Summary

Abstract: This data set consists of atmospheric methane (CH4) concentrations
from the 3,230 m ice core taken by the Greenland Ice-core Project
(GRIP) covering the period between 40,000 and 8,000 yBP. Methane
concentrations were measured from the air trapped in the ice.

The file contains five columns:

Column 1: True depth (meters below the surface)
Column 2: Mean age of the trapped air (calendar years ...
