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 The YSI electronic data loggers are programmed to measure the water temperature, specific conductivity, dissolved oxygen, depth, pH, and turbidity conditions at 15-minute intervals. There are four permanent data logger sites at two locations in Kachemak Bay. One site is located on the northeast side of the Bay at the end of the Homer Spit, and the other on the southwest side of ... the Bay in Seldovia. At each site a data logger is suspended 1-meter below the surface, and one data logger 1-meter from the bottom. The deep site is in the same location as the previous Homer Dolphin site. The Seldovia Deep site is at the previous Seldovia site. At both locations the surface sondes are horizontally within a couple meters of the deep sondes. The circulation in Kachemak Bay is driven primarily by the 8-meter tidal flux. Regional circulation is characterized by generally cyclonic ocean currents in the Gulf of Alaska flowing onto the shelf off Cook Inlet. Nutrient rich bottom water is upwelled and mixed with surface water. These enriched waters may enter into Kachemak Bay, the inflow tending to stay along the southern shore flowing past the Seldovia instruments, while water flowing out of the bay stays along the Inner Bay and north shore, flowing past the Homer instruments. These trapped coastal flows separate the bay into two distinct ecosystems, and the instruments are positioned to reflect this distinction. Within each system there is vertical stratification of the water. The vertical placement of the sondes is designed to help elucidate the differences in circulation of the surface and deep waters. As the inflowing water proceeds up the bay, fresh water runoff from the surrounding ice fields and watersheds dilute the salinity and increase the sediment load in the path of the Homer instruments. The inflowing water, in the path of the Seldovia instruments initially supports a marine system, while the north out flowing water of the Homer instruments, is more estuarine. The Kachemak Bay water quality instruments capture this difference with deployments along the north and south shores. These data will be used to supplement studies on primary productivity, larval distribution, settlement, recruitment, growth rates, community dynamics, and biodiversity in the bay.

ATTRIBUTE ACCURACY REPORT: Anomalous/Suspect Data Note: Outliers in the data are defined to be any point greater than 4 standard deviations from the mean of the 24-hour period surrounding that point. Turbidity outliers are most commonly related to fish and invertebrates within the sonde guard. The turbidity outliers were deleted and are marked in section 12. Note: Between sonde rotations we ... typically encounter the following jumps in data as a result of calibration offsets and probe accuracy: pH: +/- 0.02 DO %: +/- 10 DO Conc: +/- 1 mg/l January 1-31, 2004 Note: Outliers in the data are defined to be any point greater than 4 standard deviations from the mean of the 24-hour period surrounding that point.

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. For the Homer and Seldovia sites, the 15-minute data are uploaded to the PC from both the YSI Model 6200 Data Acquisition System via modem at 60-minute intervals, and the YSI 6600 Sonde Data Logger upon recovery. The text files are initially viewed with Ecowatch software, and graphs are produced to look for suspect data as may result from probe failure. Notes are made of any unusual data, and sensors are reconditioned as necessary. The text data files are run through a Matlab routine created by Scott Pegau for processing. This routine is attached at the end of this report. The routine is set to output data every 15 minutes to match data collection intervals. The routine looks for data collected within 7.5 minutes of the desired output time. Data that were recorded when the instruments were out of the water are deleted from the beginning and end of each record. These data are identified by unusual depth and salinity data (usually near zero). The routine outputs a data file listing the missing data points, fills all cells that do not contain data with blanks, and finds and removes all data points that fall outside the range of what the data logger is designed to measure, or are out of realistic ranges for Kachemak Bay. The routine then processes the data through several filters to flag suspect data points that are greater than 4 standard deviations from data gathered in the 24-hour period surrounding the point. It can remove the data point or just flag it as suspicious. In addition, a graphing capability is included to produce single and multi-parameter graphs on a monthly or yearly basis. The routine outputs monthly files with column widths formatted to the correct number of decimal places based on YSI sensor specifications. Anomalous data are evaluated to determine whether to flag or delete the suspect values. Data are flagged if they fall outside the normal values seen at the site, or outside the range of measurements and accuracy established for the sensors. Data outside the "normal" range of water quality for a particular site were investigated for validity based on weather data, field observations, QC checks, and instrument diagnostics. Data are deleted if anomalies are attributed to sensor malfunction or fouling of the sensors by aquatic organisms, debris, or sediment. In addition, sensor readings that differ significantly (>10%) from calibration standards suggest that the sensor was fouled during deployment. After corrections are made to the text files, and anomalies noted in the metadata report, the edited files are exported as tab delimited (*.txt). The monthly text files are then combined to produce the yearly data file that is sent to the CDMO. Raw (*.csv) files are also sent to the CDMO for archival. Scott Pegau is responsible for these tasks. PROCESS DATE: 20060214
