XYZ ASCII format high-resolution bathymetry data generated from the 2003, 2007, and 2009 combined multibeam sonar survey of Pulley Ridge, Gulf of Mexico, Key West, Florida.

This disk or set of disks contain high-resolution multibeam and backscatter maps of an area North of Madison-Swanson (29.1667N, 85.6667W), in the West-Florida shelf, not included in a previous mapping expedition to the area. It includes the following products: 1) ESRI .ASC files, 2) Text file containing X, Y, Z postprocessed bathymetry data, 3) Geotiff and JPEG images from of bathymetry, 4) GeoTiff and JPEG images of backscatter, 5) Fledermaus files of the survey locations. All products are available contacting the distributor. Some data sets are also posted on NOAA's Coral Reef Information System (CoRIS) at www.coris.noaa.gov. Another product that will not be distributed, but will be used as input to habitat classification software (QTC MultiView), are raw data files logged to disk using the Simrad EM3000 multibeam system data acquisition software. These raw files contain packets of information (depth soundings, navigation, attitude, sound velocity profiles, UTC time) that the acquisition software logged sequentially in time. The raw data format is available from Kongsberg-Simrad. The multibeam system was provided by University of South Florida, College of Marine Science and the support vessel was the Florida Institute of Oceanography R/V Suncoaster.

The NOAA Fisheries laboratory in Panama City, Florida coordinated an acoustic survey at the new proposed Marine Protected Areas in the South Atlantic Bight area June 20- July 7th, 2005. This metadata record is the parent record for the multi-beam echosounder (MBES) survey at the South Carolina A proposed MPA, which includes the following products: 1) XYZ ascii table created from the grid, 2) colored coded shaded geotiffs from the grid, 3) backscatter mosaic, 4) XYA (amplitude) ascii table created from the mosaic, and 5) geotif of backscatter draped on the bathymetric grid. All products are available contacting the distributor. Some data sets are also posted on NOAA's Coral Reef Information System (CoRIS) at www.coris.noaa.gov. Another product that will not be distributed, but will be used as input to habitat classification software (QTC MultiView (website)), are raw data files logged to disk using the Simrad EM3002 MBES data acquisition software. These raw files contain packets of information (depth soundings, navigation, attitude, sound velocity profiles, UTC time) that the acquisition software logged sequentially in time. The raw data format is available from Kongsberg-Simrad (website). The MBES system was provided by Seafloor Systems Inc. and the support vessel was UNCW's 70-ft. R/V Cape Fear. This survey is part of an on-going partnership effort funded by the NOAA Coral Reef Conservation Program (CRCP). This survey was funded by a CRCP grant to Andrew David, NOAA Fisheries - Panama City, and Andrew Shepard, NURC/UNCW (The National Oceanographic and Atmospheric Administration's Undersea Research Center at the University of North Carolina at Wilmington). In addition to partners above, other partners include UNCW's Spatial Analysis Lab, US Geological Survey, and the S. Atlantic fishery Management Council.

XYZ ASCII format high-resolution bathymetry data generated from the 2010 multibeam sonar survey of the West Florida Shelf-The Edges, Gulf of Mexico, Appalachicola, Florida.

XYZ ASCII format data generated from the 2001 multibeam sonar survey of the West Florida Shelf, Gulf of Mexico. The data include high-resolution bathymetry and calibrated acoustic backscatter.

An Ellipsoidally Referenced Survey (ERS) using two Teledyne Reson SeaBat T50-P multibeam echosounders, in dual-head configuration, was conducted by the U.S Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) at Crocker Reef, the Florida Keys October 10-28, and December 5-8, 2017. This dataset, Crocker_2017_MBB_xyz.zip, includes the processed elevation point data (x,y,z), as derived from a 1-meter (m) bathymetric grid.

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) collected multibeam echosounder (MBES) bathymetry and sonar backscatter data offshore of Wallops and Assawoman Islands, Virginia in June 2024. This USGS data release includes the corresponding processed MBES-derived elevation points (xyz) and a backscatter mosaic (tag image file format [TIFF]) as part of Field Activity Number (FAN) 2024-310-FA. MBES and backscatter data were acquired using two Teledyne Reason SeaBat T50-P MBES in a dual-head configuration. Additionally, nearshore single-beam echosounder (SBES) and land topographic elevations, as well as Chirp seismic data, were concurrently collected as a part of FAN 2024-310-FA; those data are available as separate data releases (Lyons and others, 2025; Forde and others, 2025).

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) collected single beam echosounder (SBES) and differential global positioning system (DGPS) elevation data in the nearshore and beach environments of Wallops and Assawoman Islands, Virginia, in June 2024. This USGS data release includes the processed SBES and DGPS elevation point data (xyz) for Field Activity Number (FAN) 2024-310-FA. The SBES data were acquired using survey equipment mounted on personal watercrafts (PWCs) R/V Chum and R/V Shark, and the DGPS data were acquired using GPS antennas mounted on a utility terrain vehicle (UTV) or GPS backpack. Multibeam echosounder (MBES) and chirp seismic data were collected concurrently as part of FAN 2024-310-FA; those data are available as separate data releases (Forde and others, 2025; Bemelmans and others, 2025).
