Research Theme B "Ocean & Seafloor"

From the coast to the deep sea the seafloor covers more than 70% of the Earth’s surface. Thereby it hosts a huge diversity of ecosystems, provides a wealth of resources, archives information about Earth’s history, connects the interior of the Earth to the hydrosphere, and interferes with human usage especially in the coastal zones. In the research theme “Ocean & Seafloor”, we address a variety of aspects within a multidisciplinary consortium:

  • Sedimentology – investigating the deposition of sediments as well as the structure of sedimentary features,
  • Morphodynamics – analyzing the interplay of hydrodynamics, sediments and morphology in shaping the “seascape”,
  • Seismology – imaging the sub-seafloor to assess the long-term development of the seafloor,
  • Fluids & Gases – assessing the presence of fluids and gases in the lithosphere and their exchange with the hydrosphere,
  • Petrology – understanding the fate of newly formed ocean crust from generation to alteration.
