GISP2 * Latitude: 72.970000 * Longitude: -38.800000 * Date/Time: 1990-01-01T00:39:00 * Elevation: 3208.0 m * Recovery: 3053 m * Campaign: GISP * Basis: Sampling/drilling ice * Method/Device: Drilling/drill rig (DRILL) * Comment: GISP2 is a combination of the shallow B and the deeper D core; about 200 ka
The dominant affect on these values is believed to be gravitational fractionation during the gas occlusion process. Last 3 samples are from silty ice; their Kr/Ar and Xe/Ar ratios are affected by geochemical proc other than gravitational frac.
