Introduction 
The program in the Arctic of the United States of America during 
the International Geophysical Year (1957-1958) included a drifting pack 
ice station in the Arctic Oceans This pack ice station, Drifting Station 
Alpha, was a joint effort of the United States Air Force and the United 
States National Committee for the IGY. The geophysical studies of ice, 
o¢ean and ocean floor were carried out by Lamont Geological Observatory 
under contract from the Geophysical Research Directorate of Air Force 
Cambridge Research Center. These geophysical studies are the subject of 
this report. The original contract provided for work at Station Alpha 
but it was extended to cover further work on Drifting Station Charlie (1959) 
and on Drifting Station Bravo (T-3, 1960). This report is a summary of the 
work done only. Detailed results of the findings of this project are found 
in the papers and scientific reports published under the contract and 
listed in the bibliography.
