Ocean pathway estimation using Drifter.jl and Oscar flow fields

Daily flow fields for year 2021 are read consecutively and virtual sea water parcels (100,000) are tracked as they follow this time variable flow field.

Estimated Trajectory Files :

• The larger file contains model output for 360 days and 100,000 parcels.
• The small file contains a subset of 30 days and 50,000 parcels.
• An animation is included and can be viewed at https://youtu.be/RZINMlXc_fA
