What does this data set describe?

Title:
Sediment sample analysis for calcium carbonate of sample collected in the East and West Flower Garden regions, northwestern Gulf of Mexico outer shelf
Abstract:
This file contains location and carbonate content analysis of samples taken during Cruise No. FERL01052 aboard the NOAA Ship Ferrel. These samples were taken on East and West Flower Garden Banks of the Flower Gardens Bank National Marine Sanctuary between May 28, 2002 and June 3, 2002. The information collected during this cruise is intended for a preliminary geologic interpretation of the surficial sediment distribution in order to determine sites for future sample collection. The interpretations presented in this Open File Report are subject to change with future data acquisition.

Why was the data set created?

This ArcView shapefile contains the locations of sediment samples collected and analyzed by the U. S. Geological Survey, Woods Hole Field Center starting in May 2001 and ending in December 2001. Distribution of this dataset allows the user the ability to visualize the information in a Geographic Information system.

    Type_of_Source_Media: Microsoft Excel spreadsheet
    Source_Contribution:
    The Excel spreadsheet contains the available data on calcium carbonate composition for the bottom sediments produced by the USGS, Woods Hole Field Center. The basic structure of the file is a matrix where records are rows representing individual samples and the columns contain information on sample identification, navigation, classifications, analyzed parameters, and comments.
  2. How were the data generated, processed, and modified?

    The file caco3.xls was converted to a .dbf file and was imported into ArcView to create a table. This table was then converted to an ArcView shapefile to be used as a GIS layer in the project. Person who carried out this activity:

    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.). Modified the title to include more information. Attempted to modify http to https where appropriate. The metadata structure had format issues that were fixed. Added digital transfer information and a link to the data in the distribution section. Added the Larger Work citation. Attributes were incompletely defined and had to be modified to meet the standard. Added the Distribution_Liability. Removed extra metadata contact. 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:
