SUMMARY REPORT:
DEEP CARBON CYCLE WORKSHOP
MAY 15-17, 2008 – Carnegie Institution, Geophysical laboratory
Session I: The first breakout session on deep carbon reservoirs was chaired by Steve Haggerty (Florida International University). The surprising
conclusion regarding key unanswered questions is that little is known about the nature and extent of deep carbon reservoirs. Uncertainties remain
about the major carbon-bearing phases, the extent to which carbon may be incorporated as a trace element in nominally “a carbonaceous” minerals,
the nature of C-O-H-N fluids in the mantle, the presence of organic molecules in deep reservoirs, and the nature and extent of deep microbial life. A
realistic objective for the next decade, therefore, is an understanding of the nature of all possible deep carbon reservoirs as a function of
temperature, pressure and compositions of both rocks and volatiles. It was emphasized that equally fundamental is an understanding of fluxes and mass
balance among reservoirs (see session II). Longer-term goals include a fundamental understanding of modes of CO2 sequestration, determination of
possible fluxes of a biotic organic species, and the search for high-pressure forms of “life” that are as yet unknown.
A massive amount of material to study in the coming weeks :

Start with this MP4 presentation :
Keynote speech, by Ronald Cohen, Geophysical Laboratory :
"Carbon from Earth's surface to its core"
All the other Power Point and MP4 lectures and presentations are very interesting for anybody with a scientific background, and will be of great help
for everyone genuinely interested in this subject.
