Submarine canyons occur at the edge of the continental shelf and cut across the slope and rise along the U.S. east coast. Three of these canyons (Oceanographer, Lydonia, and Gilbert) are situated south of Georges Bank. Gravity cores and grab samples were collected as part of a study of the active processes and sediment distributions within these features. The results of the textural analyses are contained in this data layer.
The purpose of this data layer is to provide a digital version of the sediment data published in Schwartz (1965).

All attributes were checked by the compilers in a consistent manner.
No additional checks for topological consistency were performed on these data.
Grain-size data, textural descriptions, navigation, and identifiers are provided for 50 stations.
Navigation was by Loran A. Inasmuch as the shore locations were not reported and the accuracy of Loran A is dependent on the distance from the stations, accuracy of the navigation is unknown.

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.
