Description:
Abstract:
The Loxahatchee River and estuary is a small (544 square miles), shallow, water body located in Southeastern Florida that empties into the Atlantic Ocean at Jupiter Inlet. The watershed drains an area of over 200 square miles within northern Palm Beach and southern Martin counties. Historically this system was primarily fresh-water; however, tidal flows opened the inlet for some of the time. In 1947, the inlet was dredged for navigation and has remained permanently open since that time. Drainage patterns within the basin have been significantly altered due to drainage and development, road construction (e.g., Florida Turnpike, BeeLine Highway), and construction of the C-18 canal to provide flood protection for residential areas.
The St. Lucie Estuary (SLE) and its watershed are located on the Southeast coast of Florida in Martin and St. Lucie counties. The SLE watershed encompasses about 781 square miles and is divided into five major basins, which discharge into the Indian River Lagoon and the Atlantic Ocean through the St. Lucie Inlet. The St. Lucie Canal (C-44), along with the Caloosahatchee River (C-43) are important components of the Central and Southern Florida Project and are primarily used for water releases from Lake Okeechobee when lake levels exceed established regulatory requirements of the United States Army Corps of Engineers. The C-44 Basin is particularly dependent on the lake for supplemental water supply and aquifer recharge.
This report serves as an archive of processed single-beam bathymetry data that were collected in Loxahatcheee and St. Lucie Rivers, Florida in 2003. Geographic information system data products include a XYZ data, bathymetric contours, and USGS quadrangle map. Additional files include formal Federal Geographic Data Committee metadata.
Purpose:
This project addresses the collection and interpretation of data necessary to develop the present day bathymetry of the Loxahatchee River, and St. Lucie River regions. This project supports several SFWMD efforts including the proposed MFL development for the Loxahatchee and St. Lucie River MFLs and the Indian River Lagoon Feasibility Study. All of these state-mandated efforts would utilize data obtained from these surveys to develop hydrodynamic models, which are essential in understanding the ecological processes of each of these coastal systems. This project also supports other non-modeling efforts such as the determination of the oligohaline zones in the St. Lucie River systems.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The accuracy of the data is determined during data collection. This dataset is derived from a single research cruise using identical equipment, set-ups, and staff; therefore, it is internally consistent. Methods are employed to maintain data collection consistency aboard the platform. During mobilization, each piece of equipment is isolated to obtain internal and external offset measurements with respect to the survey platform. All the critical measurements are recorded manually and digitally entered into their respective programs. Offsets between the single-beam transducers and the Ashtech antenna reference point (ARP) were measured and accounted for in post-processing. Bar checks were performed as calibration efforts and accounted for any drift in the Marimatech Echosounder. Differential Geographic Positioning System (DGPS) coordinates were obtained using post-processing software packages developed by the National Oceanic and Atmospheric Administration (NOAA)/National Geodetic Survey (NGS) Online Positioning User Service (OPUS), National Aeronautics and Space Administration (NASA)/Jet Propulsion Laboratory (JPL) Online Positioning User Service (GIPSY), and Scripps Orbit and Permanent Array Center Online Positioning User Service (SCOUT). Boat trajectories were computed with PNAV v2.0 software by ASHTECH, Inc. These bathymetric data have not been independently verified for accuracy.

Horizontal_Positional_Accuracy_Report:
The GPS antenna and receiver acquisition configuration used at the reference station was duplicated on the survey vessel (rover). The base receiver and the rover receiver record their positions concurrently at 1Hz recording intervals throughout the survey. All processed measurements are referenced to the base station coordinates.
GPS base or differential reference stations were operated within approximately 15 to 20 km of the survey area. Two new temporary ground-control points or benchmarks (surveyed to within 1 cm to 2 cm accuracy) were established throughout the study area for use as reference receiver sites using standard benchmarks procedures. The new benchmarks were surveyed using Ashtech Z-12, 12 channel dual-frequency GPS receivers. Full-phase carrier data were recorded on each occupied benchmark in Ashtech proprietary BIN format with daily occupations ranging from 6 to 12 hours. BIN files were then converted to RINEX-2 format for position processing.
All static base station GPS sessions were submitted for processing to the online OPUS, GIPSY, and SCOUT system software. The computed base location results were entered into a spreadsheet to compute one final positional coordinate and error analysis for that base location. The final positional coordinate (latitude, longitude, and ellipsoid height) is the weighted average of all GPS sessions. For each GPS session, the weighted average was calculated from the total session time in seconds; therefore, longer GPS occupation times held more value than shorter occupation times. Results were computed relative to ITRF00 coordinate system. The established geodetic reference frame for the project was WGS84. Therefore, final reference coordinates used to process the rover data were transformed from ITRF00 to WGS84 using National Oceanic and Atmospheric Administration/National Geodetic Survey(NOAA/NGS) HTDP software v2.1.
OPUS, GIPSY, and SCOUT results provide an error measurement for each daily solution. Applying these error measurements, the horizontal accuracy of the base station is estimated to be 0.04 (m) root mean squared (RMS).
The kinematic (rover) trajectories were processed using PNAV v2.0, by ASHTECH, Inc. A horizontal error measurement, RMS is computed for each epoch. The horizontal trajectory errors for varied between 0 and 0.08(m).
The combined horizontal error from base station coordinate solutions and rover trajectories range from 0 and 0.12 (m), with the average approximately 0.06 (m).

