 The flow field consists of [rigid body rotation](https://en.wikipedia.org/wiki/Rigid_body), plus a convergent term, plus a sinking term in the vertical direction. This flow field generates a downward, converging spiral -- a idealized version of a relevant case in the Ocean.

 A simulation of floating particles over the Global Ocean which illustrates (1) using time variable velocity fields, (2) global connections, (3) particle re-seeding, and (4) output statistics. 
 
 The flow field is based on a data-constrained ocean model solution. The problem is configured in a way to mimic, albeit very crudely, the near-surface tranport of plastics or planktons.

 A simulation of particles that follow the three-dimensional ocean circulation. This example illustrates (1) the 3D case in a relatistic configuration, (2) tracking the advent or origin of a water patch, and (3) multifacted visualizations in 3D.
 
 The flow field is based on a data-constrained, realistic, ocean model. The problem configuration mimics, albeit very approximately, ocean tracers / coumpounds transported by water masses .
