     "_Example of load-balancing for Particles. The domain is chunked along the thick lines, and the orange and blue particles are on separate MPI processors. Before load-balancing (left panel), two chuncks in the centre of the domain have both orange and blue particles. After the load-balancing (right panel), the Particles are redistributed over the processors so that the number of chunks and particles per processor is optimised._\n",

     "The difficulty is that since we don't know how the `ParticleSet` will disperse over time, we need to do this load-balancing 'on the fly'. If you to contribute to the optimisation of the load-balancing, please leave a message on [github](https://github.com/OceanParcels/parcels/issues)!\n"
