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 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 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) 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 ice core detailed water isotope (δ18O) data
The ice core was drilled during the GRIP project in 1989-1992 at the Summit of the Greenland ice sheet. The length is 3025 m. Present-day accumulation 0.23 m ice/yr. Position... -
