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:
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.

Quality
ATTRIBUTE ACCURACY REPORT: Anomalous/Suspect Data Any data outliers detected using CDMO
macros and any data deletions are detailed below. Suspect and outlier data were detected and
considered for deletion from the edited data using combination of methods, including ECOWATCH
graphical software and CDMO macros. All outliers are ... detailed below. Any data determined to be
due to instrument errors or malfunctions were retained in raw data. Missing data and any
intended deletions from edited data were replaced with a period (.) in accordance with CDMO
QA/QC guidelines and detailed below. According to the CDMO Operations Manual Version 4.0, depth
measurements taken with the non-vented level probe can be influenced by up to 0.39 m (1.3 ft)
during some low-pressure hurricane events. Specific dates and time ranges of potentially
influenced data are listed with each respective month. Railroad Bridge Sonde deployment at RR

06/02/2003 21:30:00 06/03/2003 06:15:00 Erratic Turbidity data removed, wiper may be blocking
optic sensor. 06/14/2003 18:45:00 - 06/17/2003 08:15:00 July 2003 Turbidity spike deleted due to
transient material blocking optic. 07/11/2003 20:45:00 August 2003 The following reading was
taken with the check sonde, "Cindy." The deployed meter was out of the water for data retrieval.
There is no depth reading for this data point because the check sonde does not have a depth
sensor. 08/19/2003 08:45:00 September 2003 Turbidity spikes deleted due to transient material
blocking optic. 09/07/2003 16:45:00 October 2003 The following reading was logged by the check
sonde, "Ophelia." The deployed sonde was out of the water for data retrieval. There is no depth
reading for this data point because the check sonde does not have a depth sensor. 10/01/2003
08:30:00 The pH read 0.25 units high on post-cal on 10/08, and read high by 0.45 units on the
10/9 in-situ match-up with Hydrolab instrument. Consider pH for this deployment as suspect.
10/01/2003 08:15:00 - 10/07/2003 08:30:00. The following readings were logged by the check
sonde, "Babs." The deployed sonde was out of the water for data retrieval. There is no depth
reading for these data points because the check sonde does not have a depth sensor. 10/14/2003
08:15:00 - 08:30:00 The pH in situ matchup on 10/28/2003 is off by 0.4 units from "check" meter
and off 0.3 from Hydrolab. Deleted pH data for entire deployment. 10/22/2003 09:00:00 -
10/28/2003 09:30:00 The following readings were logged with check meter "Babs." The deployed
meter was out of the water for data retrieval. However, the readings are inconsistent with the
rest of the data set and were deleted. 10/28/2003 09:45:00 - 10:00:00 November 2003 DO
post-calibration and in-situ matchup reading low by more than 1.0 mg/l. All DO data deleted for
this deployment. 11/04/2003 10:30:00 - 11/13/2003 09:30:00 December 2003 Turbidity spikes
deleted due to transient material blocking optic. 12/27/2003 14:00:00 MATAPONI CREEK Sonde
deployment at MC began 4/22/03 at 09:30:00. April 2003 Instrument out of water for following
periods due to extreme low tide. 04/23/2003 16:00:00 - 04/23/2003 19:00:00 04/24/2003 04:45:00 -
04/24/2003 06:00:00 04/24/2003 17:00:00 - 04/24/2003 19:00:00 04/28/2003 21:30:00 - 04/28/2003
22:00:00 04/29/2003 21:45:00 - 04/29/2003 23:30:00 Turbidity spikes deleted due to transient
material blocking optic. 04/23/2003 16:30:00 04/23/2003 18:45:00 May 2003 Negative depths
retained in data set for month of May because salinity showed meter to be in water, possibly
changes in pressure caused negative readings. (Depth Not Vented) DO probe malfunction at 09:15
on 5/6. Deleted DO data after this date. 5/6/2003 9:15:00 - 5/6/2003 12:45:00 Sonde logged no
data due to software error (version "pre-2.20.") 5/6/2003 13:00:00 - 5/13/2003 11:00:00
Instrument out of water for following periods due to low water. 5/13/2003 18:30:00 - 5/13/2003
22:15:00 5/14/2003 8:30:00 - 5/14/2003 11:00:00 5/14/2003 20:45:00 - 5/14/2003 22:30:00
Turbidity spikes deleted due to transient material blocking optic. 5/26/2003 09:15:00 June 2003
Negative depths retained in data set for month of June because salinity showed meter to be in
water, possibly changes in pressure caused negative readings. (Depth Not Vented) Meter was out
of water for period of time due to extreme low tide 6/1/2003 22:00:00 - 6/2/2003 1:00:00
Turbidity spikes deleted due to transient material blocking optic. 6/14/2003 0:15:00 July 2003
Negative depths retained in data set for month of June because salinity showed meter to be in
water, possibly changes in pressure caused negative readings. (Depth Not Vented) August 2003
Following record taken from check meter, check meter does not have depth sensor. 8/12/2003
11:15:00 pH outlier removed 8/12/2003 11:15:00 September 2003 Instrument appears to be out of
water during following interval 9/18/2003 08:45:00 - 9/18/2003 22:30:00 Anomalous DO spike in
data on 09/02/2003 14:30:00 was deleted. 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. (Depth Not Vented) December 2003 Negative depths retained in data set
for month of December because salinity showed meter to be in water, possibly changes in pressure
caused negative readings. (Depth Not Vented) Turbidity spikes deleted due to transient material
blocking optic. 12/2/2003 20:00:00 - 20:15:00 12/17/2003 20:30:01 turbidity post-cal was reading
low by >10% - data deleted. 12/11/2003 12:30:00 - 12/23/2003 8:00:00 IRON POT LANDING
Sonde deployment at IP began 4/4/03 at 14:00:00. 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. Sonde not set to log. 11/13/2003 11:00:00 - 11:15:00

12/23/03 12:30:00 Meter pulled for ice and lack of depth. 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. Following academic courtesy
standards, the PI and NERR site where the data were collected will be contacted and fully
acknowledged in any subsequent publications in which any part of the data are used. Manuscripts
resulting from this NOAA/OCRM supported research that are produced for publication in open
literature, including refereed scientific journals, will acknowledge that the research was
conducted under an award from the Estuarine Reserves Division, Office of Ocean and Coastal
Resource Management, National Ocean Service, National Oceanic and Atmospheric Administration.
