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 Three dataloggers are deployed at Mar Negro area, major component of Jobos Bay Estuarine Research Reserve, and are suspended from a pole at 0.3 meter from the bottom of the selected site. Only data from stations 9 and 10 will be submitted to the Centralized Data Management Office as part of the System-Wide Monitoring Program. Measurements are taken in thirty (30) minute ... intervals for approximately two-week periods. The sites are identified as representative of areas within the reserve and comparable to the sites that may be receiving impact from human activities in the surroundings areas. Station number nine (9), the impacted site, collects water quality data in a site associated with runoff from littoral and basin mangroves areas. This sampling station is closer to the Electric Power Thermoelectric Plant, which makes it subject to runoff and potential spills contamination from this industrial facility. Information compiled from historical environmental documents indicate that station nine (9) was used as a disposal site for the residues of the previously operating sugar mill operation, which might have been a high organic input to the sediments. Station number ten (10), located in the mangrove lagoon area is the reference or non-impacted site.
SUPPLEMENTAL INFORMATION:
Associated researchers and projects A water quality and plankton monitoring scheme was initiated in 1995, to monitor 12 stations in the Jobos Bay system. This effort, conducted by the Department of Natural and Environmental Resources Laboratory began in March 1995, using a Hydrolab Data sonde 3 with a Surveyor 3 readout system, monitoring the water column on a bimonthly time basis for abiotic parameter similar to the YSI. Monthly samples for nutrients, plankton and chlorophyll were conducted from March to October (Water Quality Monitoring-Spatial and temporal variations of main abiotic and plankton components in JOBNERR, 1996). Samplings were resumed in January 1996 and will be conducted until March 1997). Other remarks/notes Several files were lost when our hard disk crashed. In most occasions a file had information that was part of two months. Backup copies were available for most files but not all. During the following date and times, depth was recorded in feet instead of meters. Data were later converted to meters for Station 10 on the following dates: 1/22/99 16:00 – 02/16/99 09:00 04/01/99 00:00 – 04/07/99 09:00 06/01/99 00:00 – 06/02/99 09:30

SPATIAL DATA ORGANIZATION INFORMATION:
Indirect Spatial Reference: Site location and character The Jobos Bay National Estuarine Research Reserve (JOBNERR) is located on the southern coastal plain of the island of Puerto Rico, a reserve within the West Indies geographical area. JOBNERR is composed of two major areas: (1) Mar Negro, located on the western margin of the Bay, and (2) Cayos Caribe, a chain of 15 tear-shaped islets located to the southeast. The Mar Negro area comprises the bulk of the Reserve, and consists of mangrove forests and a complex system of lagoons and channels interspersed with salt and mud flats. Coral reefs and seagrass beds, with small beach deposits and upland areas fringe Cayos Caribe mangrove islands. Station 9 is an impacted site and is located at the northeastern part of the Mar Negro unit. The sampling station is associated with the mangrove lagoon area and received the Thermoelectric Power Plant runoff through mudflats and areas adjacent. The tidal range varies from 12 in. to 14 in. in the vicinity of the monitoring station. No fresh water input in the vicinity of the station is probable. The salinity at the vicinity of the monitoring station varies from 0.0 ppt to 41.1 ppt. The station pole is located at 17° 56' 36.8" N and 66° 14' 18.5" W. Station 10 is located in a mangrove lagoon not impacted from upland or marine activities. It provided a reference for comparison of the data obtained in other stations, especially to the stations in Mar Negro lagoon environment. The tidal range varies from 12 in. to 14 in. in the vicinity of the monitoring station. No fresh water input in the vicinity of the station is probable. The salinity at the vicinity of the monitoring station varies from 0.0 ppt to 41.7 ppt. The pole is located at 17° 56' 20.3" N and 66° 45' 26.7" W. Station 11 datalogger is tied to a small pier stand in the westernmost lagoon in the Mar Negro unit. Although a chain from a small pier suspends this datalogger, and it has been deployed at the same depth of the other dataloggers. Non point sources of contaminants from residences and boating activities in the vicinity are probable. The lagoon is characterized by dark bottom, tidal range from 12 in. to 14 in., allegedly related to long-term deposition of organic wastes from the sugar mill operation when the mill was operating. No fresh water input in the vicinity of the station is probable. The salinity at the vicinity of the monitoring station varies from 0.0 ppt to 36.7 ppt. The datalogger is suspended by a chain and localized at 17° 56' 41.8" N and 66° 15' 46.0" W. Data from stations 9 and 10 are the only one to be submitted to the CDMO. Of five sondes we have, two will be permanently devoted to take reading from this two sites, while other two will serve as replacement when sondes are taken out of the water for data upload and maintenance. This will avoid data gaps for station 9 and 10 between sonde maintenance procedures. Data collected by station 11 will not be submitted because of gaps that will result at sonde retrieval for data uploading and maintenance. All monitoring is considered long term.

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. : After retrieving and carefully cleaning the dataloggers, they are examined to detect any structural damage to the body or to the probes. The DO membrane is checked for ruptures and then replaced if needed. The turbidity probe is examined to assure that no obstruction affects the wiper and that the sensor is clean. Manipulation and observation are registered in the field log for each deployment respectively. The YSI is connected to a Pentium II 400 MHz IBM compatible computer and the data are reviewed using the YSI computer program Ecowatch for Windows that accompanies the YSI 6000 datalogger. The file is uploaded in two formats, one in YSI PC6000 format and the other in Comma Delimited format then the file is renamed to have a ".txt" extension. The YSI Ecowatch for Windows program is used to plot the data and delete the pre- and post deployment data that are not in range of the other readings. The program is used to perform basic statistical analysis (i.e., min., max., mean, std. dev.). Data is initially reviewed using the Ecowatch graphing tool. Data for a month is compiled into one single Excel 97 data sheet for further examination to detect gross outliers, data recorded during instrument retrieval or caused by instrument failure. Missing dates and times are checked before submitting the data to the Centralized Data Management Office. CDMO Excel macros are provided to assist in data review and data editing. Data is opened into this program and empty or unrecorded data spaces are filled with periods. Columns are formatted to have a specific size and specific number of decimal place holders as specified by the NERR CDMO. Date and time readings are also checked and outliers are identified. The outliers file is saved and printed for revision of each file. Missing data and explanatory reasons are recorded in the metadata missing data section. Data that was found to be out of the instrument range or normal parameters for each sampling station is removed from the file and a period is inserted to the cell (s). Explanation for changes in data is also included in the metadata. Data that were outside the "normal" range of water quality for a particular site is investigated for validity based on filed observation, QC check, Ecowatch for Windows printouts, and the instrument diagnostics. The metadata form is submitted with the data to the CDMO. Data is stored in zip disks. Dr. Pedro Robles, Research Coordinator, is responsible for data management. PROCESS DATE: 20060213
