After the completion of Dye 3, ice coring in Greenland stalled. Peter Wilkness, who was in command of Polar Research at the National Science Foundation, was angry that although the U.S. had paid most of the bills for the two Greenland ice cores, European scientists had reaped the giant’s share of the scientific glory. Because of this, he refused to fund further coring efforts. Lacking airplanes capable of transporting the heavy loads of equipment into Greenland’s interior, the Europeans found it difficult to continue on their own. So there were no plans for further coring.
