Animations of tracked Puddies (1 year, 5 day time intervals), for the four analysis regions (zoom-ins).

Background:
* Colors: oxygen [umol/kg].
* Thick white contour: 200 umol/kg climatological oxygen contour. 
* Contours: isopycnal layer thickness, 20 m intervals.

Tracks:
* Thin red/gray lines:  eddies existing 3 months or more.
* Thick red/gray lines: eddies existing 9 months or more.
* Red lines: eddies originating in climatological oxygen conditions less than 200 umol/kg and a net westward propagation, gray lines: all other eddies.
* White circles: eddy centers.
* White circles marked by cross: last time step of eddy track.
