Title: NOAA ESRI Geotiff- 2m Multibeam Backscatter of NPS's Salt River Bay National Historical Park and Ecological Reserve, St. Croix, US Virgin Islands, Project NF-05-05, 2005, UTM 20 NAD83
Short Name: NF05_USVI_SaltRiverSTX_Backscatter_1m_Metadata
Status: Completed
Publication Date: 2006-03
Abstract:

This image represents a 2 meter resolution backscatter mosaic of the north shore (Salt River) of St. Croix, US Virgin Islands. 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 US Virgin Islands from 2/1/05 to 2/12/05. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA contractor using CARIS HIPS v5.4 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 20 north, datum WGS84. The backscatter component of the bathymetry data were geometrically and radiometrically corrected using Geocoder 2.8 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, dependant 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-05-05 during the second year of an ongoing NOAA scientific research mission in the US Caribbean to characterize nearshore coral reef habitats at depths down to 300 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 2005 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 USVI seafloor.

Data Quality

Horizontal Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-05-05.

Vertical Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-05-05.

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, dependant 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: 599641
Description:

For this project, the Chief Scientist was NOAA/NOS/NCCOS/CCMA's Tim Battista and the Lead Hydrographer was independent contractor Jay Lazar. Data was collected aboard the NOAA ship Nancy Foster from 2/1/05 to 2/12/05, as project number NF-05-05-VI. Multibeam data was acquired in GSF format with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz), with options 033, 037, and 040. Reson backscatter snippet collection was enabled. SAIC ISS 2000 software was used to interface with the Reson system. Line spacing for acquisition was three times the water depth, and data was retained out to 60 or 70 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 SBE19P CTD profiler and processed using Seabird Seaterm software, then applied directly to the raw GSF data. 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-04-06 XTF Raw Multibeam Data

Process Step 2

CC ID: 599642
Description:

Raw SWMB data in GSF (generic sensor format) format were converted and processed using CARIS HIPS v5.4 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. Process Date Range is 200502 - 200511

Process Date/Time: 2005-11-01 00:00:00
Source: NF-05-05 HDCS Processed Multibeam Data

Process Step 3

CC ID: 599643
Description:

The contractor used CARIS HIPS v5.4 to evaluate each line for bottom tracking and to perform slant-range corrections. Data was not corrected for gain or transmit power artifacts. After this cursory processing, the data was mosaiced together using the shine-through backscatter option. The resulting backscatter mosaic was then exported as a Geotiff. | Source Produced: NF04_STX_BuckIS_Backscatter_.5m.tif
