Title:
Grayscale GeoTIFF Image of the 1-m Sidescan-Sonar Data From National Oceanic and Atmospheric Administration (NOAA) Survey H12298 in Block Island Sound (UTM Zone 19, NAD 83, H12298_1MSSS_UTM19.TIF)
Abstract:
The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetric and sidescan-sonar data, originally collected by NOAA for charting purposes, provide a framework for research and management activities along western Block Island Sound, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During June 2013, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretations were derived from the multibeam-echosounder, sidescan-sonar, sedimentary, and photographic data collected in Block Island Sound. For more information on the ground-truth survey see https://cmgds.marine.usgs.gov/fan_info.php?fan=2013-005-FA.

  7. How does the data set describe geographic features?
    Entity_and_Attribute_Overview:
    A continuous-coverage sidescan-sonar image of NOAA survey H12298 in UTM Zone 19, NAD 83. Data values in this grayscale image range from 0-254; 255 is the 'no data' value. High numbers indicate high reflectance which corresponds to a harder bottom, while low numbers indicate low reflectance and a softer bottom (finer grained sediment) and acoustic shadows.

Why was the data set created?

To release a GeoTIFF of the sidescan-sonar data generated during NOAA survey H12298 in Block Island Sound, in UTM Zone 19, NAD 83.

How was the data set created?

  1. From what previous works were the data drawn?
    Information unavailable from original metadata. (source 1 of 1)
    NOAA, Unpublished Material, H12298 CARIS Dataset.

    Type_of_Source_Media: disc
    Source_Contribution:
    The original sidescan-sonar data acquired with a Klein 5000 sidescan-sonar system during NOAA survey H12298 aboard launches deployed from the NOAA ship Thomas Jefferson.
  2. How were the data generated, processed, and modified?
    Date: 2011 (process 1 of 8)
    The sidescan-sonar data were acquired with a Klein 5000 high-speed sidescan-sonar system hull mounted to or towed behind one of two 8.5-m aluminum launches deployed from the NOAA ship Thomas Jefferson. The systems consist of a Klein 5500 towfish, either towed or hull-mounted, a Transceiver/Processing Unit (TPU), and a computer for user interface; has an operating frequency of 455 kHz; and was set to sweep 100 m to either side of the launch tracks. The Klein 5000 system is distinct from other commercially-available side scan sonars in that it forms 5 simultaneous, dynamically-focused receiver beams per transducer face. This improves along-track resolution to approximately 20cm at the 100m range scale, even when acquiring data at up to 10 knots. Across-track resolution is typically 7.5cm at the 100m range scale. The achievable 20cm resolution meets the NOAA Hydrographic Surveys Specifications and Deliverables Manual (HSSDM) for object detection. Klein SONARPRO was used to acquire the Klein 5000 sidescan sonar data; CARIS SIPS (Sidescan Image Processing) software was used to process the sidescan data and to produce a composite sidescan-sonar image at 1-m horizontal resolution and projected into UTM Zone 19 NAD 83.

    The image was imported into Adobe Photoshop CS2 in order to apply a linear stretch (i.e., increase the dynamic range of the data), to change image from RGB to 8-bit grayscale, to invert the grayscale to make strong reflections light tones and weak reflections returns darker tones, and to assign a 'NO DATA' value (255).

    Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Attempted to modify http to https where appropriate. The source information was incomplete and had to be modified to meet the standard. Updated the link to the field activity. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
  2. How accurate are the geographic locations?
    Navigation was by differential GPS using Trimble DSM212L DGPS receivers (accurate to <1m). Layback corrections were applied to the data during processing.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    All collected data were processed and used to produce this dataset. Sidescan-sonar data were only collected in shallow waters of the survey area and together with the bathymetry data provide complete coverage of the survey area.
  5. How consistent are the relationships among the observations, including topology?
    No additional checks for consistency were performed on this data.
