Minimum DEPTH, ice/snow: 116.3000 m * Maximum DEPTH, ice/snow: 3038.0000 m
Event(s):
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
Comment:
Ice ages were calculated by linear interpolation from the Meese et al. timescale. Depth is midpoint of sample.
