| Abstract | During the cruise MSM10/3 bathymetric mapping was conducted to yield the region albathymetry in the vicinity of the Logatchev hydrothermal vent field. Further, mapping operation was scheduled for night operation and times when it was not possible to handle any other equipment, for example during bad weather conditions. Overall, the mapping program was successful, providing a detailed high-resolution map of the area. Interestingly, the Logatchev field is located to the east of the neovolcanic zone and hence off-axis. Further, bathymetric mapping suggested that at the latitude of the vent field, spreading caused a highly asymmetric structure of the median valley and flanking rift mountains with profoundly higher elevations on the eastern African plate. |
