Abstract:
This image represents a 4x4 meter resolution bathymetric surface for Jobos Bay, Puerto Rico (in NAD83 UTM 19 North). The depth values are in meters referenced to the NAD83 ellipsoidal heights.

NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA's Chesapeake Bay Office and other territory and federal partners, acquired interferometric backscatter and bathymetry data in Puerto Rico from 04/07/2009 to 04/21/2009. Data were acquired with a pole-mounted Teledyne Benthos C3D-LPM interferometric SoNAR (200 kHz) and processed using CARIS HIPS and SIPS v7.0 software. The backscatter data were geometrically and radiometrically corrected using the Geocoder module in Hypack 2009. Acoustic backscatter mosaics are an important piece of information when characterizing surficial seafloor features and delineating benthic habitats.

Purpose:
This acoustic dataset was collected to support the characterization of seafloor features in, and creation of a benthic habitat map for, the Jobos Bay National Estuarine Research Reserve (NERR) in Puerto Rico. The benthic habitat map was created in order to support the management needs of the Jobos Bay NERR site, as well as to support the U.S. Department of Agriculture's Conservation Effects Assessment Project (CEAP) in Puerto Rico. The resulting publicly-distributed data is also a contribution to the greater scientific community interested in seafloor mapping in Puerto Rico.

Process_Step:
Process_Description:
The Lead Hydrographer for this mapping project was independent contractor Jay Lazar from NOAA's Chesapeake Bay Office. Bathymetric and backscatter data were collected aboard the R/V Jurel from 4/7/2009 to 4/21/2009 using a pole-mounted Teledyne Benthos C3D-LPM interferometric (200 kHz) sonar. These datasets were logged in .HSX format using Hypack 2009. Line spacing for acquisition was typically three to five times the water depth, providing 100% bottom coverage. Heave, roll, pitch and heading correctors were collected using an Ixsea Octans gyrocompass and integrated motion sensor. Sound velocity profiles were acquired with a hand held CTD (conductivity, temperature and depth) profiler. Horizontal and vertical positions were obtained using a Trimble DSM 232 GPS receiver.
Process_Date: 2009
Process_Step:
Process_Description:
GraphNav software was used to calculate vertical ellipsoidal heights and differentially correct horizontal positions using the CORS (Continually Operating Reference Station) in Coamo, Puerto Rico. This PPK (post processed kinetic) data was collected to tidally correct surveyed depths.
Process_Date: 2009
Process_Step:
Process_Description:
Post mission, it was discovered that the sound velocity values in the raw HSX files needed to be replaced with the sound velocity value at the sonar head. The SV values in the HSX file needed to be replaced because the acquisition software packages (i.e., Hypack and C3D Benthos) did not transfer these values from the sonar head to the HSX datagrams correctly. An example of the incorrect SV value (i.e., 1500.00) in the HSX RMB header is show below:

RMB 1 41815.565 2 4 1881 200 1500.00 18490

The correct sound velocity values at the sonar head were located in the “look up” server log text file for each day. An example of a server log is shown below:

Tue Apr 07 15:53:40 2009:Ping# 48889 S/ch 1902 Rng(m)49.9 Lty 592.017889 SpeedSound=1540.562256 Tue Apr 07 15:53:40 2009:Ping# 48890 S/ch 1902 Rng(m)49.9 Lty 650.454044 SpeedSound=1540.562256 Tue Apr 07 15:53:40 2009:Ping# 48891 S/ch 1902 Rng(m)49.9 Lty 599.314928 SpeedSound=1540.562256

The SV values in the server log, however, were 1 m/s too slow (due to a calibration issue). Consequently, a value of 1 m/s was added to each SV value in the server log files before they were used to replace the SV values in the HSX files (using a custom script built by NOAA's Biogeography Branch). In all, SV values in 662 HSX lines were replaced using SV values from 12 separate server log files. These adjusted lines were then imported into CARIS v7.0.

Process_Description:
A geoid model was created for Jobos Bay in order to convert the surveyed depths from NAD83 ellipsoid heights and to Geoid03 heights. It is important to point out that GEOID03 heights are always above NAD83 ellipsoid heights. In order to convert from ellipsoid to geoid heights, the GEOID03 interpolation program (intg.exe) and binary grid file (g2003p01.bin) for Puerto Rico and the Virgin Islands (15 - 21 N & 291 - 296 E) were downloaded from NOAA's National Geodetic Survey (<http://www.ngs.noaa.gov/PC_PROD/GEOID03/>). In ArcGIS, a uniform 1x1 km point grid was created cover the entire surveyed area in Jobos Bay. Latitudes and longitudes were computed for each point in the 1x1 km grid. This point file was converted to a XYZ text file, and imported into the GEOID03 interpolation program. GEOID03 heights were calculated for each XY location, and added to the existing XYZ text file. This XYZ text file was imported into CARIS v7.0, and used as the model file to compute GPS tides. Dynamic heave and waterline offsets were also applied to the computed model. Once the model was computed for each line, the ellipsoidally referenced heights (from GraphNav) were reformatted to CARIS HIPS tide (.tid) files, and applied to the CARIS HDCS lines based on Julian day.
Process_Date: 2009
Process_Step:
Process_Description:
Bathymetric data in HSX format were converted to HDCS format using CARIS HIPS v7.0 software. Zero tides and sound velocity corrections were applied to the converted lines. These corrections were then merged and used to calculated total propagated uncertainty (TPU). Zero tides were applied because the application of GPS tides created soundings above the water line and up to +/- 2m vertical stair-step-like artifacts between adjacent lines. Given that the application of GPS tides introduced more vertical error than they resolved, the depths for Jobos Bay were left being referenced to NAD83 ellipsoid heights (and not to Geoid03 heights).
Process_Date: 2009
Process_Step:
Process_Description:
CARIS HIPS v7.0 software was used to generate a BASE surface (Bathymetry Associated with Statistical Error) from the processed HDCS data. The BASE surface was created using CUBE (Combined Uncertainty and Bathymetry Estimator) with the following parameters: (1) IHO S-44 Special Order specifications, (2) density & locale diambiguation method and (3) 0 - 100 m depth filter. The final BASE surface was created at a 4x4 m spatial resolution. Additional fliers were manually rejected in subset editor, in order to mitigate artifacts that were not removed by CUBE. Once the surface was satisfactorily cleaned, existing data holidays were filled using interpolation in CARIS (parameters = 1 iteration, matrix size of 5, 10 neighbors). The final, interpolated surface was exported to a comma delimited ASCII XYZ file using the "BASE Surface to ASCII" tool.
Process_Date: 2009
Process_Step:
Process_Description:
Using a custom tool, the ASCII XYZ file was converted to a GeoTIFF in ArcMap. The custom tool was called "Convert XYZ to Raster" and is freely available for download from ESRI online support (www.support.esri.com).
