Other Bering Sea Drifter Deployments: 

This webpage is presented by Steve Ignell of NOAA's Alaska Fisheries Science Center Auke Bay Laboratory and Tom Weingartner of UAF's Institute of Marine Science to show the results of four ARGOS drifters deployed off the mouth of the Yukon River on the Bering Sea shelf in August, 2001. The drifters were drogued at 10m depth and were deployed on August 4, 2001 by the USCG Icebreaker Polar Sea. Black boxes indicate the launch position and black stars indicate the location of the last good position fix. Drifter #11530 had a stuck position sensor for a number of days before successful transmission from Norton Sound.

In the plots below, we show two of the four drifter tracks, with symbols (triangles and circles) plotted every ten days for reference purposes. Note how drifter #11582 (circles, pink in the above plot) went through Bering Strait, returned south of the Diomede Islands and then progressed northward again. Motion along the southwest coast of the Seward Peninsula was very rapid. Drifter #11531 (triangles, blue in the above plot) spent nearly three months in Norton Sound.
