One year postdoc position
Multi-scale analysis of turbulence and turbidity couplings in coastal environments
• Description of the project
Sediments suspension processes in coastal zones is a complex subject which has not been fully studied and understood, due to the fact that the processes involved are high frequency and are not easy to sample using classical approaches. It is proposed here to analyze the link between turbulence level –directly linked to physical forcing by wind or tides – and the concentration and nature of the materials in suspension. For this, velocity time series and vertical profiles will be recorded using high frequency current meters, simultaneously with optical measurements providing scattering and backscattering of marine particles. The latter are directly linked to the nature and concentration of particles.
This study will be performed using in situ measurements in the Eastern English channel under different conditions of wind and tides; and also in other sties characterized by different types of bottom (sand or mud). This will be done in collaboration with engineers and researchers of the team. Collaborations with geologists and marine biologists of the laboratory are also expected, to characterize the type of the bottom and to work on links with primary production. The equipment to perform such studies is already acquired by the laboratory, together with the expertise for data treatment and analysis, for optical data as well as high frequency turbulence and turbidity data. Data analysis will be also performed using multiscale methods developed in the laboratory, in order to consider the coupling in scale and in intensity.
• Candidate profile
This postdoctoral position is intended for a young doctor in oceanography. Some experience in the fields of radiative transfer, turbulence, or particle transport is expected but not required. Experience in field studies, or marine biology, would also be interesting for this position.
