Why was the data set created?

The purpose of this data layer is to make available a subset of a data set produced by Larry Ward and others at the University of New Hampshire. This data layer contains information for those samples with raw grain size data which are located on the inner continental shelf from off New Hampshire, Gulf of Maine.

How was the data set created?

  1. From what previous works were the data drawn?
    Information unavailable from original metadata. (source 1 of 1)

  2. How were the data generated, processed, and modified?
    Date: 15-Jan-2003 (process 1 of 5)
    Textural and lithologic data from off New Hampshire were reorganized in Excel and exported to an ASCII file. Stations and sediment data were imported from the ASCII text file to an ArcView table. The table was later converted to an event theme 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.). 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.
