Polymetallic Nodules (points)

The Geological Survey Ireland (GSI), as partner and Work Package 7 (Minerals) leader of EMODnet Geology Phase III, are compiling information on Polymetallic nodules. EMODnet partners are submitting the spatial extent of mapped polymetallic nodules and existing information; here you can view data collated thus far. The information presented here are of mapped extents of polymetallic nodules within participating surveys national Exclusive Economic Zones (EEZ). Polymetallic nodules are also known as manganese nodules. These ferromanganese concretions comprise mainly iron and ferromanganese oxides, with accessory minerals such as cobalt, copper and nickel, zinc, vanadium, platinum and molybdenum.
