Numerical lagrangian data issued from river sources in Indonesia

The data allows to describe the Lagrangian trajectories of fictive particles in ocean model from major river discharges in Indenosia. The project aims at strengthening Indonesian institutions awareness and knowledge about marine pollution by plastics, in order to implement appropriate interventions. prevention and recommendation, through support to the monitoring and modelling of marine debris. Our intention is to propose a statistical view of possible sites for accumulation of plastics for different seasons and different nino/nina years. The statistical will be obtained by changing different parameters of numerical models and Lagrangian schemes and running realistic long simulation. Validate the models and hypothesis against in-situ data, including dedicated launch of drifters and microplastics cruise on a test case region, north of Java Island. The project will also include a series of in situ validation, both for Lagrangian trajectory in a specific site off the Java Coast and collect in-situ data for validation of the ocean model.
