Manganese nodules collected from the North Penrhyn Basin are characterized by low content of Mn and Fe
medium content of Ni and Cu
and medium Mn/Fe ratios. The average content of Ni plus Co is 1.11%
maximum 1.89%. Ni content slightly exceeds the Cu content in the nodules. Ni and Cu are strongly correlated with Mn
whereas Co is strongly correlated with Fe. Nodules containing Ni+Cu+Co near or in excess of 1% are rich in Mn and have a high Mn/Fe ratio. Those with highest content of Ni+Cu+Co are concentrated at or near the carbonate compensation depth. Nodules metal contents vary with latitude and have a reciprocal relationship with abundance. Contents of Mn
Ni
Cu and Ni+Cu+Co are high in nodules found at 2–6°S and vary decreasingly toward 1°N and 12°S
whereas Co content varies increasingly from 2°S towards 12°S. Nodule compositional variations with latitude are controlled by biological productivity
carbonate compensation depth
sedimentation rate
and bottom current.
