The Institute

Ifremer, a French ocean-science research institute, leads research and expert assessment projects on the oceans and their resources, monitoring marine and coastal environments to foster sustainable development of marine activities.

Ifremer harbours a wide range of scientific disciplines and expertise and is the only structure of its kind in Europe.

Founded in 1984, Ifremer is a French public entity of industrial and commercial nature. It comes under the joint authority of the Ministries of Higher Education & Research, Ecology, Sustainable Development & Energy and Food and Agriculture.

The Institute is structured in four main components:

  • Four scientific and technology departments;
  • Five operations and scientific support divisions (Human Resources; Financial & Legal Affairs; Innovation; Communication; European and International affairs) and an accounting agency;
  • 5 national centres (English Channel-North Sea, Brittany, Atlantic, Mediterranean and Pacific Centres)
  • Management of the French research infrastructure fleet

Ifremer has a current workforce of 1500.

Job description and lab:

The Geochemical Cycles and Resources laboratory (LCG) conducts leading research on the processes of the genesis, transport and transformation of chemical species in varied geological ocean systems extending from continental margin cold seep zones through back-arc basins and abyssal plains to seafloor hydrothermal systems of oceanic ridges and seamounts. The research activities are centered around the mobilization and transport of metals by hydrothermal fluids and their dispersion in the water column, on the deep carbon cycle and biogeochemical interactions, and the formation and evolution of hydrothermal vents and massive sulphide deposits.

The successful applicant, specialized in hydrothermal fluid geochemistry, will reinforce our expertise in fluid studies to gain understanding in metal, carbon and biogeochemical cycles.

He/She will work within the LCG laboratory and conduct research projects on the circulation of fluids and fundamental exchange processes between the ocean, the deep biosphere and volcanic, mantellic and sedimentary substrates.

He/She will provide expertise in the fields of inorganic and organic geochemistry of active vent and seep sites in contrasting geological environments. He/She will take part in ocean-going research expeditions, and study the geochemistry and thermodynamics of hydrothermal fluids, identifying the transfer mechanisms of inorganic and organic elements, particularly metals, organo-metallic chemicals and gases to gain understanding on heat and matter exchange between the lithosphere and the ocean, the formation of metal deposits and chemical transfer to the water column.

He/She will play a key role in acquiring and processing data from chemical analyses obtained on-board or in lab and in particular those pertaining to the study of volatiles (e.g. hydrogen, methane) and organic compounds. Building on an integrated approach, he/she will play a proactive role in understanding the phenomena of hydrothermal contexts and will work in close collaboration with the team's researchers, engineers and technicians specialized in sensor technology and on-board scientific equipment development. He/She will contribute to the development of at-sea or in lab chemical analysis methods to perform his/her functions and to achieve set objectives. The profile sought requires top-level technical and analytical skills and expertise in the field of multiple-source data integration (multi-scale and multi-technique).

Main objectives

  • He/She will take part in developing our expertise in the field of hydrothermal fluids by contributing to studies concentrating on hydrothermal systems in the mantellic and back-arc domains.
  • He/She will contribute to and lead new projects on ocean hydrothermal venting and its impact on biogeochemical cycles.
  • He/She will play an active part in seafloor exploration of new hydrothermal vent sites.
  • He/She will applied available state-of-the-art geochemical analysis adapted to hydrothermal vent studies and shall contribute to the development of new techniques as appropriate (e.g. GC-MS, FIA, ICP-MS).

Main activities

  • He/She will activity contribute to the study of deep-sea hydrothermal processes and interactions and their impact on ocean biochemistry.
  • He/She will take part in and/or take charge of ocean-going expeditions lead by IFREMER as part of fundamental research or as support for public authorities (e.g. REMIMA).
  • He/She will develop externally-funded collaborative scientific projects
  • He/She will have the capacity to mentor students at all levels including post-docs, to publish scientific articles and to reply to calls for projects.
  • He/She will develop analytical methodologies adapted to hydrothermal seep studies using tools available in the lab.

Collaboration spheres:

In-house: The research units of REM department: the Marine Geosciences Unit (GM), the Deep-Sea Ecosystems research unit (EP), the Technological Research and Development unit (RDT)

External: National (universities, research institutes, etc.), international and industrial collaboration.

Required training and experience

  • PhD
  • Excellent level of training and expertise in solution chemistry.
  • Academic or professional experience in the field.
  • Thorough understanding of analytic methods and techniques of chemical data processing.
  • Geological knowledge.
  • Excellent written and spoken command of English.
  • Experience in sea-going expeditions.
  • Capacity for collaborative work and a strong sense of initiative (cruise application, ANR-funded projects, European projects).
  • Experience in top-level scientific publication.

Personal skills:

  • Strong sense of responsibility, team-spirt and autonomy.
  • Taste for analytical methods and an integrative approach in addressing topical issues.
  • Fit and motivated for ocean-going expeditions.
  • Motivation for interdisciplinary research.
