Stable Isotope Data from Basal Ice, GRIP Core
Data are continuous averages for the average (midpoint) depths given. -
GRIP Carbon Dioxide measured by infrared laser absorption spectrometer, IRLS
Measurements were performed on 0.55 m long sections. For each section, several samples of size 2.5 cm (5 g) along these sections were measured and averaged. -

GRIP Dielectric Profiling (DEP) and Electrical Conductivity (ECM) averaged data
Each data point is an average over a 55 cm interval; data are correted, level changes between 730 and 930 m are believed to be spurious (Wolff, et al., 1995) due to poor... -
GRIP Methane Data (LGGE)
Age is mean age of trapped air in kilocalendar years before 1950. Sample depth relative to surface of summer 1989. One sample =4cm core. -
GRIP Methane Data (Bern)
Depth below the surface of summer 1989. One sample = 2 cm. Age is Gas age. Data measured in Bern. -
GRIP total air content
Depth is midpoint relative to summer 1989 surface. Age is given as gas age in kilocalendar years before 1950. -
GRIP Accumulation Rates
Depth at the top of the sample -
GRIP Acidity
Data calculated from electrical conductivity; depth is given at the local maximum in the ECM record; age is given at the local acid peak -
GRIP Carbon Dioxide measured by gas chromatography
Measurements of CO2 concentration have been made on samples of about 40 g or 3 cm height. Some depth were measured several times. -

Crystal size variations in Eemian-age ice from the GRIP ice core, Central Gre...
Continuous measurements of ice crystal size have been carried out on an 80 m sequence between 2790 and 2870 m depth in the GRIP ice core from Central Greenland. The ice in this... -
Ion concentration and deduced chemical compounds of the GRIP and Dome Fuji ic...
We have proposed a method of deducing the chemical compounds found in deep polar ice cores by analyzing the balance between six major ions (Cl-, NO3-, SO4**2-, Na+, Mg2+, and... -
Synchronization of the NGRIP, GRIP, and GISP2 ice cores
We here present a synchronization of the NGRIP, GRIP, and GISP2 ice cores based mainly on volcanic events over the period 14.9-32.45 ka b2k (before AD 2000), corresponding to... -
Mineralogy and isotope chemistry of GISP2 and potential source areas
Samples of dust from the Greenland Ice Sheet Project 2 (GISP2) ice core, Summit, Greenland, dated within marine isotope stage 2 (between 23,340 and 26,180 calendar years B.P.)...
