This image shows the variation of the Gulf Stream velocities near the East coast of North America in the last 20 days. The images are updated daily and the velocities are in metres per second (to get the approximate velocity in knots, multiply by 1.9438445).

Since 22 July 2003 the Gulf Stream velocity fields derive from near-real-time radar altimeter data of the European Environmental Satellite Envisat. At the same time the mapped area was increased to show more upstream regions of the Gulf Stream.
