Greenland Ice Core Project (GRIP) Oxygen Isotope Data, NOAA/NGDC, WDC-A Paleoclimatology

Summary
Abstract: This data set consists of detailed oxygen isotope (del 18O)
measurements from the 3029 m Summit Core in Greenland collected by the
Greenland Ice Core Project (GRIP) members. The isotope measurements
were made on 0.55 m sections of ice, and reported relative to the
interval and the midpoint of the section. The data presented here and
published in the references were produced by appending a series of
files containing data from different files (representing different
field seasons), and applying the age model described in Dansgaard, et
al, 1993. The data record spans 0 to 250,000 yBP.
