HOTRAX05- The 2005 Healy-Oden Trans-Arctic Expedition was the second U.S. surface ship to cross the Arctic Ocean. The U.S. Coast Guard Icebreaker Healy left Dutch Harbor, Alaska, on August 5, 2005, conducted various geophysical experiments and reach the North Pole on September 12. After the Pole, it took more than a week to get through 200 miles of heavy ice pack, reaching Tromso, Norway on September 30, 2005.

Paul Henkart is a Geophysical Analyst (computer programmer) at Scripps Institution of Oceanography in La Jolla, CA. He spent 12 years in oil exploration with Texaco in Houston and Calgary before joining Scripps in 1978. He's not a desk-bound programmer but has spent a couple of years on ships collecting seismic data.
