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?

   Information unavailable from original metadata. (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
   Source_Contribution: Information unavailable from original metadata.
   

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

   Date: 07-Oct-2002 (process 1 of 5)

   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.dbf

   Date: 01-Dec-2015 (process 2 of 5)

   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 source information was incomplete and had to be modified to meet the standard. 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?
   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?
