This visualization shows OSCAR (Ocean Surface Current Analysis Real-time) ocean currents colored by current velocities. OSCAR data (produced by Earth & Space Research and distributed through NOAA and PO.DAAC) is derived from observed satellite altimetry and wind vector data. The visualization runs from January 1, 2008 through July 27, 2012. Blues are slow currents, greens currents are about 0.5 meters per second, and red currents are about 1 meter per second. This visualization was rendered in a variety of sizes from standard 1080p HD to 4k to 6840x3420. The higher resolution versions were rendered for very high resolution display technologies such as hyperwalls and cinema projectors.

These visualizations were developed, in part, for display at the "20 Years of Progress in Radar Altimetry" Symposium in Venice, Italy in September 2012 and for the Fall 2012 American Geophysical Union conference in December 2012.
A cropped region in the Pacific illustrating the distribution of the actual flow vector data points relative to the flow curves. The white dots represent locations where the OSCAR model defines the ocean current directions. Locations in between are interpolated.
