Record #125151:

The GRIP records of atmospheric CH₄ and CO₂ and their link with Greenland climate / J. Chappellaz, and 6 others.

Title: The GRIP records of atmospheric CH₄ and CO₂ and their link with Greenland climate / J. Chappellaz, and 6 others.
Author(s): Chappellaz, J.
Date: 1993.
In: Eos : transactions, American Geophysical Union. (1993.), Vol. 74(43, supplement) (1993)
Abstract: Abstract. Presents new methane measurements in Greenland Ice-core Project ice core revealing that: (i) variations in concentration of up to 10% occurred between 900 and 1800 AD; (ii) compared with Antarctic results, interhemispheric CH₄ difference of 50 ppbv can be drawn during pre-industrial times; (iii) during last deglaciation, atmospheric CH₄ closely parallels Greenland climate with no significant lead or lag on major climatic events (e.g. Younger Dryas); and (iv) isotopic events characterizing Greenland climatic record between 40 and 20 ka BP are associated with similar changes of atmospheric CH₄ concentration. Concerning CO₂, GRIP results confirm industrial increase and glacial--interglacial variations observed on Antarctic records, but also show higher scattering and higher concentrations than in Antarctic ice.
