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... -
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 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... -
