What does this data set describe?

Title: Fisheries Sediment Data (WIGLEY65 shapefile)
Abstract:
This is a part of the National Geophysical Data Center (NGDC) Seafloor Surficial Sediment (Deck 41) Data File. Deck 41 is an original data file created by the Marine Geology and Geophysics Group of NGDC from 1970-1975, abstracted from unpublished material contributed to NGDC by multiple groups of individuals. No updates of Deck 41 have been added since 1975. The data that comprise this portion of Deck 41 were generated by R.L. Wigley during 1965 aboard ALBATROSS IV cruises 65-2, 65-13, and 65-14.

Why was the data set created?

The purpose of this data layer is to provide a part of the Deck 41 data file in a form that could be used to interpret surficial sediment distributions off the northeastern United States.

How was the data set created?

  1. From what previous works were the data drawn?
    Information unavailable from original metadata. (source 1 of 1)
    Wigley, R.L., Unpublished Material, Raw Data Sheets: Bureau of Commercial Fisheries, Woods Hole, MA.

    Other_Citation_Details:
    Data collected during 1965 aboard the ALBATROSS IV during cruises 65-2, 65-13, and 65-14
    Type_of_Source_Media: Scanned raw data sheets
    Source_Contribution: Information unavailable from original metadata.
  2. How were the data generated, processed, and modified?
    Date: 13-Sep-2002 (process 1 of 5)
    Scanned images of the original raw data sheets were downloaded from the NGDC Seafloor Surficial Sediment (Deck 41) Data File. Lithologic descriptions, grain-size data, and sample identifiers were manually entered into Microsoft Excel and saved as an ASCII text file. The ASCII file was imported to an ArcView table. The table was later converted to an event theme in ArcView and saved as the final shapefile. Person who carried out this activity:

    Edits to the metadata were made to fix any errors that MP v 2.9.32 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.). Minor fixes to the attribute format for some attributes was needed. 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 by the compilers in a consistent manner.
  2. How accurate are the geographic locations?
    No information on navigational methods was provided with this data set , but navigation was probably by Loran A. Navigational accuracy is unknown.
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    This data set contains fields that are only a subset of those fields in the NGDC Seafloor Surficial Sediment (Deck 41) Data File. This data set contains grain-size data, textural descriptions, navigation, and sample identifiers for 383 stations.
  5. How consistent are the relationships among the observations, including topology?
    No additional checks for topological consistency were performed on this data.
