The main objectives of this cruise were the characterization of hydrothermal systems at the Kermadec Arc and the understanding of their role for the global elemental budget of the ocean and for local chemical and biological processes in the water column and at the seafloor. Specific focus was on the role of chemical speciation and complexation and the influence of biological processes on the export and bioavailability of these elements, as well as on the geological, geochemical and biological diversity of these volcanic arc hydrothermal systems. Hydrothermal systems along volcanic island arcs are different to those at mid-ocean ridges because of their mostly shallow water depth and strong magmatic input into their fluids and hydrothermal plumes. As these plumes often reach up into the photic zone they discharge large quantities of material into the surface water layers.
