 **Parcels** provides a set of Python classes and methods to create customisable particle tracking simulations using gridded output from (ocean) circulation models. Parcels can be used to track passive and active particulates such as water, plankton, [plastic](http://www.topios.org/) and [fish](https://github.com/Jacketless/IKAMOANA).
