Observation et modélisation des macro-déchets en mer Méditerranée, de la large échelle aux échelles côtière et littorale

Abstract : The main objective of this work is to study the floating marine debris transport mechanisms and their potentialaccumulation in the Mediterranean Sea, using numerical modelling and in-situ observations of debris. Thetransport dynamics is analysed in terms of typical scales in the basin, from the large scale to the coastal andlocal scales.First, the analysis of a Lagrangian experience data set show the potential existence of non-permanent and largeretention areas (Mansui et al., 2015a). In a second stage, the coastal impact of a boundary current (the NorthernCurrent) and atmospheric forcings on the local distribution and stranding of floating marine litter has beenestimated (Mansui et al., 2015b, under revision), using an original set of data combining offshore sightings andbeaching surveys.
