Title:
Locations of Sea-Floor Photographs Acquired During OSV BOLD Cruise 2010-015-FA Offshore in Eastern Long Island Sound (2010_015_997BOTPHOTOS, Geographic, WGS84)
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. Bathymetry and sidescan-sonar imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities in Long Island Sound, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. During October 2008 NOAA completed hydrographic survey H11997 offshore in eastern Long Island Sound, and during May 2010 bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Two interpretive data layers were derived from the multibeam echo-sounder and the ground-truth data used to verify them. For more information on the ground-truth survey see http://quashnet.er.usgs.gov/data/2010/10015/

Why was the data set created?

The purpose of this dataset is to release the locations and identifiers of 75 photographs and frame grabs of video from the sea floor collected at 28 stations on bathymetry data from offshore in eastern Long Island Sound in geographic, WGS84.

How was the data set created?

  1. From what previous works were the data drawn?
    The source information was incomplete and had to be modified to meet the standard. (source 1 of 1)
    The source information was incomplete and had to be modified to meet the standard. Assumed to be USGS., unknown, The source information was incomplete and had to be modified to meet the standard..

  2. How were the data generated, processed, and modified?
    Date: 2010 (process 1 of 6)
    GPS Navigation (degrees with decimal minutes to six places) and time updated every second were recorded and correlated with the times manually recorded in the SEABOSS log to register the still photographs. These locations were checked against the navigation on the videotape (degrees with decimal minutes to three places) and in cruise logs for verification; there was little offset. Frame grabs of the bottom video were used to produce images of the three stations where bottom photographs were not taken (i.e., 997-4, 997-7, and 997-21). Navigation for these frame-grab images came directly from the navigation recorded on the video. This information was manually input into an Excel 2003 (.xls) file and exported to create an ASCII file of this information. Shapefiles were created in ArcView 3.3 from the ASCII comma-delimited files by creating an Event Theme and then converting it to a shapefile. Person who carried out this activity:

    Edits to the metadata were made to fix any errors that MP v 2.9.30 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.). Fixed a bad link to an Excel file in the Identification_Information section. The source information was incomplete and had to be modified to meet the standard. 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. Compare the metadata dates to determine which metadata file is most recent.

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

  1. How well have the observations been checked?
    All attributes were checked in a consistent manner
  2. How accurate are the geographic locations?
    Navigation was by differential GPS. Although GPS gave the ship's position rather than that of the SEABOSS, the antenna was located less than 5 m from the block on the A-frame, water depths were generally shallow, and scope of the cable minimal. Therefore, SEABOSS offset from the antenna was less than 10 m.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Locations of all still photographs and frame grabs from video of the sea floor collected within the study area during the OSV Bold cruise 2010-015-FA were included in this data set. Total station numbers range from 997-1 to 997-28. Although 7 rolls of film were collected during the cruise, only a portion of the photographs were taken within this study area.
  5. How consistent are the relationships among the observations, including topology?
    No additional checks for topological consistency were performed on this data.
