Summary
Abstract: Stable isotopic measurements for atmospheric 13C/12C and 18O/16O at global
sampling sites have been carried out by Dr. C.D. Keeling and co-workers at
Scripps Institution of Oceanography (SIO) since 1977. These isotopic
measurements complement the continuing global atmospheric and oceanic CO2
measurements initiated by Keeling in 1957.

The SIO stations are:
Mauna Loa, Hawaii 1980-2002
Barrow, Alaska 1982-2002
Cape Matatula, Samoa 1984-2002
South Pole, Antarctica 1977-2002
Alert, NWT, Canada 1985-2002
Cape Kumukahi 1980-2002
Christmas Island 1977-2002
Baring Head 1985-2002
Kermadec Island 1984-2002
La Jolla Pier 1978-2002
