Mark Hansen Eduardo Patino 2006 text files http://sofia.usgs.gov/projects/index.php?project_url=hires_bathy The plan to acquire bathymetric data for the Caloosahatchee Estuary and Estero Bay areas was to employ two methods which have been developed by the U. S. Geological Survey (USGS) and National Aeronautical and Space Administration (NASA). The USGS method is an acoustic based system named System for Accurate Nearshore Depth Surveys (SANDS), and the NASA method is an airborne LIDAR system named Experimental Advanced Airborne Research Lidar (EAARL). The plan was to use the EAARL system to map shallow (less than 1.5 secchi depth) and non-turbid areas in Estero Bay and nearshore areas. The SANDS system was used in deeper areas and those which are turbid which includes the Caloosahatchee River. Hydrological data (stage, discharge, salinity, and water temperature) were collected in 2004-2005 on the southwest Florida coast High resolution, GPS based bathymetric surveying is a proven method to map river, lake, and ocean floor elevations. Of primary interest to the South Florida Water Management District (SFWMD) is the quantification of the present day bathymetry of Caloosahatchee Estuary and Estero Bay regions. This information can be used by water management decision-makers to develop of Minimum Flows and Levels (MFL) and better preserve fragile habitats. The areas in and around the Caloosahatchee Estuary and Estero Bay Watershed have undergone dramatic increases in the rate of residential and commercial development as well as population growth during the past 15 years. As a result, a series of initiatives were proposed to balance development and environmental interests in the region. Several initiatives including the development MFL and the Southwest Florida Feasibility Study (SWFFS) necessitated the development of hydrodynamic models of coastal waters in the Caloosahatchee Estuary and Estero Bay areas. One of the important data requirements for these models was the bathymetry. The information available at this time was dated (the last complete bathymetric survey is over 100 years old) and needed to be upgraded with a new survey. In addition, recommendations of the Estero Bay and Watershed Assessment completed in November of 1999 recommended the development of a Bay hydrodynamic and water quality model. Updated river, bay, and coastal bathymetry was required for these efforts. The area for bathymetry collection and interpretation includeed Estero Bay, Charlotte Harbor, Pine Island Sound, offshore regions of Sanibel and Captive Islands, and the Caloosahatchee and St. Lucie Rivers. In addition, a need for an Estero Bay and Charlotte Harbor estuarine mixing model was been identified by the Southwest Florida Regional Restoration Coordination Team and the Southwest Florida Feasibility Study. In order to create an accurate numerical model, current bathymetric data had to be obtained. Bathymetry data was also needed for the creation of a seagrass vision maps (a National Estuary Program (NEP) effort) and to populate the species response models created as assessment tools for several restoration programs. 20021001 20050930 ground condition Complete None planned -82.125 -81.625 26.875 25.75 none bathymetry mapping SANDS EAARL Experimental Advanced Airborne Research Lidar System for Accurate Nearshore Depth Surveying LIDAR stage discharge salinity temperature chemistry hydrology ISO 19115 Topic Category environment inlandWaters imageryBaseMapsEarthCover 007 012 010 Department of Commerce, 1995, Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions, Federal Information Processing Standard (FIPS) 10-4, Washington, D.C., National Institute of Standards and Technology United States US U.S. Department of Commerce, 1987, Codes for the identification of the States, the District of Columbia and the outlying areas of the United States, and associated areas (Federal Information Processing Standard 5-2): Washington, D.

St. Petersburg FL 33701 USA 727 803-8747 x 3036 727 803-2030 mhansen@usgs.gov This project was worked in conjunction with the South Florida Water Management District (SFWMD). Project personnel included Ruth Costley, Lars Soderqvist, Craig Thompson, and Jeff Woods ASCII text files The hydrological data from Palm River were estimated for the entire period because the index velocity meter came out of the water during low tide causing large amounts of the data to be deleted. The hydrological data were recorded every fifteen minutes for each collection site Precise differential GPS receivers are used to measure boat position and dynamic elevation, a survey quality 200 kHz depth sounder acquires water depth measurements, and a motion sensor measures heave, pitch, and roll of the boat. A measurement is collected about every 3m along a survey line. The horizontal positional accuracy of the system is +/- 4cm. Precise differential GPS receivers are used to measure boat position and dynamic elevation. The vertical accuracy of the system is +/- 8cm. The plan to acquire bathymetric data for the area was to employ methods which were developed by the U. S. Geological Survey (USGS) and National Aeronautical and Space Administration (NASA). The USGS method is an acoustic based system named System for Accurate Nearshore Depth Surveys (SANDS), and the NASA method is an airborne LIDAR system named Experimental Advanced Airborne Research Lidar (EAARL). The USGS has developed a hydrographic survey system specifically designed to map in very shallow water. The system can acquire data in water depths of approximately 25cm, but in practice boat/motor draft limitations prevent surveying in water depths less than 45cm. EAARL is a new airborne lidar that provides unprecedented capabilities to bays, the nearshore shoreface, benthic habitats, coastal vegetation, and sandy beaches. The EAARL sensor suite includes a raster-scanning-water penetrating full-waveform adaptive lidar, a down-looking color digital camera, a hyperspectral scanner, and an array of precision kinematic GPS receivers which provide for sub-meter geo-referencing of each laser and hyper-spectral sample. EAARL has the unique real-time capability to detect, capture, and automatically adapt to each laser return backscatter over a large signal dynamic range and keyed to considerable variations in vertical complexity of the surface target. EAARL limited to water depths greater than 50 cm and can penetrate the water column to approximately 1.5 secchi disk depth. The lidar has a ground footprint of 30cm with vertical and horizontal accuracies equal to the SANDS system. The swath width is 250m which converts to a spatial coverage of approximately 1 laser shot per square meter. The project would use the EAARL system to map shallow (less than 1.5 secchi depth) and non-turbid areas in Estero Bay and nearshore areas. The SANDS system would be used in deeper areas and those which are turbid which include the Caloosahatchee River. Work planned for FY 2003-2004 includes: 1. High resolution bathymetric surveying. 2. Post processing of the benchmark and hydrographic data. 3. Storage and maintenance all data and access to this data for reproduction as needed by the SFWMD. 4. A final data package to include: a. Hard copy plot of locations of surveyed areas. B. Digital ASCII XYZ data in UTM Zone17, GRS80/NAD83 horizontal coordinates, and NAVD88 vertical coordinates in tabular format. The SFWMD has also asked for the data to be projected into State Plane Coordinates, Florida East Zone (ft) NAD 83, and vertical datum National Geodetic Vertical Datum of 1929 (ft). C.

The information collected included time-series data for water level, velocity, salinity, and temperature, for a period not to exceed 3-months. Acoustic Doppler Velocity Meters (ADVM) equipped with an up-looking transducer were installed to facilitate the collection of water stage and velocity with one single instrument. ADCP discharge measurements were made for the development of Index-Velocity calibration ratings at all instrumented sites. ADCP measurement sessions thru tide were made to capture the tidal characteristics of these rivers, and used for rating development. Discharge was computed for the 3-month period for all stations, and analyzed to describe tidal magnitudes that include possible variations due to meteorological events, such as rain and wind. Priorities for bathymetric and hydrologic information needs were set by the comparison of these tidal magnitudes at all measured rivers. In turn, hydrodynamic modelers used these data to calibrate and verify models describing flow patterns throughout the study area. The study area encompassed the estuarine regions from Everglades City to Goodland. The data collection component of this task has been completed and instrumentation removed. Data analysis and report preparation are underway. 2006 Eduardo Patino U.S. Geological Survey Hydrologist mailing and physical address
