Sampling data captured in Oceanic Exploration Research Based on geochemical and physical data we identified differences in the polymetallic nodule facies within the eastern German license area. Nodules in Prospective Areas # 1 are generally larger and show significantly higher contents of Ni and Cu as compared to the nodules in Prospective Area #2 which are smaller and are characterised by higher contents of Co. Furthermore, our study shows that sediment, which mainly consists of Si and Al oxides, contributes 13 % to the dry weight of the nodules on average. The method we used is quantitative and can thus be used for habitat mapping and be related to biodiversity and other environmental parameters
