Frequently-anticipated questions:

What does this data set describe?
    Title: HATHAWAY71: Textural Data from the Continental Margin Program
    Abstract:
    This data set contains sediment grain size and textural information from the Continental Margin Program. The program was a joint collaboration between the U.S. Geological Survey and the Woods Hole Oceanographic Institution during the 1960s to conduct a geological reconnaissance investigation of the continental shelf and slope off the Atlantic coast of the United States. Only those records with complete size analyses are included in this data set. Other stations where only lithologic descriptions are available have been excluded.

    Entity_and_Attribute_Overview:
    Navigation, grain size data, textural and lithologic descriptions, statistics, and identifiers for the Continental Margin Program stations from the Gulf of Maine, Georges Bank, and continental shelf and slope off southeastern New England.

Who produced the data set?

  1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)

  2. Who also contributed to the data set?

    Please review the cross reference information for the original data set credit to Hathaway (1971), and Larry Poppe for creating the ArcView shapefile.

  3. To whom should users address questions about the data?

Why was the data set created?
The purpose of this data layer is to make available a subset of the Hathaway data set. This subset contains information for those samples with raw grain size data, and which are located in/on the Gulf of Maine, Georges Bank, and southeastern New England continental shelf.

How was the data set created?
  1. From what previous works were the data drawn?

    (source 1 of 1)
    Hathaway, J.C., 1971, Data File: Continental Margin Program Atlantic Coast of the United States: Woods Hole Oceanographic Institution Reference No. 71-15, v. 2, 496 p., Woods Hole Oceanographic Institution, Woods Hole, MA.

    Type_of_Source_Media: paper

  2. How were the data generated, processed, and modified?

    Date: 07-Oct-2002 (process 1 of 1)
    Continental Margin Program data from Gulf of Maine, Georges Bank, and the continental shelf and slope off southeastern New England were clipped from the whole dataset of the Continental Margin Program 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.

    Data sources produced in this process:

    • hathaway71.shp
    • hathaway71.shx
    • hathaway71.dbf

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?

    Navigation was variously performed by Loran A, line of sight, and RADAR. Navigational accuracy is unknown.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Sample locations, grain size data, textural descriptions, statistics, and identifiers for 1252 grab sample stations.

  5. How consistent are the relationships among the observations, including topology?

    No additional checks for topological consistency were performed on this data.

How can someone get a copy of the data set?
Are there legal restrictions on access or use of the data?

Access_Constraints: None
Use_Constraints: None

  2. What's the catalog number I need to order this data set?

    Regional Mapping of Surficial Sediments: Gulf of Maine and Georges Bank, Aggregates and Habitats Projects, hathaway71.shp

  3. What legal disclaimers am I supposed to read?

    Although this data set has been used by the U.S. Geological Survey, no warranty, expressed or implied, is made by the USGS as to the accuracy of the data and/or related materials. The act of distribution shall not constitute any such warranty, and no responsibility is assumed by the USGS in the use of these data or related materials.

  4. How can I download or order the data?

  5. What hardware or software do I need in order to use the data set?

    The data is available in ArcView shapefile format. The user must have ArcView 3.0 or greater software to read and process the data file. In lieu of ArcView, the user may utilize another GIS application package capable of importing data.
