Researcher Carbon Biogeochemistry M - F H/F - Ifremer

Join Ifremer, an ally of planetary well-being, to gain a better understanding of and better protection for the ocean.

From the abyss to the surface, from the coast to the open SEA, Ifremer is the French research institute that is wholly dedicated to the Ocean. Its teams carry out research, innovate and produce expert reports to protect the ocean, exploit its resources in a responsible manner and shares marine data.

Ifremer contributes its scientific expertise to throw light on public policies and develops solutions drawn from the ocean to meet the challenges of the ecological transition. Ifremer is the operator of France's oceanographic fleet with its shipbuilding subsidiary Genavir, and imagines, designs and deploys leading edge technological means to solve the ocean's mysteries.

Join our teams, made up of 1500 scientists and research support staff, present all along the coastal areas of France and French overseas territories.

Who are we?

The Ifremer Environment and Resources Laboratory of the Pertuis Charentais (LER/PC) is located in La Tremblade in the Nouvelle-Aquitaine region. It belongs to the Observation and Ecology of Coastal Ecosystem Restoration Unit (COAST) of Ifremer's Oceanography and Ecosystem Dynamics Department (ODE), and is attached to Ifremer Atlantic Centre. Its activities are divided into three main areas:

(i) monitoring and observation of marine water quality and coastal ecosystems;

(ii) providing expertise in its field of competence to local authorities, public policies, professional organizations and issuing opinions to ministries and decentralized departments;

(iii) conducting research in direct response to marine social and economic issues at regional, national, and international levels.

Within the ODE Department and the COAST Unit, the position located in La Tremblade, reports to the LER/PC Manager. The Researcher will work in collaboration with technicians, engineers, and researchers from the LER/PC and more broadly from Ifremer and its scientific partners.

What will your mission BE?

The scientific activity of the LER/PC is based on the understanding of the functioning and evolutionary trajectories of coastal ecosystems in the face of the multiple pressures they are subjected to and, more specifically at the laboratory, on carbon processes and fluxes at land - coastal zone - atmosphere exchange interfaces.

In a context of Global Change and increasing greenhouse gases, the role played by coastal ecosystems in regional and global carbon budgets and associated atmospheric exchanges, is a major issue in climate change mitigation. Carbon dynamics controlled by specific and complex biogeochemical factors and processes at different interfaces and time scales characteristic of the coastal zone, raises biogeochemical and functional questions that require an interdisciplinary approach combining coastal biogeochemistry, statistical tools and modeling.

As a Researcher, the recruited person will be responsible for participating in the COAST Unit's research and innovation work on carbon processes and fluxes at land-coastal zone-atmosphere exchange interfaces, in different typologies of coastal systems including salt marshes, seagrass beds and reefs. He/she will contribute to the implementation of integrated approaches in the field and in the laboratory to characterize the physicochemical and biological processes reflecting fluxes at the land-coastal zone-atmosphere interfaces in the context of Climate Change. Emphasis will be placed on i) the study of the spatiotemporal dynamics of large-scale atmospheric carbon (CO2 and CH4) exchanges and associated controlling factors, ii) carbon form dynamics in coastal water masses in terms of processes, fluxes, management and biodiversity associated with different time scales and iii) the formulation of integrated carbon budgets at land - coastal zone - atmosphere interfaces and the evaluation of certain coastal ecosystems known as Blue Carbon as Nature-Based Solutions in the fight against biodiversity loss and Climate Change.

What will your activities BE?

- Lead and coordinate research projects related to processes/fluxes at the land-coastal zone-atmosphere exchange interfaces, within the framework of regional, national, and European projects in conjunction with other units of the institute.

- Contribute to the LER/PC and COAST Unit's activities supporting public coastal zone management policies and expertise on the topic of carbon processes/fluxes.

- Ensure the dissemination of knowledge to the scientific community, coastal managers, and public policies.

- Participate in research training by supervising students (Master and PhD students) and supporting postdoctoral fellows and technical staff.

- Develop and propose "Carbon Indicators" to scientists, managers, and public policies to characterize the environment state.

How are your activities organised ?

- Employment rate: full-time
- Occasional at-sea missions aboard small boats, coastal, and offshore research vessels
- Prolonged screen work

Who are you?

Training: PhD and post-doctorates in carbon biogeochemistry with expertise in processes/fluxes at land - coastal zone - atmosphere exchange interfaces.

You have the following skills, knowledge and experience:

- Proven experience in carbon biogeochemistry in coastal systems, and proficiency in in situ and laboratory measurement methods used in biogeochemistry and interface flux studies.

- Proficiency in statistical and modeling tools adapted to qualify and quantify carbon flux data sets and associated biogeochemical parameters. Skills in processing long, multi-year time series are a plus.

- Professional experience (postdoctoral) within recognized universities and/or research institutes in the field is an asset for the position.
