| Summary: | This report offers a description and further geochemical analysis of ocean manganese manganese deposits material available at the time in the New Zealand Oceanographic Institute collection. In particular, during cruise 36 of the USNS ELTANIN, large quantities of manganese nodules were collected at two stations in the South Tasman Basin, west of the Macquarie Ridge and north of the Indian-Antarctic Ridge, and sub-samples donated to the NZOI. The study covers also two large manganese nodules recovered by the R/V Vityaz South of Rarotonga (Cook islands), manganese crusts from phosphatized outcrops of the Aotea Seamount and further pea-shaped concretions from the Philippine Sea. ... : 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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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. ... |
