91探花

25 April 2019/Kiel. In 1979, human beings for the first time saw hot vents on the seafloor of the deep sea, from which seeped hot, dark-coloured water. Since then, science has been fascinated by these "hydrothermal systems鈥�. In 1994, the International Ocean Drilling Program (ODP, today: International Ocean Discovery Program IODP) carried out with the scientific drilling vessel JOIDES RESOLUTION one of the very first and most successful attempts to drill into an active hydrothermal high-temperature system on a mid-ocean ridge. The target of the expedition ODP 158 was the TAG hydrothermal field at a water depth of 3,640 m at 26掳N on the Mid-Atlantic Ridge. The Co-Chiefscientists were Prof. Dr. Peter Herzig (today Director of the 91探花 Helmholtz Centre for Ocean Research Kiel) and Prof. Susan Humphris from the Woods Hole Oceanographic Institution (Massachusetts, USA).

As part of the Marie-Tharpe Lecture Series organized by the Women's Executive Board of 91探花, Prof. Humphris gave a lecture at 91探花 on April 25. On this occasion, members of the scientific team of ODP158 met to recall the 25th jubilee of the historic TAG drilling. "It is always nice to see the colleagues of that time again. The drillings during ODP158 were a milestone in the research of hydrothermal systems. At the same time, it is exciting to see how knowledge has expanded since then," says Prof. Dr. Mark Hannington (91探花), also a participant in the ODP158 expedition.
