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:
The purpose of the monitoring program at CBM NERR is to conform to the NERR SWMP monitoring program looking at trends in water quality over both temporal and spatial scales. Observed effects of water quality, habitats and living resources in the river channel site and the nearby emergent tidal fresh marshes are being studied using various comparative ... field sampling methods with the backdrop of long term high resolution data from four representative fixed monitoring sites. Water quality measurements were taken every 15 minutes from April through December 2003 at the Jug Bay Wetlands Sanctuary (RR) site that conform to seasonal measurements collected each year since 1995. In 2003, the Patuxent River Park (PR)site was moved to Mataponi Creek (MC), and the CBM NERR expanded its water quality component by two (2) stations. These new stations were installed at Otter Point Creek (OC) and Ironpot Landing (IP), and measurements were taken every 15 minutes from April through December of 2003.
SUPPLEMENTAL INFORMATION: Associated researchers and projects The Jug Bay Wetlands Sanctuary staff has been collecting weekly to monthly temperature, salinity, dissolved oxygen, and nutrient samples at the same location as the data logger at JB until 2003. The Anita C. Leight Estuary Center at Otter Point Creek, in conjunction with CBNERR/MD staff has also been collecting bi-weekly to monthly temperature, salinity, dissolved oxygen, total suspended solids, chlorophyll a, and nutrient samples at the same location as datalogger OC for 2003. Additional discrete data is also available that provides increased spatial coverage of many of the same parameters around both RR and OC sites for 2003. Other remarks/notes Hurricane Isabel swept through the area on September 19, 2003 influencing water quality data, especially depth, for all sites.

SPATIAL DATA ORGANIZATION INFORMATION: Indirect Spatial Reference: Site location and character The Chesapeake Bay Maryland NERR has three components in Maryland's portion of Chesapeake Bay. Monie Bay is a mesohaline region on the lower Eastern Shore; Otter Point Creek is a tidal freshwater tributary of the Bush River; and Jug Bay is part of the freshwater portion of the Patuxent River. Three (3) of the data loggers during 2003 were within the Jug Bay component and one (1) logger was in the Otter Point Creek component. Mataponi Creek (MC) 38° 44.599'N, 76° 42.446'W (NAD83) or 38.74331667, -76.70743333 (GIS format) Site MC is located in a small tributary off the upper tidal headwaters of the Patuxent River, Maryland. MC is 2.4 km upstream of the mouth, midchannel in the creek, which is approximately 7m wide. The southern bank is steep and covered mainly with hardwood trees while the Northern bank is tidal marsh. The sonde was deployed vertically in a perforated PVC pipe. Average depth at this site is roughly 0.7 meters with a mean tidal fluctuation of approximately 0.6 m.. The YSI is deployed 0.25 m off of the creek bottom. Salinities at this site rarely exceed 0.1 ppt. The bottom habitat is soft sediment, and SAV grassbeds are abundant during the summer months. Because this site is located along the main channel of the Mataponi Creek, water quality is reflective of the general quality of water flowing along the main portion of the creek. The SAV community as this site is seasonally very dense and thus water quality is thought to be strongly influenced by the presence of SAV during the summer months. Railroad Bridge (RR) 38° 46.877'N, 76° 42.822'W (NAD 83) or 38.78128333, -76.7137 (GIS format) Jug Bay is a 722-acre tidal estuary providing a narrow transition zone between brackish marshes and upland freshwater wetlands. The broad, shallow waters of Jug Bay support a profusion of freshwater plants and animals. Vegetation crowds the river channel and forms an interlaced pattern of tidal and nontidal marshes, swamps and forested wetlands surrounded by upland woods and fields. Site RR is located in the mainstem of the upper tidal headwaters of the Patuxent River, Maryland. The site is slightly upstream (roughly 0.3km) from Jackson's Landing at the Patuxent River Park (previous PR site). This section of the Patuxent river is approximately 70m wide and average depth at the site is 1.4m. The YSI is deployed 0.25 m off of the river bottom. Bottom habitat is soft sediment, and grassbeds are evident in the area during summer months. Mean tidal fluctuation is approximately 0.6 m. Salinity in 2003 ranged from 0.05 - 0.4 ppt. In 2003 this site was moved from 38° 