After the exploration of shallow hydrothermal vents in the waters south of the Greek island of Milos during leg 1 of cruise M192 (led by Dr. Solveig Bühring from MARUM), leg 2 is dedicated to diving down to the discovered sites and sampling of fluids, gas, rocks and biota with the remotely operated vehicle (ROV) SQUID from MARUM. Our team is already working on hydrothermal fluid samples recovered during the first successful dives, eliciting the secrets of hydrothermal processes at the seafloor from its chemical composition.
During the first leg of research cruise M192, an autonomous underwater vehicle (AUV) will be used for mapping and exploration to locate hydrothermal vent systems off Milos in the mediterranean Sea that will be investigated in more detail during the second leg of the cruise.
Our project within the SPP will investigate the role of environmental conditions for hydrothermal metal transport and ore formation. We will study the impact of pressure and temperature, type of host rock, boiling and phase separation as well as of organic compounds on metal mobility and metal sulfide deposition during field studies in hydrothermal vent areas and in lab experiments.
