meeting the 24 th of June in Marseille. Discussion on
the final proposal to be submitted in September 2002
GENERAL
POINTS : KEOPS (Kerguelen compared
study of Ocean and Plateau in surface water) is a project
related to the french program PROOF PROcessus biogéochimiques
dans l'Océan et Flux) of INSU
(Institut National des Sciences de l'Univers). Most of
the objectives of KEOPS are also in agreement with the
international program SOLAS.
KEOPS will improve the knowledge of biogeochemical cycles
in the Southern Ocean. Mainly based on process studies
it will contribute to a better understanding and prediction
of the response of this large HNLC area to the global
climatic change. Particularly KEOPS will study the effect
of natural iron fertilisation of the ocean by the Kerguelen
plateau, on the biological pump of CO2
and on the cycles of other chemical compounds relevant
for climate. A multidisciplinary approach will be used,
coupling physic and biogeochemistry. A strong link with
the modellers will be also established. KEOPS will provide
parameterisations for different kind of biogeochemical
models. The project will federate French teams and will
be largely open to foreign collaborations. Two cruises
are planned on board Marion
Dufresne (IPEV
Institut Polaire Français - Paul-Emile Victor).

Chlorophyll concentrations (SEAWifs data) over the
Kerguelen plateau and in the surrounding ocean during
january 1999. The bathymetry is also plotted (Blain et
al., 2001). Blain S., Tréguer P., Belviso S., Bucciarelli
