Benthic electromagnetic profiling at the Bay of Plenty, New Zealand

Magnetic susceptibility and electric conductivity within the uppermost meter of the seafloor were measured with high resolution along 33 coast-normal profiles in the Bay of Plenty (New Zealand), using the recently developed electromagnetic benthic profiler MARUM NERIDIS III. These parameters are used to determine magnetic mineral concentration and porosity of mostly volcanoclastic sediments between 2 and 35 m water depth to investigate distribution and formation of magnetic mineral enrichments on a storm-dominated shelf.
