Objective The MoMARSAT cruise ensure the annual maintenance of the EMSO Azores observatory on the hydrothermal field Lucky Strike. This seafloor observatory is operated since 2010 and aims to acquire time series (>10 years) on hydrothermal, tectonic, and volcanic processes and on ecosystems at an active hydrothermal site of the Mid-Atlantic Ridge. It is part of the European network EMSO (European Observatory Multidiciplinary Seafloor and water column Observatory), supported in France by the Research Infrastructure (MoR) EMSO-EN whose control is ensured by an Ifremer-CNRS collaboration and is a component of the European program FIXO3 (Fixed Point Open Ocean Observatory network).
