“Research Scientist position in biostratigraphy (H/F)
Location: Centre de Bretagne – Brest, Ifremer/ REM/ UGM/ LGS, The Laboratory of Geodynamic and Sedimentary environment, French Brittany Center, Brest, France
Deadline for applications: 15 May, 2017
Contract type: Poste vacant
Date of function: Dès que possible
Working conditions: Full-Time
French Research Institute for Exploitation of the Sea, Ifremer, through its research work and expert advice, contributes to the knowledge of the oceans and their resources, the monitoring of marine and coastal environments and the sustainable development of marine activities. To these ends, Ifremer conceives and operates tools for observation, experimentation and monitoring, and manage the oceanographic databases.
Created in 1984, Ifremer is a French public institute of an industrial and commercial nature. It is supervised jointly by the Ministry of Higher Education and Research and the Ministry of the Environment, Energy and Marine Affairs.
The Laboratory of Geodynamic and Sedimentary environment within the Marine Geoscience research unit leads fundamental and applied research on continental margins and their sedimentary filling, from the initiation of rifts and the opening of ocean basins up to their latest stages of filling (ie. Holocene). The laboratory relies on the acquisition and interpretation of geological, sedimentological, geochemical and geophysical data. Its holistic approach aims at a multidisciplinary interpretation of the architecture of basins and their relations with external geodynamic and climatic factors at different time and spatial scales in order to elaborate stratigraphic and geodynamic models.
The «Marine Geosciences» (GM) Research Unit at Ifremer is one of the oldest of the institute. Since its creation, GM has improved its performances in fundamental and applied scientific research at an international level in nearly all domains of marine geosciences. The Laboratory of Geodynamics and Sedimentary recording (LGS), is one of the 3 research laboratories of GM. The LGS aims to develop its expertise in decrypting the recording of paleo-environmental fluctuations (continental and oceanographic) in marine sediments in order to understand their role as a forcing factor in earth-ocean sedimentary transfer, deposit processes, sedimentary building of margins and geological hazards. The objectives are to determine the modification of sedimentary input and deposition in relation with the source (silicoclastic, carbonate, terrigenous, biogenic, organic), paleo-oceanographic conditions and also in situ factors such as fluid circulation and the presence of methane and gas hydrates. Another objective is to provide the chronological constraints necessary to elaborate a chronostratigraphical model and to understand the evolution of deposit environments.
We seek a geologist specialized in the micropaleontology and ecology of benthic and planktonic foraminifera who will join a multidisciplinary team of geodynamic/tectonic experts and sedimentologists. The reconstruction of paleo-biotopes will be approached using foraminifera as (1) a tracer of sedimentary and organic input modifications (2) geochemical/biological modifications linked to paleo-environmental fluctuations (3) and as the chronological constraint necessary for the understanding of stratigraphic, lithological and paleo-environmental models. Competence and experience will be required for the acquisition and interpretation of geochemical recordings contained in foraminifera tests such as the paleo-temperature, paleo-salinity, paleo-hydrogeneous potential recorded by stable isotopes and/or trace metals. Competence and experience in the study of diverse oceanic sedimentary studies is strongly sought.
He/she will lead research in the reconstruction of marine paleo-biotopes and the characterization of paleo-environments deposits in relation to the evolution of global factors.
He/she will contribute to the on-going research projects of the LGS and also to those of the “Sedi-ment Dynamics and Geohazards » laboratory (LAD) by joining a multi-disciplinary team of specialists in geodynamics/tectonics and sedimentologists. His/her contribution will be based on the determination of faunistic assemblages, and complementary environmental constraints (e.g. paleoT°C, paleosalinity, etc.) obtained directly via the geochemical analysis (stable isotopes, trace metal, etc.) of foraminifera tests. He/she will develop original research projects in relation with the topics of the LGS and the LAD, to include coastal and ocean-going expeditions within public, private, regional, national and international cooperation.
He/she will publish the results of the research in high-impact scientific journals.
Collaborative work environment
• He/she will contribute to the multi-parameter approach of LGS (cores and seismics) by integrating methods of sedimentology, chronostratigraphy, micropaleontology and geochemistry. He/she will participate in the interpretation of marine sedimentary recordings in a regional context (hemipelagic, turbiditic, contouritic sedimentation…) and in a global context according to internal and external forcings (eustatic, climatic, paleoceanographic…) and in the quantification of the dynamics of earth-ocean transfers.
• He/she will also participate in the development of tools of analysis and interpretation.
• In the case of multi-disciplinary projects on habitats/ecosystems and benthic ecology on continental margins, he/she will develop/maintain relations/collaborations with the research unit Deep-Sea Ecosystems.
• He/she will be involved in Ifremer research projects within national, European and international scientific cooperation and also with industrial partners.
Profile and expertise sought
PhD in the field of marine geosciences, marine paleo-environment, paleo-oceanography.
