Current
Research: Confronting the
global carbon budget: New stable Carbon isotope ratio data
of CO2 from EPICA / Dome C ice core over the last deglaciation:
experimentation and interpretation
This project belongs to the general framework of International
Geosphere-Biosphere Program (IGBP) which aims towards
a better understanding of potential interactions between
climate - biogeochemical cycles. The main study interest
lies in distinguishing different sources and sinks
of major greenhouse gases, in order to better constrain
the global carbon budget. This will be achieved by
combining experimental work with modelling work, technical
know-how with pure scientific research.
During the first year of this PhD thesis, carbon dioxide,
CO2 (the major anthropogenic greenhouse gas), as well as
its stable isotope ratios, δ13C and
δ18C of CO2 were
of particular interest and their in parallel evolution during
the last
deglaciation (20 to 11 kyrs BP) was registered, having as
sampling area the recently drilled ice core of EPICA Dome
Concordia in Antarctica. In order to achieve this, an extraction
/ preconcentration line (already developed in LGGE) is used,
connected to a Gas Chromatograph (GC) and an Isotope Ratio
Mass Spectrometer (IRMS). Once the first EPICA Dome C results
obtained, some first data interpretation as well as modelling
work, by collaborating with LSCE in Saclay, Paris took place.
The aim of this modelling work is to better constrain already
developped models (box models and models of intermediate
complexity) using the obtained data, thus having some information
about the mechanisms dominating the last deglaciation period.
In the beginning of 2007, further analytical work on CO2 and
its stable isotope ratios measurements for another Termination* is planned to be accomplished. A change of protocol will
happen just afterwards, as the whole analytical system will
be switched to methane (CH4)
requirements (measuring CH4 mixing
ratio as well as its stable isotopic ratios, δ13C and
δD
of CH4).
The second semester of the second PhD year will be dedicated
to results interpretation, as well as modelling
work with the collaboration of the University of Bristol.
The third year will be normally dedicated to amelioration
of the above techniques, scientific papers editing and PhD
thesis editing.
This
project (ESR XII) contributes partly to science
objective 1 (Quantify feedbacks in the global carbon
cycle) and partly to science
objective 3 (Improve understanding of natural
sources of CH4 and
their responses to human activities) of GREENCYCLES and has
links to the projects of Valentina (ESRVI),
Marcin (ESR
X) and Roxana (ESR XI)
