Offer Description

The laboratory

LIENSs is an Interdisciplinary Joint Research Unit jointly operated by the French National Centre for Scientific Research (CNRS) and La Rochelle University. The laboratory focuses on the sustainability of coastal environments, which are increasingly vulnerable to the impacts of climate change and human activities. It brings together around 80 researchers, 29 permanent engineers and technicians, 24 postdoctoral and visiting researchers, and 40 doctoral students.

The project

The primary goal of this project is to investigate the impacts of terrestrial freshwater and organic/inorganic matter fluxes delivered through rivers on the evolution of shallow coastal ecosystems and sediments. These systems are strongly affected by human activities. In particular, the study aims to elucidate how such transformations influence the coastal carbon cycle and the exchange of CO2 between the atmosphere and the ocean in the shallow waters of the Bay of Biscay, located in the northeastern Atlantic.

We are seeking a highly motivated early-career researcher to contribute to the development of a regional, high‑resolution (80 m) configuration of the global ECCO‑Darwin model (Carroll et al., 2020; www.ecco-group.org ; https://darwinproject.mit.edu). The selected candidate will refine the physical processes represented in the regional model, with particular attention to improving land–sea coupling and sediment–water interactions. Building on recent progress in both regional (Bertin et al., 2025) and global (van der Zant et al., 2025) ECCO‑Darwin configurations, the candidate will play a key role in advancing understanding of coastal biogeochemical dynamics.

The position offers the opportunity to collaborate with a dynamic, international team of researchers and to take part in both national and international research initiatives.
