Analysis of Mn-nodules from the Pacific

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.
