 n \nAbstract:\nOcean currents transport material like nutrients\, plankto
 n and plastic over the globe. The most natural way to study these transpor
 t pathways is by simulating virtual Lagrangian particles in fine-resolutio
 n ocean models.\nIn this seminar\, I will give an overview of some recent 
 work with Lagrangian particle analysis. I will introduce our open-source p
 arcels-code.org framework and its new developments to support output from 
 the ICON and FESOM models. I will show how we use this framework to simula
 te the transport of micro- and macroplastic\, in order to map their distri
 butions on scales of kilometres. I will discuss how we develop new paramet
 erizations for subgrid-scale transport processes of floating material\; an
 d compare these parameterizations to field and lab measurements. I will pa
 rticularly focus on coastal processes and how they control the beaching\, 
 resuspension and fragmentation of particulate items. \n \n \n\nhttps://
