Site A

General Information

As part of the site-selection activities for the Greenland Ice Sheet Program 2 (GISP2) deep drilling, two 100 mm diameter cores at Site A were drilled in 1985 using the electromechanical PICO 4-Inch Drill. Only one of the cores remains (core 2; core ID: SITE A2) in the ICF archive. The core is 100 m long, pore close-off occurs at about 75-80 m depth, and the accumulation rate is about 290 mm a-1 ice. The core is not continuous and is on the de-accession list.
