Cold-Water Coral Ecosystems of the Azores
Atlantic Thermocline Ocean and Ecosystems Dynamic during Natural Climate Change
- ROV Test-Dive: 06. - 07. October 2018
- Expedition: 08. - 31. October 2018
- Ponta Delgada (Azoren) - Funchal (Madeira)
- Seamounts south of the Azoren (SE Atlantic)
Working Area
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
