Title: Sedimentation of microplastics in the ocean mixed layer: numerical study of a model system

Laboratory: Unité de Mécanique de Lille J. Boussinesq, Univ. Lille Villeneuve d’Ascq, Cité Scientifique

Supervisors:  Enrico Calzavarini et Stefano Berti (Univ. Lille, ULR 7512 – Unité de Mécanique de Lille – Joseph Boussinesq (UML))

Duration: 6 months (from february/march 2023)

In collaboration with Dr. Tristan Biard and Laget Manon (LOG UMR 8187) we propose an analysis of field measurements of deep sea particle sinking fluxes.
Duration: 6 months
Internship main location : Laboratoire d’Océanologie et Géosciences (UMR 8187) – Wimereux – France
Internship description and application rules:  M2_internship_proposal

Visualization of the velocity field in a moderately turbulent Kolmogorov flow (spatial resolution 128^3). The  flow is sustained by a steady unidirectional force (here along the X axis)  with a monochromatic sinusoidal dependence proportional to  sin(k Y).  The sinusoidal profile is clearly reflected in the large scale velocity field in the X-Y planes (visible at the beginning and at the end of the movie).
