Changes in version 1.1:


A linked data representation of 299 undersea features and their spatial extents has been added to the dataset (selected from the 311 features included in the 
shapefile).

The FGDC-CSDGM metadata has been updated to reflect the addition of linked data; most notable are revisions to the Data_Quality_Information, 
Entity_and_Attribute_Information, and Distribution_Information. The updated metadata also includes other minor additions and corrections.

The text of the open-file report has been updated to reflect the addition of linked data; most notable are revisions to the Dataset and Data Sources sections 
of the report. All hyperlinks in the text have been checked and corrected as necessary to eliminate link rot. The updated text also includes other minor 
additions and corrections.
