Marine Ecosystem Engineers Long-Term Evolution ModelING in resPOnse to climate change and sediment Transport in Seine EStuary

Abstract

The doctoral project is to determine the optimal physical conditions for six species among the benthic fauna found in the Seine estuary, using the MARS3D physical model from IFREMER and biological data collected since 1990.

In parallel, bioturbation models of the same species will be developed in order to be able to translate the effect of fauna on the evolution of the sediment (erosion / accretion) in the MARS3D model.

The ultimate objective being to be able to spatially and temporally model the habitats of the species chosen via MARS3D, in order to be able to assess their evolution under future conditions, in 2050-2100, corresponding to the scenarios of the IPCC and thus assess the future of the ecosystems of the estuary.
