Content Description
Abstract: The USGS Ferromanganese Crust data set was compiled by F.T. Manheim and C.M. Lane-Bostwick of the U.S. Geological Survey, Woods Hole, MA. The data set consists of tables corresponding the USGS Open-File Report 89-020 "Chemical Composition of Ferromanganese Crusts in the World Oceans: A Review and Comprehensive Database." Data include excerpts from the SIO nodule file, the NGDC marine minerals data base, Japanese sources, a Ph.D. thesis, analyses performed at the Bureau of Mines, and analyses performed at other laboratories under the direction of the USGS. These data are also included on the NOAA & MMS Marine Minerals CD-ROM data set released by NGDC in October of 1992. The USGS crust are also available for download from NGDC's Web server.
Purpose: Marine Minerals and Exploration
