GRIP Temperature Profile
T measured 1994. Depths deviates from logging depths used for most other ice core measurem. from 0 to max of 1.4 m. Resolution=0.01K; abs. accuracy=0.03K. Data sligthly smoothed... -
GRIP Electrical Conductivity
Depth refers to the top of the sample. Data are averaged in 55 cm intervals. unit=microeq/kg obtained by H+=0.085i[microA]1.63 above 297m and H+=0.045i[microA]**1.73 below 297m. -

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 -
Electrical conductivity measurements (ECM) from the DYE-3 ice cores (main cor...
ECM data of the DYE-3 cores obtained with the technique described by Hammer (1980). People involved in the measurements include Henrik B. Clausen, Dorthe Dahl-Jensen, Niels... -

Continuous melting technique, combined with continuous flow analysis (Sigg et al., 1994). A subcore with a cross section area of 18x18mm2 cut is used. -
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. -
