The cruise's objective was to perform the annual maintenance of the seafloor observatory set up on the Lucky Strike hydrothermal field during the MoMARSAT 201O cruise. This observatory, which can transmit its data in near real time via acoustic then Hertzian channels, is once of the nodes in the EMSO (European Multidisciplinary Seafloor and water column Observatory) network. Its objective is to study over the long-term of active processes linked to seismicity, volcanism and hydrothermalism of the Mid-Atlantic Ridge and associated ecosystems. It includes both an infrastructure for data transmission (SEAMON stations on seafloor and BOREL surface buoy) and a set of sensors (geophysics, chemistry, physics, oceanography and biology). Some sensors are connected to the SEAMON stations and communicate all or part of their data towards shore every 6 hours, while the others are autonomous and store their data inside. Along with the observatory's technical maintenance, the second objective of MoMARSAT2013 was to acquire measurements and spot observations on the Lucky Strike field in order to validate the time-series data, extend the range of parameters studied and improve the spatial resolution of the study. The related projects are EMSO, FIXO3, ANR Luckyscale.
