资源简介：
This data set includes carbon-14 measurements on atmospheric methane obtained
from air bubbles in glacial ice at the Pakitsoq outcrop in western Greenland,
during two abrupt increases in methane concentration during the last
deglaciation (14.7 and 11.6 kyr BP). Supporting measurements of oxygen-18 of
O2, nitrogen-15 of N2, methane concentration, and oxygen-18 of ice used to
establish the chronology are also included. The data were collected between
2001 and 2005 in a test of the "clathrate hypothesis", that massive releases of
methane from marine methane hydrates caused the observed abrupt increases in
atmospheric concentration at those two times.
