Ferromanganese Crust Data Set
NOTE: PLEASE CITE ORIGINAL REFERENCE WHEN USING THESE DATA
The USGS Ferromanganese Crust data set was compiled by F.T. Manheim and C.M. Lane-Bostwick of the US 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 Ocean: A Review and Comprehensive Database. Data include excerpts from the SIO nodule file, the NGDC marine minerals data base, Japanese sources, a PhD 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 and MMS Marine Minerals CD-ROM data set released by NOAA in October of 1992.
Note: All of the NGDC and SIO data in these files are also represented in the NOAA and MMS Marine Minerals Database elsewhere on this CD-ROM. Most of the USGS crust data are also contained in the Marine Minerals Database. NGDC-coded data in the USGS crust data files were transmitted to the USGS prior to final checking and may not match data retrieved using the CD-ROM software. USGS crust data are as received from the USGS and have not been edited or inspected. For questions about the data in these files, or to obtain a copy of the associated Open-File Report, please contact the US Geological Survey in Woods Hole, MA.
