This visualization shows a view of looking down on a virtual (computer model) ocean from space as if you could:
* see the upper one meter of ocean surface current speed;
* speed up time by x86400, so that one second of elapsed time is equal to one day;
* see down to about one kilometer horizontal resolution.
The period of the visualization covers September 2011 through January 2012. The numerical formulation includes ocean circulation and tidal forcing and uses atmospheric state from reanalysis at a global resolution of about 1/4 degree.
