Abstract:
Concentrations of the rare earths have been determined in ten modern manganese nodules from the Atlantic, Pacific, and Indian Oceans, the Baltic Sea, and Lake Charlotte in Nova Scotia. A nodule from a Paleozoic era sea in Montana, a manganese film from a coral found on the Mid-Atlantic Ridge, and samples of the manganese and phosphorite pavements fround on the Blake Plateau were also analyzed. The manganese pavement, a mixed manganese-phosphate concretion from the Blake Plateau and one of the Atlantic nodules with its underlying red clay core were segmented and analyzed.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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