Description du poste

Postdoctoral Research Associate In Mineralogy And Marine Geochemistry M - F H/F

The UMR Geo-Ocean (www.geo-ocean.fr) is a joint research unit in marine geosciences, involving Ifremer, CNRS (mainly INSU), the University of Brest (UBO), and the University of South Brittany (UBS). Its multidisciplinary focus includes geology, geophysics, geochemistry, sedimentology, and cartography, covering processes shaping the earth from past to present, from coast to deep sea. The Geo-Ocean and its Biogeochemical Cycles and Resources (CYBER) team contribute to understanding the deep sea, a priority of the Institute and the department (Physical Resources and Ecosystems of the Deep Sea - REM).

The CYBER team studies matter and energy exchange between the oceanic lithosphere and hydrosphere through geological, geochemical, and numerical approaches, focusing on fluxes, transfer mechanisms, and the formation of deep-sea resources like minerals and natural hydrogen. The team also investigates biogeochemical cycles of the deep ocean and ancient Earth, developing in situ and ex situ physicochemical measurements and new biogeochemical tracers.

General responsibilities

This postdoctoral position is part of the LIFEDEEPER Priority Research Program, funded by the French National Research Agency (ANR), focusing on deep-sea ecosystems' vulnerability to mineral resource exploitation. It also supports the REMIMA project on deep-sea mineral resources, utilizing data from HERMINE cruises under the International Seabed Authority agreement.

The successful candidate will be supervised by Dr. Ewan Pelleter and Dr. Olivier Rouxel, primarily based at Ifremer Bretagne Center (Plouzané, Finistère). The role involves working on low-temperature mineralization samples from oceanographic expeditions, mainly in the TAG hydrothermal field, using data from previous analyses (XRF, XRD, ICPMS) to perform mineralogical and isotopic studies (Cu, Ni). The goal is to better understand metal mobilization, remobilization, and trapping during seafloor deposit maturation, collaborating closely with CYBER researchers and microbiologists from UMR BEEP.

You should have expertise in mineralogy and geochemistry, including analytical techniques, with knowledge of hydrothermal systems and Fe-Mn-Si mineralization being advantageous. Responsibilities include:

• Mineralogical analysis of Fe-Mn-Si mineralization (optical microscopy, RAMAN, µ-XRD)
• Elemental geochemical analysis (SEM-EDS, electron probes)
• Cu and Ni isotopic analysis via microdrilling
• Publishing results in peer-reviewed journals

Qualifications

• Ph.D. in geosciences (obtained within the last 3 years)
• Experience in mineralogy and/or metallogeny
• Expertise in isotopic geochemistry
• Knowledge of hydrothermal systems
• Research record demonstrating publication in international journals

Personal qualities

• Enthusiasm, drive, rigor, perseverance, autonomy
• Open-mindedness, interpersonal skills
• Ability to work in a team and at sea
• Scientific curiosity, adaptability, mentorship skills
• Ability to synthesize and communicate results effectively

Join Ifremer to contribute to ocean understanding and protection, working across various marine environments, from the deep abyss to coastal areas.

Working conditions

• 18-month fixed-term contract
• Full-time position
• Possibility of onboard expeditions