46' 50.6" N, 76° 42' 29.1" W (Jug Bay) to its present location because of the shallow nature of the old site. The new site location (RR) is at the end of the old railroad bed and is deployed vertically in a perforated PVC pipe near midchannel of the Patuxent River. Because this site is located along the main channel of the Patuxent River, water quality is reflective of the general quality of water flowing along the main portion of the river. The site is roughly 1km downstream of the confluence of the Western Branch tributary and the Patuxent River Mainstem, thus water quality is influenced by Western Branch. A large wastewater treatment plant (averaging 10-20 mgd ) discharges directly into the Western Branch tributary of the Patuxent River just upstream of IP. Iron Pot Landing (IP) 38° 47.760'N, 76° 43.248' W (NAD 83) or 38.796, -76.7208 (GIS Format) Site IP is located 2.09km from the mouth of Western Branch. IP is attached vertically off of a small pier near midchannel of the river and has an average depth of 1.6m. The YSI is deployed 0.25 m off of the river bottom. The site is roughly 1km downstream of a large (10-20 mgd) wastewater treatment plant effluent. The river is approximately 15m wide and flows through extensive riparian buffers. Both banks of the river are flanked by hardwood flora. Tides are semi-diurnal and mean tidal fluctuation is approximately 0.6 m. Salinity at this site is generally 0.1 ppt. Bottom habitat is soft sediment, and grassbeds are evident during the summer months. This site is part of the NERR build out and is new for 2003. Otter Point Creek (OC) 39° 27.047'N, 76° 16.474'W (NAD 83) or 39.45078333, -76.27456667 (GIS Format) Otter Point Creek is a tributary of the Bush River in the upper Chesapeake Bay and consists of 672 acres of open water, tidal marshes, forested wetlands and upland hardwood forests, surrounded by major highways, large residential communities, and heavy commercial and industrial development. Site OC is located approximately 0.3km from the Anita C. Leight Estuary Center. OC is deployed vertically in a perforated PVC pipe and has an average depth of 0.7m. The YSI is deployed 0.25 m off of the creek bottom. Bottom habitat is extremely soft sediment, and grass beds inundate the site during summer months. Salinity at this station rarely rises above 0.1 ppt. Tides in Otter Point Creek are semi-diurnal and have a mean range of about 0.3 m. The average water levels are generally lower in the winter due to north and northwest winds that increase the egress from Chesapeake Bay. The sonde was periodically exposed to very low tides, and sediments at the site are extremely fine and flocculent. Because of the shallowness of the tidal marsh, coupled with the dramatic daily changes in the depth and width of the stream, deployments at the site presented many problems. These problems included periodic exposure of the sonde, very high turbidity and sedimentation rates associated with tidal infiltration and wind and wave generated resuspension which caused severe fouling of the probes. Water quality at the site represented extreme shallow water habitats. Thus it is not uncommon to see very large fluctuations in temperature and dissolved oxygen at this site ranging from complete anoxia to full saturation, due in part to the shallow nature of the site and the effects of marsh processes on water quality. Additionally, the site was dominated by dense SAV communities from June-October 2003 and thus water quality conditions were likely influenced by the presence of these macrophytes.

Reason for spike unknown. October 2003 Negative depths retained in data set for month of October because salinity showed meter to be in water, possibly changes in pressure caused negative readings. (Depth Not Vented) In-situ match-up readings on 10/14/03 exhibit high deviation from check meter and Hydrolab instrument. It is likely due to variation in depth rather than instrument malfunction. SAV beds at sight make it difficult to put YSI, check YSI, and Hydrolab at same depth. Data retained but should be considered suspect. 10/14/03 12:30:00 Following record logged by check meter (Babs), meter does not have depth sensor. 10/14/2003 11:30:00 pH reading low in post-cal and in-situ matchups. pH data deleted for the following dates and times. 10/14/2003 11:30:00 - 10/22/2003 11:45:00 Instrument out of water, data deleted: 10/28/2003 11:30:00 November 2003 Negative depths retained in data set for month of November because salinity showed meter to be in water, possibly changes in pressure caused negative readings.

