Expedition with RV SONNE: Ecological impacts of deep-sea mining
Expedition MANGAN 2018 is the ninth cruise of the BGR to the German license area for the exploration of manganese nodules.
The investigations include:
- detailed studies of the benthic biodiversity,
- measurements of metal concentrations in (sub)bottom waters,
- the mooring of three ADCP current meters for analysis of the bottom current regime until April 2019, and
- 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 plan to continue our time series sampling for biodiversity analyses in two reference areas, for which annual samples have already been collected between 2013 and 2016.
