Former Research Group Marine Geophysics 2002 - 2024

We investigate the spatial distribution and temporal variability of marine sediments from the coast down to the deep sea to reconstruct their origin, transport, diagenesis and chrono­logy. Using paleo- and rock magnetic as well as optical methods we study the composition and magnetization of natural sedimentary iron minerals, drawing conclusions on past chan­ges in climate conditions, ocean circulation, plate tectonics and Earth´s magnetic field.

Working Area

Our current working areas are the N and SW Pacific as well as continental margins of SE Africa, Eastern Canada and W Antarctica. In the framework of student and contract pro­jects, we also survey geological and archeo­logical structures in Germany.

Methods

Our two automated cryogenic magnetometers and three core logging systems enable rapid and sensitive geophysical analyses of sediment cores. We also run instruments for magnetic high- and low-temperature experiments. Four mobile Overhauser magnetometers are used for field and marine magnetic surveys. Our EM profiler NERIDIS III can map magnetic and electric properties of the shallow seafloor at high resolution.
