Occurence of macrofossils in the carbonate-rich unit of sediment core CRP-1 (...
Macrofossils are a significant component of biogenic carbonate sediments in the Quaternary section of the CRP-1 drillhole, Cape Roberts, Victoria Land Basin. The middle... -
GISP2 Concentration of H2O2 in surface snow
Samples were collected from the top few millimeters of snow from a 10 x 10 cm area. Samples were generally melted and analyzed within 1 to 3 hours after collection. Analysis... -
GISP2 H2O2 Snow Pit Data
In this file are hydrogen peroxide and oxygen isotope data from 3 snow pits dug beneath automatic depth gauges at Kento and Summit, and adjacent to a thermocouple string at... -

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...
