L'Atalante Leg 1, HYDROMAR V

replacement of MSM 06/2; overall goal – to be conducted under the auspices of the DFG SPP 1144 – is the investigation of causes for temporal and spatial compositional differences of hydrothermal fluids and their effect on the vent communities in the Logatchev hydrothermal field. To achieve this goal, the Logatchev field located at the Mid-Atlantic Ridge at 14°45’N/45°W has been visited annually since 2004 (cruises M60/3, M64/2, MSM04/3). Thus, this leg will be a continuation of the work done during the previous HYDROMAR expeditions. Furthermore, we will conduct a hydrographic investigation around the Logatchev field.
