Ferromanganese nodules and crusts chemical analysis of BGR samples from the Midpac '81 expedition with R/V Sonne (SO18)

The Midpac '81 (SO18) exploration voyage with the R/V Sonne was a first step to study the regional distribution, nature and formation of Co-rich manganese crusts over submarine mountains. The expedition involved scientists from Preußag AG, the BGR Hanover, the University of Hamburg, the GKSS, the IfM Bremerhaven, the University of Bremen, the Technical University Clausthal and a USGS Woods Hole team led by F. T. Manheim. Part of the recovered samples were analysed for their main and trace chemical composition in the BGR Hanover using Atomic absorption spectrophotometry (AAS).
