Atmospheric CO2 and Climate: Taylor Dome Ice Core, Antarctica, Version 1

Using new and existing ice core CO2 data from 65 - 30 ka BP a new chronology for Taylor Dome ice core CO2 is established and synchronized with Greenland ice core records to study how high latitude climate change and the carbon cycle were linked during the last glacial period. The new data and chronology should provide a better target for models attempting to explain CO2 variability and abrupt climate change.

Data Acquisition and Processing

Data Acquisition Methods

The CO2 mixing ratio was measured with an Agilent 6890N Gas Chromatograph (GC) with flame ionization detector, with nickel catalyst conversion of CO2 to CH4 prior to measurement.
