Ziel der Reise / Objectives of Cruise:
1. Recover osmo-pumps and in-situ growth chambers from the 71 degrees N hydrothermal fields at the southern part of the Mohns ridge (close to Jan Mayen) by using ROV.\n2. Locate hydrothermal field, perform bathymetric mapping, and collect rock samples by dredging and sediment by gravity coring at the Mohns-Knipovich bend.
