Tracking how ocean currents transport plastic, plankton and other materials

The Lagrangian Ocean Analysis team at Utrecht University

The Lagrangian Ocean Analysis team within the Institute for Marine and Atmospheric research at Utrecht University's Department of Physics, uses the Parcels framework to create and analyse simulations of the transport of material (plastics, plankton, fish) by ocean currents and its impact on climate and marine ecosystems. Within the group, we adhere to Open Science principles and aim to create a collaborative and inclusive atmosphere.
