GISP2 Laser Light Scattering
Compilation of detailed solid ice laser light scattering (LLS) files; ssentially 1 meter averages (every 500 data points averaged) above 2100 meters and 1/2 meter averages below... -
GISP2-D Borehole Geometry
Inclination and azimuth was meas. 1993, 1994, 1995 using Univy of Copenhagens geophysical logging system (UCPH), described by Gundestrup et al., (1994). Continued measurements... -
GISP2 14-C (radiocarbon) measurements (Table 3)
Calculated accumulation rates from 14C data (Table 3 in Lal and Jull (1997) compared with glaciological flow-model estimates (Cutler et al., 1995). -
Oxygen isotope data from snowpit at GISP2 Site 571
Data from shallow cores recov. over a 150x150 km grid in central Greenland. Dating of samples based on seasonal variation in oxygen isotope stratigraphy, along with measurements... -
Oxygen isotope data from snowpit at GISP2 Site 44
Data from shallow cores recov. over a 150x150 km grid in central Greenland. Dating of samples based on seasonal variation in oxygen isotope stratigraphy, along with measurements... -
GISP2 Electrical conductivity measurements (average data)
This ECM data represents 0.5 meter averages of the full resolution data. The GISP2 B core was used for the first 100 meters; the D core thereafter. All depths are D core depths,... -
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. -
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 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...
