Description:

Abstract:

This data set contains dielectric profiling (DEP) data from the Greenland Ice Core Project (GRIP) ice core drilled at Summit, Greenland between 1990 and 1992. The data consists of depth (m) and sigma infinity (microsiemens/m). Sigma infinity is the high-frequency limit of the conductivity, corrected to -15 degrees C. The data start at 138 meters below the surface and continue to the bottom of the core. Although a timescale is not given for the data, the data extend to about 110 kyr BP. For more information see: ftp://ftp.ncdc.noaa.gov/pub/data/paleo/icecore/greenland/summit/grip/ecm/ NOTE: PLEASE CITE ORIGINAL REFERENCES WHEN USING THIS DATA!
