SUMMARY

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 & MMS Marine Minerals CD-ROM data set released by NGDC in October of 1992.

NGDC Note: All of the NGDC and SIO data in these files are also represented in the NGDC Marine Minerals Database elsewhere on this CD-ROM. Most of the USGS crust data are also contained in the Marine Minerals Database. NGDC 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 by NGDC. 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.

SEARCHABLE DATA INVENTORY

NGDC/WDC GMG, Boulder archives a wide variety of digital marine geology data collections, paper reports, microfilm, etc. containing sediment and hardrock data. Many of the digital files are available for direct download. Sample-by-sample inventory information for all data, regardless of format available from NGDC are fully searchable through the marine geology inventory (GEOLIN).
