Research position in hydrothermal fluid geochemistry
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:
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).
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)
