Figure 1. Estimated 4-day ice motion vectors estimated between January 13 and January 17, 1994 with SSM/I 85.5 Ghz image for January 13 as background. The ice motion vectors in white are from the maximum cross-correlation technique. The small square marks the beginning of the displacement vector. Black vectors are ice motion estimated from Arctic drifting buoys. The large circular region centred over the North Pole is a data void region of the sensor. The ice motion shows the very strong anti-cyclonic Beaufort Sea Gyre in the Canada Basin and large ice motion in Fram Strait (between Svalbard and Greenland).
