RV POSEIDON Fahrtbericht / Cruise Report POS524 - GrimseyEM: Geophysical and geological investigations in the vicinity of the Grimsey Hydrothermal Field offshore Northern Iceland for the assessment of the geothermal potential and the exploration for potential mineralizations within the seafloor, Reykjavik (Iceland) - Bergen (Norway), 7.6 - 26.6.2018

In the marine environment elevated electrical conductivities may be caused by sulfide mineralizations within the seafloor as well as hot saline pore fluids. Such conductive targets may be studied with suitable electromagnetic systems like the novel coil-system MARTEMIS1, which we previously used to investigate a known zone of sediment covered mineralization at the Palinuro Seamount (cruises POS483 \&amp; POS509) and in the vicinity of the TAG hydrothermal mound at the Mid Atlantic Ridge (cruise
