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:
Data in delta notation, standard is present day atmosphere. Ages are ice ages, calculated by linear interpolation of the Meese et al. (1997) timescale. Not gas ages: no calculation of the ice age-gas age offset in this data set.
