Description:

Abstract:

1-m resolution acoustic-backscatter data were collected during a February 2013 SWATHPlus survey offshore of the Hawaiian Islands of Maui and Kaho`olawe. Data were collected and processed by the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC), with fieldwork activity number A-01-13-HW. The 1-m backscatter data are provided as a GeoTIFF file.

Purpose:

In February 2013, staff from the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) collected bathymetry and acoustic backscatter data offshore the islands of Maui (Olowalu, Pu`unoa Point) and Kaho`olawe (Kuia Shoal), Hawaii using an interferometric bathymetric sidescan sonar system mounted to the hull of the vessel AlyceC. The acquisition was conducted to support seafloor characterization and benthic habitat mapping efforts in selected nearshore coral reef environments of Hawaii. These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to identify bathymetric features. These data are not intended to be used for navigation.

Supplemental_Information:

Additional information about the field activities from which these data were derived is available online at: https://cmgds.marine.usgs.gov/fan_info.php?fan=A0113HW Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Estimated to be no less than 1 m, owing to water depth and total propagated uncertainties of the mapping systems, which include sonar system, position and motion compensation system, and navigation, as well as data processing that includes sounding cleaning, gridding, and datum transformations.

Lineage:

Process_Step:

Process_Description:

In February 2013 the USGS, PCMSC mapped two sites offshore the islands of Maui (Olowalu and Pu`unoa Point) and Kaho`olawe (Kuia Shoal) in Hawaii. A SEA 234-kHz Interferometric SWATHplus-M bathymetric sonar system was pole-mounted to the starboard gunwale of the vessel Alyce C. Water column sound velocity data that was collected throughout the survey was applied to the data during collection as well as tide data from a local tide station. Post-processed Smoothed Best Estimate of Trajectory (SBET) files were merged with the survey line files using BathySwath software and then the line files were imported into Caris software. Backscatter imagery was generated using Caris processing techniques. The backscatter image was exported as a GeoTIFF file in UTM-4, WGS-84 coordinates.
