Fixes were received from Service Argos and obviously erroneous positions were deleted. Velocities more than doubled over the narrow portion of the shelf south of St. George Island. After reaching the Pribilof Islands, the buoys were entrained into the flow around the islands. One drifter circled St. Paul and then continued northward. The second drifter circled both islands and then re-entered the Bering Slope Current.
Tidal loops are clearly evident in the trajectories.
In 1993, a satellite-tracked buoy was deployed on the Bering Sea shelf south of the Pribilof Islands. It was transported northwestward to the vicinity of St. George Island where it circled the island seven times in 60 days before it lost its drogue. One period of consistent clockwise circulation is shown in Figure 3 . Mean circular velocity was about 20 cm s -1 and mean speeds did not appear to be markedly different on the different sides of the island. Diurnal tidal ellipses are evident although very small.
