The Expedition PS119 Punta Arenas - Port Stanley
During R/V POLARSTERN cruise PS119 we are planning to investigate hydrothermal vents and potential cold seeps at the Sandwich micro-plate using the remotely operated vehicle (ROV) MARUM-QUEST. The planned research is based on the discovery of unique hydrothermal vent ecosystems at the back-arc spreading East Scotia Ridge as well as at submarine volcanoes of the South Sandwich Island Arc. The overarching theme of the project is to study in a comparative way the geological settings of geofuel emissions at the seafloor with their associated ecological hot spots. In a cross-disciplinary approach, we intend to study aspects of geology, geochemistry, microbiology, symbiont-host relationships as well as eukaryotic biogeography in an international research consortium combining experts in their respective field of sciences. Addition investigations of the South Sandwich volcanoes as well as the distribution of wales are further topics of the research cruise PS119.
