Objective The MoMARSAT cruise ensure annual maintenance of the EMSO-Azores observatory in the Lucky Strike hydrothermal field. This seafloor observatory has been operated since 2010 and aims to acquire >=10 years of time series on hydrothermal, tectonic and volcanic processes and the ecosystems of an active hydrothermal site on the Mid-Atlantic Ridge. It is part of the European EMSO (European Multidisciplinary Seafloor and water column Observatory) network, supported in France by the EMSO-FR MESR infrastructure which is led by Ifremer-CNRS collaboration and which is a component of the European FIXO3 Fixed point Open Ocean Observatory network. The array has an observatory infrastructure stricto sensu: a buoy (BOREL) providing data transfer to a server on shore as well as communications with connected instruments, and two junction boxes (SEAMON) on the seabed which communicate acoustically with the surface buoy. The instruments are connected to these junction boxes. The array also includes autonomous instruments providing internal data storage. In its current configuration (after MOMARSAT 2017 maintenance) the observatory comprises a connected seismometer (OBS), a connected bottom pressure probe, a connected biological observation module (TEMPO - with an HDTV video camera and 4 projectors, temperature, oxygen, dissolved iron and turbidity sensors), 20 autonomous temperature probes for hydrothermal fluids and mixing zones, 3 autonomous current-meters set on the seabed, 1 generic EGIM module, 1 array of 4 hydrophones (Hydroctopus), 1 temperature and chlorinity sensor, 4 microbiological colonization units and an oceanographic mooring. The 2017 cruise also made it possible to change the BOREL buoy in place since the beginning of the experiment (and whose mooring broke in April 2017) and to deploy a brand new autonomous prototype for sequential sampling of hydrothermal fluids (DEAFS). In-situ measurements as well as fluid and biological samples were taken to complement the set of parameters and integrate a spatial component at each maintenance operation. This year two significant experiments were also carried out: one experiment for a chronobiological study in the Bathymodiolus azoricus horse mussel and another to study the restoration of assemblages of this horse mussel after disturbance. Maintenance operations included retrieving the BOREL-SEAMON infrastructure and connected instruments, reconditioning them on board, then redeploying them. Recovery and redeployment of autonomous instruments are done either during the ROV inter-dives for the oceanographic mooring or on dedicated ROV dives for other sensors and sampling. Experience gained from previous maintenance enabled an optimised cruise strategy to be proposed for 15 to 17 days in the zone, taking account of possible technical and meteorological hazards. There are 31 people on the maintenance team, including 10 staff for the BOREL and SEAMON infrastructure and sensors and 21 scientific staff to operate the sensors and coordinate sampling. Coordination of maintenance operations and the initial use of data is ensured by Mathilde Cannat. Operations on board were led by two of the four experienced co-head scientists mobilised for the project (Pierre Marie Sarradin, Jérôme Blandin, Mathilde Cannat and Javier Escartin). Satellite-transmitted data are immediately available on an EMSO server (http://www.emso-fr.org). The team involves Ifremer (REM RTD and EEP), 5 INSU laboratories (IPGP, LOPS, OMP-GET, IUEM, and LIENs-la Rochelle), two Portuguese entities (University of Azores and University of Lisbon), and colleagues from the University of Washington in Seattle and the University of Bergen. The study zone is part of Portugal's EEZ and a "Marine Protected Area" (OSPAR). On this year's cruise, a team of artists and video makers took part in the framework of the Deep thoughts "arts and sciences" project whose objective is to create collaborative work between artists and scientist for a show on deep sea environments in 2019. The ship's log for the cruise was published on this project's blog (donvor.blog).
