Title: NOAA ESRI Geotiff - 3m Backscatter Mosaic, Puerto Rico (Isla de Vieques) - UTM 20N NAD83
Short Name: NF08_PR_Vieques_Backscatter_3m_Metadata
Status: Completed
Publication Date: 2011-01
Abstract:

This image represents a 3 meter resolution backscatter mosaic of selected portions of seafloor around Isla de Vieques, Puerto Rico. NOAA's NOS/NCCOS/CCFHR, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in Puerto Rico from 3/27/08 to 4/5/08. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 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 and zoning from NOAA COOPS. Data is in UTM zone 20 north, datum NAD83. The backscatter component of the bathymetry data was geometrically and radiometrically corrected using Geocoder 3.2.1 software. Acoustic backscatter mosaics are 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 by CCFHR during the fifth year of an ongoing NOAA scientific research mission in the US Caribbean to characterize nearshore to 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 2008 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 Puerto Rican seafloor.

Data Quality

Horizontal Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-08-04.

Vertical Positional Accuracy:

See Data Acquisition and Processing Report (DAPR) for NF-08-04.

Completeness Report:

This ESRI Geotiff is sourced from a gridded dataset. The original full-resolution multibeam data was used to create a downsampled uniform-resolution CARIS BASE (Bathymetry Associated with Statistical Error) surface grid with a best depth component. The downsampled grid nodes from that depth surface were then exported and used to generate the ESRI Geotiff. Some positional shifts may have occurred between the original data points and the transformed grid.

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: 599917
Description:

Data was collected aboard the NOAA ship Nancy Foster from 3/27/08 to 4/05/08. Multibeam data for 2008 were acquired in .all format with a hull-mounted Kongsberg Simrad 1002 ER multibeam echosounder (95 kHz). Backscatter snippet collection was enabled. Line spacing for acquisition was three times the water depth, and data was retained out to 55 degrees from nadir for areas deeper than 55 meters and 60 degrees from nadir for areas shallower than 55 meters. 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 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). | Source Produced: Raw Multibeam Data

Process Step 2

CC ID: 599918
Description:

Raw Simrad data (.all format) were converted and processed using CARIS HIPS v5.4 and v6.0 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: HDCS Processed Multibeam Data

Process Step 3

CC ID: 599919
Description:

Acoustic backscatter mosaics are an important piece of information when characterizing surficial seafloor features and delineating benthic habitats. The multibeam backscatter data were corrected for geometric and radiometric distortions using Geocoder 3.2.1. 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 an ESRI Geotiff and XYB files (i.e., X,Y locations in NAD83 UTM Zone 20N and Backscatter values as measured in decibels dBs).
