DATA DESCRIPTION:

The profile below shows the temperature of the GRIP borehole as measured
in 1994. The first column is the vertical depths relative to the 1990
surface. This depths deviates from the logging depths used for most other
ice core measurements. The deviation goes from 0 to a maximum of 1.4
meters at the bottom.

The resolution of the original measured data is 0.01K and the absolute
accuracy 0.03K. The temperature in this profile is sligthly smoothed. This
process has removed distubances caused by circulations in the bore hole
liquid below 1500 meters. Non-smoothed, the circulation cells create
disturbances of the order of 0.1K over lengths of typically 20 meters.
