These data are particle positions and dates/times which are output from an
OceanParcels particle tracking model simulating likely pathways of floating
marine macro-litter in the Bay of Bengal between 1st June 208 – 30th
September 2019, saved as NetCDF files. The model incorporated advection due to
ocean, wind, and Stokes drift velocities, horizontal diffusion, and particle
beaching behaviours. Two different hydrodynamic data sets were used to force
the particles’ trajectories: a high-resolution ocean velocity hindcast (ROMS –
Regional Oceanic Modelling System) and a lower-resolution dataset which
included data assimilation (CMEMS - Copernicus Marine Environment Monitoring
Service). Sensitivity tests were run to determine whether hourly or daily
forcing resulted in significantly different particle end locations and
validation simulations were run to compare with undrogued drifter tracks for
the same period and region. All model output is stored in NetCDF files. This
is data to accompany a manuscript submitted to Ocean Science entitled
‘Monsoonal influence on floating marine litter pathways in the Bay of Bengal’
(Preprint: EGUsphere - Monsoonal influence on floating marine litter pathways in the Bay of Bengal_). These experiments aimed to determine
source-to-sink connectivity between countries surrounding the Bay of Bengal.
