Standing on the Beaufort Sea. In new videos by Frontier Scientists the accounts of Andrew Mahoney, University of Alaska Fairbanks Geophysical Institute assistant research professor, and of Nagruk Harcharek, local whale hunter in Barrow and operations manager for Ukpeagvik Inupiat Corp. Science, come together to describe Arctic sea ice trends. UAF assistant research professor Jeremy Kasper joins Mahoney over the ice to test and deploy buoys for the ice tracker project.

Sea-ice covers the waters of Arctic Alaska for up to 9 months of the year. The patterns of sea-ice movement can be very complex. For example, comments from local residents and the ice radar measurements made from Barrow (Figure 1), Alaska by Hajo Eicken and Andy Mahoney indicate that ice motion can be quite different over small spatial scales. Measurements of ice motion are important for guiding development activities, building better computer models of ice drift, and understanding the ice environment inhabited by marine mammals.
This purpose of this project is to build and test a set of satellite-tracked IceTrackers that can:
Specifically the project will accomplish the following:
The main goal of this program is the design and testing of the IceTrackers. If successful and sufficient demand arises in the future for the IceTrackers, Pacific Gyre believes that the cost per drifter could be as low as $1500. This cost is half the cost of the least expensive ice beacons used in the International Arctic Buoy Program. A secondary, but nevertheless important, outcome of the project will be an improved understanding of ice dynamics in the nearshore waters of Barrow. This information will help in future planning of ice dynamics studies in the nearshore waters of Alaska. A case in point that development of the IceTracker drifters is highly relevant is the fuel barge that is currently adrift in the Chukchi Sea. Responders were able to place a satellite AIS tracker on the vessel but they do not currently have a method of tracking ice around the vessel in the event of oil spilling onto the ice. As a flexible low cost platform, IceTrackers are ideally suited to situations such as the drifting fuel barge.
