Indonesia is particularly impacted because of its high population density, heavy rainfall rate and numerous coastlines. A Lagrangian analysis was performed to simulate the fate of fictive marine debris drifting along surface currents, including tides and Stokes drift. The fictive particles were released according to the discharge rate of 21 Indonesian rivers and advected over 4 years. Most of the particles were stranded along Indonesian coasts (60%), before 6 months had elapsed (84%) and within a range of 1000 km (76%). The time variability exhibited two seasonal peaks, one centered on January-February and one on June-July, consistent with in situ observations. However, the results underline the complexity of performing direct comparisons between in situ observations and numerical simulations for stranded waste due to limited measurements and the heterogeneity of field methods and protocols. specialized marine debris plastics dispersion numerical modeling strandings Indonesian seas INDONESIE 038 062 032 020 10 8 1009 [18 p.] 2022 https://www.documentation.ird.fr/hor/fdi:010085931 10.3390/jmse10081009 [F B010085931] https://www.documentation.ird.fr/hor/fdi:010085931 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2022-09/010085931.pdf IRD - Base Horizon / Pleins textes 2022-09-28 2025-02-24 fdi:010085931 fre
