The movie shows three screen views:
1) The evolution of the geometry of the neutral density surface gamma_n = 27.9 over a year.
The colours indicate the depth in meters.
This neutral density has been chosen for the release of tracer in the DIMES experiment.
One can identify the annual cycle from the retreat of the isopycnal surface in the Weddell Sea
as the sea-ice progressively extends further north in austral winter.
2) The release scheme for the particles
(which is similar to that used for the release of the chemical tracer in DIMES).
3) Lagrangian trajectories of particles.
The length of the trajectories corresponds to the distance travelled
during the last 100 days.
Colour changes denote years of travel.
