Comment:
From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

| ARIES-012D | ARIES-012D-1S | 0 | Surface | Mn crust | 1 | 2.5 thick | Rock; altered basalt | A trapezium shaped almost flat sample with a surface area of about 56 cm2 thickness of about 4.5 cm with a 2.5 cm manganese crust. The rest is an altered basalt which has a few patches of Mn here and there. | Fig1-12D_Sharma_1979.jpg | hdl:10013/epic.48913.d002 |
| ARIES-015D | ARIES-015D-1S | 0 | Surface | Mn crust | 1 | 2.2 thick | Rock; consolidated sedimet | This sample looks like a right-angle-triangle with almost no basaltic cover at the bottom. Only a few spots of clay can be seen. It has an area of about 125 cm2 with a 2.2 cm thick Mn crust. | Fig1-15D_Sharma_1979.jpg | hdl:10013/epic.48913.d003 |
