Constraint of the CO2 rise by new atmospheric carbon isotopic
measurements during the last deglaciation.
Global Biogeochem. Cycles, 24, GB2015.
doi:10.1029/2009GB003545
The causes of the ~80 ppmv increase of atmospheric carbon dioxide (CO2)
during the last glacial-interglacial climatic transition remain debated.
We analyzed the parallel evolution of CO2 and its stable carbon isotopic
ratio (d13CO2) in the European Project for Ice Coring in Antarctica (EPICA)
Dome C ice core to bring additional constraints. Agreeing well but largely
improving the Taylor Dome ice core record of lower resolution, our d13CO2
record is characterized by a W shape, with two negative d13CO2 excursions
of 0.5‰ during Heinrich 1 and Younger Dryas events, bracketing a positive
d13CO2 peak during the Bølling/Allerød warm period. The comparison with
marine records and the outputs of two C cycle box models suggest that
changes in Southern Ocean ventilation drove most of the CO2 increase,
with additional contributions from marine productivity changes on the
initial CO2 rise and d13CO2 decline and from rapid vegetation buildup
during the CO2 plateau of the Bølling/Allerød.
STUDY NOTES: High resolution record of CO2 and d13CO2 across Termination I
from the European Project for Ice Coring in Antarctica (EPICA)
Dome C (EDC) ice core. This record is compared to existing
lower-resolution EPICA Dome C CO2 data and d13CO2 from the
Taylor Dome Ice core, in order to evaluate mechanisms for
the Termination I CO2 rise.
The experimental procedure of extraction of CO2 and its stable
isotopes, as well as the synchronization of EDC age scale to GICC05,
are described in the methods section of Lourantou et al. 2010.
An even more detailed description can be found in Lourantou, 2009
(PhD thesis, can be found online at:
http://tel.archives-ouvertes.fr/tel-00370658/fr/)
Termination I is the transition from the Last Glacial Maximum
(~20 kyr B.P.) to the Early Holocene (~10 kyr B.P).
