GISP2 14-C (radiocarbon) measurements (Table 2)
Expected in-situ 14C is based on 14C production rate at surface for the present altitude (3.2 km), 200 atoms 14C/g ice/y (Jull et al., 1994), and model ice accumulation rates... -

GISP2 Laser Light Scattering in high resolution from meltwater
Measured from meltwater to obtain particle concentration along the shallow portions of the core (<1650 m) before it was replaced by LLS from solid core. -

GISP2 Methane Concentrations
Ice ages were calculated by linear interpolation from the Meese et al. timescale. Depth is midpoint of sample. -
GISP2 Isotope Concentrations in Trapped Air
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... -
GISP2-D Borehole Diameter
Depth=TVD true vertical depth. The diameter of the 3-km borehole (GISP-D) at the GISP2 site was measured during 1993, 1994, and 1995 using University of Copenhagens geophysical... -
GISP2 Ar, Kr, and Xe data
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... -
GISP2 CO2 concentrations
Average CO2 concentrations of air extracted from depths spanning two separate stadials (cold periods) centered at approximately 46 kyBP and 63 kyBP. Measurements made on 6-8...
