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 Visual Stratigraphy
Visible-stratigraphic log of the upper part of the GISP2 ice core, based on observations by R.B. Alley in the Holocene and Alley and C.A. Shuman in the late glacial, as compiled... -
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 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 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 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-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 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... -
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 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 Methane Concentrations
Ice ages were calculated by linear interpolation from the Meese et al. timescale. Depth is midpoint of sample. -
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 D-core methane sulfonic acid concentrations
This dataset has no description
-
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... -
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... -
ATM Concentration of H2O2 in atmosphere

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.
