Chemical analysis of manganese deposits from the Southern Ocean recovered during campaign ELT36 (R/V Eltanin)

Manganese nodules and ferromanganese crusts deposited on igneous rocks from the Southern Ocean have been chemically analysed after dessication. Al, Ba, Ca, Co, Cu, Fe, Mg, Mn, Mo, Ni, P, S, Si, Ti, V and Zr were analysed by direct reading on a vacuum optical emission spectrometer. K, Na, Pb, Sr and Zn were determined using an atomic absorption spectrophotometry.
