Abstract:

This image represents a 1 meter resolution backscatter mosaic of the Abrir La Sierra Bank off the coast of western Puerto Rico, collected using a SeaBat Reson 8124 (200 kHz) multibeam echosounder.NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in the U.S. Caribbean from 4/14/07 to 4/24/07. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) and with a moon pool-mounted Reson 8124 multibeam echosounder (200 kHz). It was processed by a NOAA contractor using CARIS HIPS software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides from NOAA COOPS. Data is in UTM zone 19 north, datum NAD83. The backscatter component of the bathymetry data were geometrically and radiometrically corrected using Geocoder 3.0 software. Acoustic backscatter mosaics are ostensibly an important piece of information when characterizing surficial seafloor features and delineating benthic habitats.The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependent on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

Purpose:

This multibeam data was collected as IOCM (Integrated Ocean and Coastal Mapping) project NF-07-06 during the fourth year of an ongoing NOAA scientific research mission in the US Caribbean to characterize midshelf and deep water coral reef habitats at depths down to 1,000 meters. The mission purpose is to better understand the resources within the surveyed reef habitats, and ultimately develop species utilization models linking physical habitats with biological information. The multibeam backscatter, multibeam bathymetry, and ground truth video footage collected during the 2007 mission will be used internally to characterize sea floor topography and to create benthic habitat maps, helping NOAA meet its mapping commitment to the US Coral Reef Task Force. The resulting publicly-distributed data is also a contribution to the greater scientific community interested in the U.S. Caribbean seafloor.

Supplemental Information:

Depth datum is mean lower low water, units are meters and encoding method is explicit depth coordinate included with horizontal coordinates. Vertical Coordinate System information may be found in the Data Acquisition and Processing Report (DAPR) for cruise number NF-07-06.

Data Quality

Horizontal Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-07-06.

Vertical Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-07-06.

Completeness Report:

This Backscatter GeoTIFF is sourced from the original full-resolution multibeam data that was used to create a down sampled uniform-resolution backscatter grid. The down sampled grid nodes from that backscatter surface were then exported and used to generate the ESRI GeoTIFF. Some minor positional shifts may have occurred between the original data points and the transformed GeoTIFF.

Conceptual Consistency:

While the project was conducted to meet IHO Order 1 and 2 accuracy standards, dependent on project area and depth, all users should independently analyze the dataset according to their own needs and standards to determine data usability.

Process Steps

Process Step 1

CC ID: 599717
Description:

For this project, the Chief Scientist was NOAA/NOS/NCCOS/CCMA's Tim Battista and the Lead Hydrographer was independent contractor Mike Stecher. Data was collected aboard the NOAA ship Nancy Foster from 4/14/2007 to 4/24/2007, as project number NF-07-03. Multibeam data was acquired in: 1) Simrad .all format with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz); and 2) .xtf format with a moon pool-mounted Reson 8124 multibeam echosounder (200 kHz). Both MBES systems had backscatter snippet collection enabled. Line spacing for acquisition was three times the water depth (for the EM 1002) and 3.5 times the water depth (for the Reson 8124). Data was retained out to 60 degrees from nadir, depending on project area. Heave, roll, pitch and heading correctors were collected using an Applanix POS/MV Model 320 inertial measurement unit (IMU) and associated Trimble GPS antennas. Sound velocity profiles were acquired with a Seabird Electronics SeaCat SBE-911 and SBE19P CTD profilers and processed using Seabird Seaterm software. Positioning was obtained using Northstar 941X GPS receivers with differential correctors from U.S. Coast Guard CORS beacon Isabel, Puerto Rico. Data was reduced to Mean Lower-Low Water (MLLW) using final approved tides from NOAA COOPS, based on National Water Level Observation Network (NWLON) primary tide stations at Charlotte Amalie, VI (9751639) and Lime Tree Bay, VI (9751401). | Source Produced: NF-07-06 Raw Multibeam Data

Process Step 2

CC ID: 599718
Description:

Raw SWMB data were converted and processed using CARIS HIPS v6.1 software, resulting in a CARIS HDCS format dataset with all correctors applied. Attitude and SWMB data was cleaned of fliers, and SWMB data was reviewed in subset mode by a NOAA contractor. | Source Produced: NF-07-06 HDCS Processed Multibeam Data

Process Date/Time: 2007-01-01 00:00:00
Source: NF-07-06 Raw Multibeam Data

Process Step 3

CC ID: 599719
Description:

The multibeam backscatter data were corrected for geometric and radiometric distortions using Geocoder 3.0. In particular, the following corrections were applied where appropriate and when artifacts were evident: AVG Trend, TX Power and RX Gain, Area Correction, Spreading, Slant-Range and Extracted Beam Pattern. As no theoretical beam pattern for the Kongsberg Simrad 1002 system exists, it was extracted from a mapped area that was flat and had a relatively uniform (sandy) substrate. Individual lines were also truncated based on ping number and/or angle of incidence where appropriate. The final mosaics were exported as geotiffs in NAD 1983 UTM Zone 19N and Backscatter values as measured in decibels dBs. Holidays (missing data values) were filled using a nearest neighbor resampling technique. | Source Produced: BackscatterRN8124_AbrirBank_1m_2007.tif
