Trends, seasonal cycles, and interannual variability in the isotopic composition of nitrous oxide between 1940 and 2005 EOS Trans. AGU, 89(53), Fall Meet. Suppl., Abstract A21A-0125, 2008 (Ref: 13894)
Authors:
Park S.Croteau P.Boering K.A.Etheridge D.Ferretti D.Fraser P.Kim K.Krummel P.Langenfelds R.Trudinger C.van Ommen T.
Category 3: Abstract

We present measurements and analysis of the isotopic composition (ä15Nbulk, ä15Ná, ä15Nâ, and ä18O) of nitrous oxide in 50 samples of tropospheric air collected at Cape Grim, Tasmania between 1978 and 2005 and in 11 samples of firn air from Law Dome, Antarctica…

Carbon dioxide and methane changes over recent millennia from the ice core record: causes, climate forcing and feedbacks Carbon Workshop 2008: Global Cycle to Regional Budget, Wellington, NZ, April 14-15, 2008 (Ref: 13309)

Category 3: Conference paper

Measurements of atmospheric trace gas composition from times before reliable direct observations began in the late 20th century come from air enclosed in polar ice and firn. This presentation will review the evidence for changes in atmospheric CO2…

Category 1: Peer-reviewed literature

We report a 2000-year Antarctic ice-core record of stable carbon isotope measurements in atmospheric methane (ä13CH4). Large ä13CH4 variations indicate that the methane budget varied unexpectedly during the late preindustrial Holocene (circa 0 to 1700 A.D.). During the first thousand years…
