Why was the data set created?

These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey, Coastal and Marine Geology Program, Woods Hole Science Center. Geophysical data associated with this project were collected by NOAA NOS. Ground-truth data were collected during a survey (September 14-17, 2004) on the USGS R/V Rafael.

How was the data set created?

  1. From what previous works were the data drawn?
    SeaBOSS (source 1 of 1)
    USGS, unpublished material, Raw SeaBOSS photos and navigation.

    Type_of_Source_Media: digital files
    Source_Contribution: sea floor bottom photographs and navigation
  2. How were the data generated, processed, and modified?
    Date: unknown (process 1 of 5)
    Geographic location of each photograph was extracted from the survey vessel navigation string during post processing. MINI SeaBOSS sampler was lowered of Starboard side of survey vessel and lowered to seafloor. Vessel and sampler then drifted with wind and tide. Bottom Photograph location is recorded as survey vessel navigation which could differ by 2-5 meters depending on bottom currents, tide, and wind. 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. The original process steps had no process date, so unknown was used. Additionally, the source contribution information was virtually non-existent. An attempt was made to add minimal information based on knowledge of the SeaBOSS system. Most of the attributes had no attribute domain values, so this was set to Unrepresentable_Domain, with "Information unavailable from original metadata." Other minor edits were probably performed (title, publisher, publication place, etc.). 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.
