Title:
Location of Sea-Floor Photographs Acquired During U.S. Geological Survey (USGS) Cruise 2013-005-FA in Block Island Sound (Geographic, WGS 84, 2013-005_298BOTPHOTOS)
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.

    Entity_and_Attribute_Overview:
    Data layer attributes include date and position photograph was acquired; station and photograph identifiers. The naming convention for photographs is a 3-number location identification (298, referring to NOAA Survey H12298 in Block Island Sound), underscore, the station number, and a letter of the photograph at that station (multiple photos are often taken at a single location), and the resolution of the photograph if it is not full resolution (mr for medium resolution, and tn for thumbnail). For instance, 298_34amr.jpg is a photograph from Survey H12298, station 34, photo a, medium resolution and is in JPEG format.
    Medium resolution photographs can be hyperlinked in this shapefile. In order to effectively utilize this attribute in ArcGIS, the user must follow a couple of steps. First, the user must open the Layer Properties of the bottom photograph shapefile within ArcMap - select the Display tab - and click on the check box next to "Support Hyperlinks using field:" and the field selected from the dropdown menu needs to be "PHOTO_MR". The hyperlink is set to a document. Additionally, a hyperlink base must be supplied in the ArcMap document (mxd) to complete the full path to the images. This is accomplished from File - Document Properties. On the Summary tab there is a section for "Hyperlink base". The text supplied here needs to be the disk information preceding "data" in the full path to the image. If the data are being read from a DVD, this would be the drive letter such as F:\.
    The excel, shapefile, and comma-delimited text files have the same fields of information with the same headers as the shapefile attribute table.

Why was the data set created?

The purpose of this dataset is to release the locations and identifiers of 159 bottom photographs collected at 36 stations based on topographic data of the sea floor in Block Island Sound. The photos were collected with a modified Van Veen grab sampler modified to carry still and video camera systems (small SEABOSS) during USGS survey 2013-005, in June 2013.

    Time recorded in Exif headers of the photographs was matched with navigation data using a script that created a shapefile of the photograph locations. The data from the DBF of the shapefile was opened in an Excel (.xls) file (2010 version, but saved as an Excel 97-2003 Worksheet) and other fields were added and populated.

    ArcMap 9.3 was used to create a shapefile from the Excel file using Tools-Add XY Data to import the excel file with Longitude in the x field and Latitude in the y field.

    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 only had time period of content, which was the same as the dataset time period of content, so the element was removed. 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. Compare the metadata dates to determine which metadata file is most recent. Person who carried out this activity:

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, water depths were generally shallow and scope of the cable minimal. Therefore, SEABOSS offset from the antenna was less than 10 m. The time on the camera was synchronized with GPS and verified by comparing the time in the Exif header with a photograph of the written GPS time. Although there was an offset of one second, this error is assumed to be due to the operator taking a photograph slightly before the written GPS time and was not corrected.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    Locations of all still photographs of the sea floor in the Block Island Sound H12298 study area collected during the R/V RAFAEL cruise 2013-005 were included in this dataset. Other photographs were collected during cruise 2013-005 that lie outside the study area.
  5. How consistent are the relationships among the observations, including topology?
    No additional checks for topological consistency were performed on this data.
