Record #125062:

What was the carbon dioxide content of the glacial atmosphere? / A.T. Wilson, A. Long.

Title: What was the carbon dioxide content of the glacial atmosphere? / A.T. Wilson, A. Long.
Author(s): Wilson, A. T.
Long, A.
Date: 1993.
In: Eos : transactions, American Geophysical Union. (1993.), Vol. 74(43, supplement) (1993)
Abstract: Abstract. All published polar ice-derived data on CO₂ content of past atmospheres were obtained by ice crushing or grinding yielding recovery of about 75% of CO₂ in ice. Here, sublimation was used on samples of Greenland Ice Sheet Project 2 (GISP2) core to extract 100% of trapped gases. Shows that processes of gas entrapment and release of CO₂ into bubbles are more complex than hitherto believed.
