Abstract:
Manganese nodules, micronodules, and crusts were encountered in surface sediments, and at depth, in 6 of the 10 sites drilled during DSDP Leg 29 south of New Zealand and Tasmania. Major concentrations of surface nodule pavements occur on and adjacent to the Campbell Plateau south of New Zealand, south of the Tasman Rise, and in the South Tasman Sea. These deposits are found on top of erosional unconformities, which span tens of millions of years and reflect scouring by strong bottom currents. Micronodules were also found at depth throughout most of these cores. Their occurrence apparently is dependent upon a number of environmental factors.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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