Summary
Abstract: These data are CO2 concentration of the air occluded in Siple Dome ice core,
Antarctica. The study was conducted between January 2001 and March 2003 on a
deep ice core from Siple Dome Core A, located at 81.66 S, 148.82 W. The data
covers up to the Termination II (around 140,000 years ago). The parameters are
depth in meters and carbon dioxide (CO2) concentration in part per million
(ppm). The ... View entire text

CORING DEVICES Ancillary Description
Quality For each data point, four to six samples from the same depth interval were
dry-extracted mechanically. Each sample has a volume of 4~6 cm3. CO2
concentration was measured with IR tunable diode laser spectroscopy, scanning a
single vibrational-rotational absorption line.
Use Constraints The data before 40,000 yr BP can be used only with permission by the
authors (Jinho Ahn, Martin Wahlen,and Bruce Deck )
