GRIP Basal Ice: Crystal Sizes
Depth is midpoint. Crystal refers to the average horizontal crystal diameter in mm. -
GRIP Ice Fabric
36 fabric diagrams. Each data point consists of azimuth of c-axis (0-360 deg), and inclination (0-90 deg), with 0 deg=horizontal c-axis and 90 deg=vertical c-axis. The measured... -
GRIP c-axis orientations
Average horizontal and vertical crystal diameters, obtained by linear-intercept measurements on thin sections. Data not corrected for sectioning effect. Depth is midpoint. -
GRIP Dielectric Profiling (DEP) in full resolution
Sigma infinity has a pure ice background of 9 microsiemens/m, and responds to the chemistry of the ice. The only components known to cause an increased sigma infinity are... -
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 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 Basal Ice: Debris Content
Depth is midpoint -
Stable isotope records of Arctic and Antarctic ice cores
Polar precipitation archived in ice caps contains information on past temperature conditions. Such information can be retrieved by measuring the water isotopic signals of ?18O... -
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... -
(Table 1) Micro-inclusion counts and ion concentrations in the five GRIP ice-...
We provide the first direct evidence that a number of water-soluble compounds, in particular calcium sulfate (CaSO4 2H2O) and calcium carbonate (CaCO3), are present as solid,... -
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... -

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... -
GISP2 Stratigraphy
Depths of mid-summer as determined separately from ECM and visual stratigraphy in the GISP2-D ice core. Also given are calculated layer thicknesses (true and ice equivalent) and... -
