 because post calibration was slightly off and the next deployment saw higher values. PH data was also suspect towards the end of the second deployment because values made a significant decrease then were muted. Data was deleted Aug 23 1730-Aug 28 1530. South Marsh Data for this month were compiled from two deployments. The first ended Aug 15 1000 and the second one began Aug 15 1030. Salinity and conductivity data are suspect towards the end of the first deployment because of a discrepancy of the end of the first deployment and the beginning of the first deployment. This was probably due to drift of probe values but it is not possible to determine when it began. These data were not deleted. PH data are also suspect at the end of the first deployment because values at the beginning of the second deployment are approximately 0.2 pH units below those of the end of the first deployment. Data were not deleted. September 1-30, 2000 Sampling Period Azevedo Pond Data for this month were compiled from two deployments. The first ended Sept 05 1100 and the second one began Sept 06 1100.

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 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. Removing headers, footers, and spaces on a PC in Excel 5.0 creates edited files. Suspect data are evaluated using QA/QC excel 5.0 macros (version 3.0) from CDMO. Missing data from YSI maintenance are inserted into the spreadsheet and are denoted by periods (.). Edited files are merged to create one full month of data. 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
