Objective

The MoMARSAT2018 cruise on the Atalante will gather 2 projects:

  • The yearly maintenance cruise of the EMSO Azores deep-sea observatory on the Lucky Strike hydrothermal vent field (PI PM Sarradin),
  • LUCKYDIVMIC

The 2 projects are presented thereafter.

 

EMSO-Azores

Hydrothermal circulation at mid-ocean ridges is a fundamental process that impacts the transfer of energy and matter from the interior of the Earth to the crust, hydrosphere and biosphere. The unique faunal communities that develop near these vents are sustained by chemosynthetic microorganisms that use the hot fluid chemicals as a source of energy. Environmental instability resulting from active mid-ocean ridge processes create changes in the flux, composition and temperature of emitted hydrothermal fluids and influence the hydrothermal communities.

The MoMAR (Monitoring the Mid-Atlantic Ridge) project was initiated 20 years ago by the InterRidge Program to promote and coordinate long-term multidisciplinary monitoring of hydrothermal vents at MAR. It aims at studying vent environmental dynamics from geophysics to microbiology.

The EMSO-Azores observatory at Lucky Strike has first been deployed in 2010. It is primarily directed at understanding a mid-ocean ridge black smoker's hydrothermal system, from the magma chamber that supplies the heat, to the microhabitats that host the hydrothermal fauna, and to the hydrothermal plume in the water column. The maintenance procedure is performed every year and requires the use of a Remotely Operated Vehicle. It includes recovery of seafloor instruments and moorings, full onboard checkup and repairs of each component, and redeployment. In addition, we perform yearly sampling of fluids and fauna, and capture videos of vents and habitats that provide critical background to instrumental time-series data. The Lucky Strike hydrothermal field is located in the center of one of the most volcanically active segment of the MAR. This monitoring offers a high probability of capturing evidence for volcanic events, observing interactions between faulting, magmatism; hydrothermal circulations and, evaluating their impacts on the ecosystem.

The Momarsat cruise concerns the yearly maintenance of the EMSO-Azores observatory at Lucky Strike (Mid-Atlantic Ridge). In its actual configuration after the 2016 maintenance cruise, The observatory infrastructure is composed of two Sea Monitoring Nodes (SEAMON) acoustically linked to a surface relay buoy (BOREL), ensuring satellite communication to the land base station in Brest.

The first node dedicated to large scale geophysical studies is moored in the center of the fossil lava lake characteristic of the Lucky Strike vent field. This node hosts an Ocean Bottom Seismometer (OBS) and a permanent pressure gauge (JPP). The second node is deployed at the base of the Tour Eiffel active edifice to study the links between faunal dynamics and physico-chemical factors. This node is composed of a HD video camera, 4 LED lights, an Aanderaa optode, an in situ chemical analyser and an instrumented microbial colonization device. The observatory infrastructure was enriched in 2016 with a 70 m long thermistor chain with 100 sensors deployed around Tour Eiffel, a Chlorinity sensor (BARS) deployed in the Aisics hot vent, and 4 Ocean Bottom Hydrophones (Hydroctopus) forming an array with 70 m aperture.

Scientific and technical data (including a snapshot) are transmitted daily to the Data Centre in Brest (scientific and technical data). Data are available online - http://wwz.ifremer.fr/emso-france/EMSO-Azores according to European directives.

The MoMARSAT experimental design also includes autonomous instruments such as 4 OBS, an oceanographic mooring and temperature probe array. Site studies including video surveys, sampling (rocks, water and organisms), and colonization experiments are also performed during the cruises. In 2016, an oceanographic mooring (DEEPCORR) to study corrosion processes in deep marine environment was deployed in the area in the framework of the FIXO3 EU project.

The general objective of this cruise in 2017 is to maintain the observatory infrastructure and to continue the experimental design. In the framework of the French ANR project Luckyscales, a specific objective in 2017 is to implement a new hot fluid sampler. The DEEPCORR mooring will be also recovered.

A specific sampling program will be focused on the crab Segonzacia mesatlantica and the shrimps Mirocaris fortunata. The specimens will be maintained alive in specific aquaria and will be provided to Oceanopolis in Brest for the "Abyss box" exhibition, done in collaboration between Oceanopolis, Univ. Paris Sorbonne (UPMC) and Ifremer, and involving IMAR DOP since 2012.

The team involves personnel from Ifremer (REM RDT, GM and EEP), 5 CNRS-INSU laboratories (IPGP, LOPS, OMP-GET, LEMAR, et LIENs-la Rochelle), 2 Portuguese universities (Université des Açores et Université de Lisbonne). German (Université de Brême) and US colleagues (Woods Hole Oceanographic Institution and Université de Washington à Seattle) are also associated.

The study area belongs to the Portuguese ZEE and is included in an OSPAR Marine Protected Area.

This project is related to the following European projects:

  • FIXO3 (Fixed Point Open Ocean Observatory Network, www.fixo3.eu/, coordination R. Lampitt - NERC)
  • EMSO (European Multidisciplinary Sea Observatory, www.emso-eu.org/, P. Favali - INGV).

 

LUCKYDIVMIC

The aim of the LuckyDivMic cruise is to continue the  sampling of hydrothermal chimneys in a more accurate way andbased on the experience gained from previous MoMARSAT cruises. Sampling of a hydrothermal chimneys, associated fluid, and collection of particles in the mixing gradient should be done in a single sequence, and that takes about 3 hours of work using the ROV Victor. If the previous MoMARSAT cruises it was made possible to carry out some of these samping,  but some sites could not be sampled.

Our sampling capacity at the bottom with Victor (number of sampling box and titanium syringes, number of pouches available on the PEPITO sampler and our on-board sample processing capacity (grinding of chimneys in anaerobic chamber, conditioning of fluids, etc. ...) make difficult to carry out all the sampling and preservation of the samples  during the same dive.
