vited contributions of 2013 geoscience laureates of the French
ademy of Sciences
Each year, the French Academy of Sciences gives out a
ber of prizes and medals to recognize the contribu-
s and achievements of outstanding colleagues in all
ds of Science. In 2013, for the first time, laureates have
n invited to make short presentations at the Academy.
s resulted in a special session that generated enthu-
m from participants, including many members of the
demy. The editorial team of Comptes rendus Geoscience
 felt that it could be of interest to the scientific
munity to have access to presentations by these
ntists in the geoscience series of the Comptes
dus. Six laureates of the 2013 Academy Awards
ponded positively to the invitation. Because these were
ited papers, an Associate Editor and the Chief Editor
yed the role normally attributed to reviewers, in
ition to their normal editorial duties. In some cases,
ernal reviewers were also involved upon invitation by
 Editors. We are thankful to the authors and happy to
sent readers of Comptes rendus Geoscience with this first
ies that, if successful, could be followed by others in the
ing years.
The first paper, by Vincent Deparis (laureate of the
3 Paul Doistau–Émile Blutet Prize for Scientific
rmation), summarizes the main phases through which
 present-day views of the Earth’s interior came to be
ped over the past centuries. He retraces this evolution
r seven main periods and 2000 years, from the pre-
0 to the post-1950 understanding of our planet.
aris illustrates how some important ideas first appear,
n sometimes disappear only to reappear again with
rovements. He shows how the opposed views of
cartes (spherical, stratified, static Earth; few links
ween surface and depth) and Kirsher (heterogeneous,
amic Earth; significant links between surface and
th) have in a way come to be reconciled in the second
f of the twentieth century.
In the second paper, Paul Tréguer (laureate of the
3 Georges Millot Medal) gives what could be the first
quantitative overview of the cycle of silica in the Southern
Ocean. He evaluates the balance between input fluxes from
the upwelling of the Circumpolar Deep Water and
exported fluxes through the SubAntarctic Mode Water
and the Antarctic Intermediate and Bottom Waters.
Tréguer shows that the Southern Ocean is a source of
dissolved silica for the rest of the world ocean.
Patrick De Wever (2013 laureate of the Léon Lutaud
Prize) and co-authors review the distribution of radiolarite
facies (radiolarian rich cherts) around the former Tethys
Ocean. They argue that the deposition of these sediments is
a consequence of high productivity, rather than depth as
previously thought. They show that this implies a strong
role of monsoons, which have varied considerably in
amplitude as a function of the evolving geography of
continents (see cover illustration).
The fourth paper, by Benjamin Rotenberg (laureate of
the 2013 Michel Gouilloud–Schlumberger Prize) and
colleagues, reports recent multiscale modelling of trans-
port in clay minerals, starting from the molecular scale.
They address the physicochemical processes that underlie
the geochemical behaviour of fluids as they percolate and
are transported in pore networks and at the surface.
Upscaling all the way up to sample scale allows Rotenberg
et al. to capture phenomena such as electrokinetic
coupling. This may allow one in the future to attack
problems such as the modelling of hydrocarbons in oil and
gas shales.
The fifth paper, by Andrea Colombi and co-authors, led
by Michel Campillo (laureate of the 2013 Great Scientific
Prize of the Simone and Cino Del Duca Foundation of the
Institut de France), is concerned with the temporal
stability of the correlations of the coda of ambient seismic
noise. The Grenoble team extend their previous remark-
able work on how seismic noise can be used to reconstruct
coda waves (hence build high-resolution tomographic
images of the Earth’s interior at all space and depth scales),
in the presence of anisotropy in the incident field. They

Foreword / C. R. Geoscience 346 (2014) 273–274274develop a novel theoretical approach and apply it with
success to the Erebus volcano in Antarctica. The method
can be used to monitor volcanic activity at depth in quasi-
real time and in realistic field conditions.
Pascal Richet (laureate of the 2013 Yvan Peychès Prize
for Applications of Science to Industry) concludes this
thematic issue by taking us down to the atomic scale of
mantle minerals, emphasizing that major features of the
Earth can be understood as a consequence of the
differences in rigidity of the silicon–oxygen bonds with
respect to the silicon–oxygen–silicon linkages. This scale
requires the use of quantum-mechanical concepts. Richet
and Ottonello argue that this provides a rationale to
understand why SiO2 is enriched during magmatic
differentiation. They end the paper with illustrations of
their view of the Earth as a multiscale quantum-mechan-
ical system, with the effects of including alkalis, aluminium
or noble gases in the atomic structures of silicates.
Let me conclude by recalling that Comptes rendus
Geoscience welcomes not only highly innovative papers,
but also sound and timely reviews of subjects that appear
ripe for the exercise, and also proposals for thematic issues
on topics that may be of interest to a wide readership.
Finally, in closing, I, together with the whole Editorial
team, would like to acknowledge the remarkable work
done by Associate Editor Amaëlle Landais, who was until
this month in charge of papers concerned with the Earth’s
fluid envelopes and who has wished to move on to other
exciting scientific tasks. The Editorial team welcomes
Didier Roche who succeeds Amaëlle as of this issue of
Comptes rendus Geoscience.
