Entity_and_Attribute_Overview:
The attribute definitions are based on information from the README.TXT file that was downloaded from NGDC at the same time as the data file.
Entity_and_Attribute_Detail_Citation:
Where available, the definitions of the attributes were first derived from the README.TXT file that was downloaded with the ASCII files from NGDC. In the event a definition was not available from that source, then the following reference was use:
Manheim, F.T., Lane-Bostwick, C.M., 1989, Chemical composition of ferromanganese crusts in the world ocean: A review and comprehensive database: U.S. Geological Survey Open-File Report 89-020.
Unfortunately, some of the attributes or their enumerated domains were not adequately described in either place.
