Abstract:
This paper, explores the possibility of using manganese nodules for studying the rates of authigenic removal of trace elements to the ocean floor, i.e. considering only trace elements in hydrogenous phases (Goldberg, 1964) in sediments. It follows the then recent detailed investigations of physiochcmical properties of manganese nodules made by others. In view of the various arguments the developed regarding a slow and possibly entirely authigcnic growth of manganese nodules, the authors were led to the measurements of a host of trace elements in several already radiomctrically dated manganese nodules and sediments.

Comment:
Only the 1cm Mn rich nodule outer rind or Mn crust upper part have been analysed.
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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.
