General Information

In 1974, CRREL recovered a 12.7 cm diameter, 404 m long ice core at Crete as part of the international Greenland Ice Sheet Program (GISP). CRREL was the lead US laboratory (Hansen and Langway, co-PIs) for GISP. The Crete ice core was drilled by Lyle Hansen, John Rand, and Robert Bigl using CRREL’s thermal drill. The core is on the de-accession list.