Process_Description:
Data Acquisition - The sea-floor of the Loxahatcheee and St. Lucie Rivers was mapped by using an outboard motor boat, equipped with a high-precision Global Positioning Systems (GPS) coupled with a high-precision depth sounder. To accomplish this task, the SANDS (System for Accurate Nearshore Depth Surveying) system was developed by Mark Hansen (SPCMSC) and Jeff List (WHSC) of the U.S. Geological Survey. SANDS consists of two components, hardware and processing techniques.
Survey track lines spacing were spaced 500-meters apart and orientated in a north/south orientation. Track lines collected parallel to the lake shoreline (intersecting track lines) functioned to serve as a cross-check and to assess the relative vertical accuracy of the survey. Crossing lines are critical because they serve as a check on the internal accuracy of the data. Soundings were collected along each track line at 3 m spacing. In shallow areas, data were collected in a minimum of 0.3 m water depth except where there was potential damage to the bottom environment or the boat/motors.
Reference GPS reference stations were operated on an USGS benchmark bench mark, typically located within approximately 15 km of the farthest single-beam track line. Reference and rover GPS receivers recorded the 12-channel full-carrier-phase positioning signals (L1/L2) from satellites via ASHTECH choke-ring antennas. The reference and rover receivers record their positions concurrently at 1-second(s) recording intervals throughout the survey.
Boat motion was recorded at 50-millisecond (ms) intervals using a TSS Dynamic Motion Sensor 05 (TSS DMS-05). Bathymetric soundings were recorded at 10-ms intervals using a Marimatech EC-100 survey grade echo-sounder. The single-beam data were acquired using the hydrographic software HYPACK version 5. All data strings from the instruments were streamed in real time and recorded through HYPACK software.

Process_Description:
Differentially Corrected Navigation Processing- The coordinate values of the reference GPS base stations obtained from OPUS were provided in the ITRF00 coordinate system. All survey data for the project was referenced to WGS84. Consequently, reference station coordinates were transformed to WGS84 coordinates using the NOAA/NGS software HTDP v1.3. The respective reference (base) station coordinates utilized as reference positions were imported into PNAV v2.0 software by ASHTECH, Inc. Differentially corrected rover trajectories were computed by merging the master and rover the GPS data. During processing, steps were taken to ensure that the trajectories between the base and rover were clean, resulting in fixed positions. By analyzing the graphs, trajectory maps, and processing logs that GrafNav produces for each GPS session, GPS data from satellites flagged by the program as having poor health or satellite time segments that had cycle slips could be excluded, or the satellite elevation mask angle could be adjusted to improve the position solutions. The final differentially corrected precise DGPS positions were computed for each rover GPS session and exported in ASCII text format.

Process_Description:
Single-beam Bathymetry Processing- All data were processed using SANDS version 1.2. The primary purpose of SANDS is to time synchronize processed trajectories, soundings, and heave/pitch/roll, then merge all data strings. SANDS applies latency errors, applies geometric corrections for antenna staff pitch and roll, applies geometric corrections for antenna transducer pitch and roll (beam correction), time synchronizes the GPS trajectory and HYPACK files for each GPS epoch, and converts WGS84 latitude/longitude coordinates to North American Datum of 1983 NAD83/GRS80 UTM coordinates (m), and applies a geoid separation based upon NOAA/NGS the Geoid99 model. Latitude/longitude conversion to UTM coordinates was accomplished using NOAA/NGS UTM v2.0 software. Intermediate output files are comma delimited text files containing: time of day (seconds of day), UTM X coordinate (m), UTM Y coordinate (m), ellipsoid height, orthometric height, smoothed raw depths, PNAV RMS value, and HYPACK line number. A header line indicates the attributes entry for each column.
