Scientific Objectives

  • Reconstruction of the climate dependent temporal development of the Azores front at intermediate waters of the subtropical NE Atlantic
  • Analyses of cold-water coral habitats on seamounts and their climate-induced temporal development
  • Analyses of geochemical trace elements to determine the origin of water masses, their ventilation in the subtropical Atlantic to assess the influence of the water-sediment-interface
