Abstract

This dataset contains a unified GeoTiff with 30x30 meter cell size representing the backscatter intensity of the Charleston Bump off of the South Atlantic Bight, derived from data collected in 1997. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with the Lamont Doherty Earth Observatory as well as the R/V Ewing , and private sector partners, acquired multibeam bathymetry data off the Charleston Bump to identify habitats for deep water coral ecosystems from 05/03/1997 to 05/05/1997. Data was acquired with a hull-mounted Atlas Hydrosweep multibeam echosounder (95 kHz). It was processed by the College of Charleston Department of Geology 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 17 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. The CARIS Export option "BASE Surface to Image" was then used to create a GeoTiff of the priority areas. The slope raster surface was exported as a 50m GeoTiff and the slope was derived by using the ESRI ArcMap10 Spatial Analyst Slope tool.habitats.

Abstract:

Purpose:

This multibeam data was processed as part of a mulitagency cooperative deep-sea coral assessment. The multibeam component of the cruise was intended to both provide fine scale acoustic imagery of known deep coral sites, as well as serve as a nautical survey for charting purposes. The backscatter component will be used to characterize the seafloor topography to identify and predict deep water coral habitats.

Data Quality

Completeness Report:

This GeoTiff is sourced from a CARIS 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 Grid. Some positional shifts may have occurred between the original data points and the transformed grid.

Conceptual Consistency:

As the survey was not conducted to meet IHO standards, 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: 599300
Description:

For this project, data was collected aboard the R/V Maurice Ewing from 05/03/1997 to 05/03/1997. Multibeam data were acquired in .mb21 format with a hull-mounted Atlas Hydrosweep multibeam echosounder. Line spacing for acquisition was three times the water depth, and data was retained out to 60 degrees from nadir. Heave, roll, pitch and heading correctors were collected using an Applanix POS/MV Model 320 V4 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 NOAA's Velocwin V8.85 software, then applied directly to the raw data. Positioning was obtained using Trimble Zephyr GPS receivers. Data was reduced to Mean Lower-Low Water (MLLW) using final approved tides from NOAA COOPS, based on National Water Level Observation Network (NWLON).

Process Date/Time: 1997-01-01 00:00:00
Source: Raw Multibeam Data

Process Step 2

CC ID: 599301
Description:

Raw .mb21 data were converted and processed using CARIS HIPS 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.

Process Date/Time: 1997-01-01 00:00:00
Source: HDCS Processed Multibeam Data

Process Step 3

CC ID: 599302
Description:

After being submitted to CCMA by the contractor, CARIS HIPS v6.0 was used to generate a CARIS BASE surface (similar to a DTM), based on weighted swath angle, from the processed HDCS data. Then CARIS export tool "BASE Surface to Image" was used to export a GeoTiff in NAD83 UTM zone 17N. The slope was derived using the ESRI Arc10 Spatial Analyst slope tool.
