SEA SURFACE CURRENTS > Dynamically rendered hourly currents

The animation below uses streaklines to show the speed and direction of sea surface currents. Streaklines are made by drawing a set of points and then moving them around according to the speed and direction of the currents at their location. Note that streaklines are not time-sequence animations, nor do they represent the trajectory of floats. They are simply a different way to visualize the motion of the sea surface currents. The currents shown are an average of the measurements taken during the previous hour. The animation may be paused and restarted by clicking anywhere on the map.

Note: Time is in UTC (PST -8/PDT -7). The area shown is from Point Reyes north to Bodega Bay, CA.