Step changes in depth were evident throughout the deployment year because depth was not calibrated to zero and a non- vented depth probe was in use as opposed to a vented depth probe which was unavailable. April 2003 None May 2003 Turbidity spikes deleted due to transient material blocking optic. 05/12/2003 09:00:00 - 05/12/2003 11:45:00 Turbidity matchup for retrieval of the sonde on 5/28/03 is off. Determined the approximate point where upward drift started and deleted all subsequent data for that deployment. 05/23/2003 11:00:00 - 05/28/2003 10:15:00 Depth measurements were lower than normal after deployment on 5/28 10:30 through 6/3 1230. Sonde appeared to be in the water during this time. June 2003 Depth measurements were lower than normal after deployment on 5/28 10:30 through 6/3 1230. Sonde appeared to be in the water during this time. The following negative depth readings were removed. The data recorded at these times was not deleted because the meter was not out of the water. There may have been something blocking the depth sensor. 06/03/2003 12:30:00 - 12:45:00 Depth measurements suddenly spiked after deployment on 6/3 12:45 through 6/3 1415 but returned. Sonde appeared to be in the water during this time. The following turbidity data point was found as an outlier by the NERR macro, but was not deleted. The high turbidity value was a result of a rain event. There may have been a sewage overflow upstream. Turbidity values did not return to under 50 NTU until 6/28/2003 at about 14:00:00. 6/27/2003 19:45:00 Turbidity spikes deleted due to transient material blocking optic. 06/14/2003 08:45:00 06/16/2003 00:45:00 - 06/17/2003 09:45:00 06/20/2003 04:45:00 06/20/2003 10:00:00 July 2003 Erratic Turbidity data removed, likely due to wiper malfunttion. 07/01/2003 11:00:00 07/07/2003 00:30:00 - 07/07/2003 23:45:00 Turbidity spikes deleted due to transient material blocking optic. 07/20/2003 14:30:00 - 07/22/2003 08:45:00 August 2003 Erratic Turbidity data deleted. Could be wiper malfunction or something caught on probe or wiper. 08/04/2003 15:15:00 - 08/05/2003 09:30:00 The following reading was taken from check sonde. The deployed meter was out of the water for data retrieval. The check sonde used was "CINDY," which does not have a depth sensor. Therefore, we do not have a depth reading for this data point. 08/12/2003 10:00:00 Turbidity spikes deleted due to transient material blocking optic. 08/22/2003 02:30:00 08/30/2003 01:15:00 Datalogger out of the water for the following dates and times. Data deleted. 08/26/2003 11:30:00 September 2003 Erratic Turbidity data removed. Likely something caught on probe or wiper is blocking optic. 09/22/2003 00:00:00 - 09/23/2003 10:30:00 October 2003 The following reading was logged with check meter "Ophelia." The deployed meter was out of the water for data retrieval. No Depth recorded for this data point. 10/01/2003 10:00:00 DO membrane punctured. The following DO data set deleted. 10/07/2003 09:30:00 - 10/14/2003 09:45:00 Drop in dissolved oxygen on 10/20/2003 18:30:00 (13.7%). Data suspect, but retained. Check sonde (BABS) in water for the following 2 readings. The deployed sonde was out of the water for data retrieval. "Babs" does not have a depth sensor, so there are no depth readings for these intervals. 10/14/2003 10:00:00 - 10:15:00 The deployed sonde, "HeMan," had a bad DO membrane, so it was not redeployed. The check sonde could not be deployed immediately because it was needed for other sites. "Babs" was returned at Iron Pot Landing at the end of the field day. It was re-deployed at 12:30:00. Thus there is no data for the following period: 10/14/2003 10:00:00 - 12:15:00 Turbidity spikes deleted due to transient material blocking optic. 10/16/2003 00:15:00 10/16/2003 01:30:00 10/17/2003 04:30:00 10/18/2003 01:15:00 10/18/2003 18:00:00 10/19/2003 17:30:00 10/30/2003 05:00:00 Sonde was out of water for the following reading. Data was recorded with check sonde, but determined to be anomolous. All parameters were removed for the following sates/times: 10/28/2003 12:45:00 No Depth data recorded for the following period because we had to deploy a backup sonde because the DO membrane was punctured on the deployed meter. The backup sonde ("Babs") had no depth sensor. 10/14/03 12:30:00 - 10/22/03 10:00:00. November 2003 No data logged for the following intervals.

