Ziel der Reise / Objectives of Cruise:
The RV SONNE cruise SO-262 in April/May 2018 had three major aims. First, the exploration of a new prospective manganese nodule field in the eastern part of the German license area for the exploration of polymetallic nodules within the Clarion-Clipperton Zone of the Pacific Ocean. Second, the recovery of at least 10 tons of manganese nodules for metallurgical experiments at pilot plant scale. And third, in preparation for a disturbance experiment scheduled for April/May 2019 in the German license area, high-resolution baseline environmental data were required specifically from the test area. The investigations include (i) detailed studies of the benthic biodiversity, (ii) measurements of metal concentrations in (sub)bottom waters, (iii) the mooring of three ADCP current meters for analysis of the bottom current regime until April 2019, and (iv) the mooring of a sediment trap for one year in order to determine background particle fluxes in this mesotrophic part of the Pacific Ocean. Furthermore, we planned to continue the sampling of time series for biodiversity analysis in two reference areas for which annual samples for the period between 2013 and 2016 were already available. All three major aims were achieved. The cruise started in Guayaquil on April 6 and we steamed to the license area at 11?50' N / 117?W where we arrived on April 13. After 30 working days and a total of 177 deployments we completed our working program and left the license area to steam towards Suva where we arrived on May 28.
