GISP2 Oxygen Isotope Data
Measured at University of Washingtons Quaternary Isotope Laboratory. Timescale (down to 2808 m) includes revisions by Meese as of Sept 1994. Depths below 167 m are D core; above... -
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 Meese/Sowers Timescale
Official timescale of GISP2; created by combining the original layer-counted timescale of Meese et al (1994), to about 50,000 years, with a timescale constructed using trace gas... -
GISP2 Layer Counted Timescale
This time-scale provides more annual detail than the official GISP2 timescale (Meese/Sowers timescale, file gisp2age). Core is deformed below 2800m! Annual layers from visual... -
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... -
GISP2 14-C (radiocarbon) measurements (Table 1)
Approx age of ice based on layer counting and delta 18O data for trapped air (Grootes et al., 1993; Sowers et al., 1993; Meese et al., 1994a; Stuiver et al., 1995). Typical... -
GISP2 Beryllium10 concentration, 719-2253 m
Melted water was collected from the outside of samples taken for cation and anion analysis by UNH. An aliquot was taken for anion analysis (chloride, nitrate, sulfate) and the... -
GISP2 B Core Depth Age Scale
Final layer-counted timescale for GISP2 B-core. Based on dating committee`s recom., the B-core is offset from the D-core by 1.09 meters, and a correction has been made in all... -
ATM aerosol concentrations around the GISP ice core site
Aerosol filter sampling was conducted during the summers of 1993 and 1994 at the solar powered remote atmospheric sampling site located 28 km southwest of the GISP2 camp... -
GISP2 accumulation rate history
Accumulation rate values were calculated de-straining the depth-age scale of Meese, Sowers, et al. 3 Versions correspond to 3 different ice dynamics situations, as described in... -
GISP2 Volcanic markers
Volcanic sulfate record on Meese/Sowers timescale. Each sample is approximately bi-annual for the last ~12,000 years with a consistent increase in the time covered by each... -
GISP2 Ions: Deep (D) Core
Ion data set produced by the Glacier Research Group for the GISP2 D core, from 2 - 3040 m. 2 to 96 m is B core data. The remainder of data is from D core. D core samples were... -
GISP2 Ions: B core (0-200 meters)
This is the ion data set produced by the Glacier Research Group for the GISP2 B core drilled at the GISP2 site during the summer of 1989. The data is bi-yearly, a combination of...