Deleted Data Missing Data Missing data are denoted by a period in the data set. Periods were later removed for data dissemination purposes and left blank. Data are missing due to equipment failure where no probes were deployed, maintenance/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. For the following deployments, the dataloggers were not equipped with depth sensors, therefore depth data was not collected: Site MC 11/04/2003 12:15:00; 11/13/2003 11:45:00 Site IP 04/08/2003 10:00:00; 04/15/2003 12:30:00 LINEAGE/PROCESS STEP: PROCESS DESCRIPTION: Additional Description: Entry verification Raw data were uploaded from the YSI 6600EDS data loggers to a PC, graphs were produced and data were visually examined after each deployment using the EcoWatch software. Data files were then exported from the EcoWatch format into Excel (for Windows 2000) files, where the headers, footers, and inappropriate spaces were removed. Raw data was archived, plotted and suspect data (outliers) or trends noted initially to verify accurate instrument operation for service as needed prior to redeployment. John Zimmerelli and Chris Trumbauer were responsible for these tasks. Data from each deployment was processed initially using macros in the CDMO cdmomac3.xls program. Steps in the program include procedures which allow users to automatically format column widths to the correct number of decimal places based on YSI sensor specifications. It also allows users 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 allows PC users with 30-minute data to automatically create a monthly Excel file from a two-week deployment and insert periods for missing data. Periods were later removed for data dissemination purposes and left blank. In 2004, John Zimmerelli with the help of Mark Trice at the Department of Natural Resources changed the import macro to allow PC users to import 15-minute data into this form. 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. Raw data from successive deployments were merged using the CDMO import.xls macros to produce monthly files. Resulting monthly Excel files at each site (eg. JB0302.xls) consist of continuous data for all variables measured, with a period (.) to denote any missing data. At this point, these data have not been modified except for replacement of missing entries with a period. Data were then processed using the CDMO cdmomac3.xls macros as an initial step in QA/QC procedures to identify outliers, defined simply as values outside the respective sensor specifications. Results are retained as monthly Excel files for each site (eg. JB0302outliers.xls). The final data processing involved identification and documentation of data points judged to be anomalous (suspect) or erroneous due to extreme natural events or equipment malfunctions using various procedures including recommendations from CDMO Operations Manual Appendix B, YSI 6000 Data Review and Editing Protocol. Anomalous data were retained in cases where no definite reason for deletion was found. Periods during which data were found to result from equipment malfunctions, failure, tampering or exposure to air by low tides were identified, times with causes or related observations documented below and respective data removed or deleted. These resulting edited data and documentation (metadata) were archived, formatted in comma delimited file format and submitted to the CDMO for further QA/QC. John Zimmerelli and Katie Diblasi were responsible for these tasks. PROCESS DATE: 20060208
Access Constraints
Data collected in conjunction with the National Estuarine Research Reserve System's (NERRS) System-wide Monitoring Program (SWMP) is considered public information. Please see site for further information: http://cdmo.baruch.sc.edu/aboutdata.htm LIABILITY: Distribution 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. NOAA/ERD retains the right to analyze, synthesize and publish summaries of the NERRS System-wide Monitoring Program data. The PI retains the right to be fully credited for having collected and processed the data.
