Abstract:
Manganese nodules collected from four sites in the N.W. Indian Ocean by R.R.S. Discovery have been analysed for a range of elements. At two of the sites, samples were collected from two morphological populations, at one of these sites each population being a distinct chemical population also. In addition, considerable differences have been observed in the composition of morphologically similar modules from sites a few miles apart. The information obtained is of significance in any consideration of the genesis of the nodules and could have practical implications in the event that manganese nodules become a potential source of manganese and other metallic elements.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
