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 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...

GISP2 Ions: Shallow (B) Core (Detailed)

GISP2 major ion concentrations in parts per billion (ppb) by mass. Blanks in the H2O2 data indicate samples that were not analyzed. Blanks in other chemical species represent...

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 Ions: Deep (D) Core (Detailed)

GISP2 major ion concentrations in parts per billion (ppb) by mass. Blanks in chemical species represent samples below detection limits. Firn samples were cleaned in the freezer...

GISP2 Oxygen Isotope Data (1 year averages)

The timescale includes revisions by D. A. Meese as of Sept 1994. Depths below 167 meters are those of the D core; above 167 meters the depths are those of the B core + 1.09...

GISP2 Bidecadal Oxygen Isotope Data

The timescale includes revisions by D. A. Meese as of September 1994. The GISP2 depths below 167 meters are those of the D core; above 167 meters the core depths are those of...

GISP2-D Temperature

Depth is true vertical depth. Sample spacing for the primary temp logs is 20 cm, accuracy is 4.5mK. The "uncorrected" data were obtained on 14June1995. Quality is insuff for...
