Our current understanding of the global carbon
cycle has greatly benefited from atmospheric O2 measurements,
pioneered by R.F. Keeling and collaborators in 1990. Our parallel sampling program, with sampling
locations added periodically beginning in 1991, now includes Point Barrow
(Alaska), Sable Island (Eastern Canada), American Samoa (Tropical South
Pacific), Amsterdam Island (Indian Ocean, French station), Cape Grim (Tasmania,
Australia), Macquarie Island (subantarctic Australian station), and Syowa
(Antarctic Japanese station). Samples
are also routinely collected on Ka’imimoana, a U. S. NOAA ship operating in the
equatorial Pacific.
