The Institute and the recruiting departement

A pioneer in ocean science, IFREMER’s cutting-edge research is grounded in sustainable development and open science. Our vision is to advance science, expertise and innovation to:

- Protect and restore the ocean

- Sustainably use marine resources to benefit society

- Create and share ocean data, information & knowledge.

With more than 1,500 personnel spread along the French coastline in more than 20 sites, the Institute explores the 3 great oceans: the Indian, Atlantic and Pacific oceans. A leader in ocean science, IFREMER is managing the French Oceanographic Fleet and its dedicated scientists create ground-breaking technology to push the boundaries of ocean exploration and knowledge, from the abyss to the atmosphere-ocean interface.

Well-established in the international scientific community, our scientists, engineers and technicians are committed to advance knowledge about our planet’s last unexplored frontiers. They provide the science we need for informed decision-making and public policy and they transfer this knowledge and technology to businesses to fulfill public and private needs. Core to our mission is also to strengthen public awareness about the importance of understanding the ocean and its resources, and empowering future generations of leaders through education and outreach national campaigns.

Founded in 1984, IFREMER is a French public organization and its budget approximates 240 million euros. It is operating under the joint authority of the French Ministry for Higher Education, Research and Innovation, the French Ministry for the Ecological and Solidary Transition, and the French Ministry of Agriculture and Food.


General areas of responsibility

  • Presentation of the department, research unit or laboratory

The DYNECO (Dynamics of Coastal Ecosystems) research unit is one component of the “Oceanography and Ecosystems Dynamics” department. Its main objective is to study how coastal ecosystems respond to anthropogenic or natural pressures. DYNECO conducts scientific and expert assessment activities in this field. The global approach rests on the analysis of physical and biogeochemical processes and is based on experimentations, in-situ observations and modelling. The main research areas concern: i) dissolved and particulate matter fluxes within marine coastal ecosystems, ii) diversity, functioning and future of communities and of their habitats, iii) perturbation at population scale.

Within DYNECO unit, the Hydro-Sedimentary Dynamics laboratory (DHYSED) studies the hydrodynamic processes and sediment dynamics at different spatial scales (French coasts, bays and estuaries) and time scales (from tidal up to multi-decadal scales). The DHYSED laboratory develops of MUSTANG sediment transport numerical model, coupled to various hydrodynamics cores (MARS3D, SYMPHONIE, ROMS/CROCO).

  • Introducing the job description, indicating the work position in the organizational chart:

The successful candidate will study the sediment dynamics of the Bay of Biscay. He/she will be in charge of producing a 20-year hindcast of the sediment dynamics in the Bay of Biscay with the CROCO/MUSTANG model. Using this hindcast, together with in situ and ocean color data, he/she will focus on the relation between sediment dynamics and forcing (including storms) at the inter-annual timescale.

He/she will be under the hierarchical responsibility of the head of DHYSED laboratory.

General areas of responsibility (principal missions)

He/she will contribute to set up and evaluate a sediment dynamics model in the Bay of Biscay, analyze the results, and publish the outcome of the study in peer-reviewed publications.

Principal activities

He/she will be more specifically in charge of:

  1. Calibrating and analyzing the turbidity data from 4 continuous moorings (starting in 2017) in South Brittany and 2 dedicated field campaigns. The objective will be to provide a dataset to help the numerical model validation.
  2. Analyzing satellite ocean colour data from 1997 onwards to quantify the interannual variability of surface TSS and support the model validation.
  3. Setting up the CROCO/MUSTANG model of the Bay of Biscay, producing a 20-year hindcast, and evaluating this hindcast.
  4. Assessing the interannual variability of sediment fluxes in the Bay of Biscay shelf, based on the previous tasks.
