Ifremer®
Evidence for Prestige fuel oil (bio)degradation at
2400 m water depth after 2 years of incubation.
Changes in the bacterial community structure likely
reflect an adaptation of bacterial communities to the
contamination in association with a probable selection
of hydrocarbonoclastic bacteria. This point is supported
by the isolation of various hydrocarbonoclastic bacteria
from the ANTARES station.
macrobenthic recolonisation and sediment reworking
activity do not seem to have been affected by the
contamination.

• Develop a tool for real time multi disciplinary science
• Flexibility to welcome any generic sensor
• Adjust time scale of maintenance according to sensors
characteristics
• Export the concept to other cabled site. This proposal intends
to demonstrate the necessity of well defined calibration
procedures. The final goal of the methodology is to be able to
compare measurements on different existing ESONET sites.

“MISTRALS”
(Mediterranean Integrated STudies at Regional And Local Scales)
“MISTRALS” is a decadal project of systematic Observation.
It aims at understanding at the global change impact at a basin scale on the the
ecosystem functioning.
Using a multidisciplinary approach from 2010 till 2020.
It aims at simulating the mediterranean basin evolution for the next century in term of
human habitat, sustainability, and propose scenario for a better adaptation and/or
mitigation.
« MISTRALS » is a French initiative; to initiate a Euro-mediterranean project involving all
the Mediterranean countries.
MERMEX: Marine Ecosystems Response
in the Mediterranean Experiment (2010-2020),
(https://mermex.com.univ-mrs.fr/)
Response of the Med. Ecosystems to global change including temperature increase and
anthropogenic pressure (contaminants). This project is a component of ‘Chantier Mediterranée
Programme’ which comprises atmospheric chemistry (Charmex), hydrometeorology (HYMEX),
Biodiversity (Biodivmex), Paleomex…

Towards an identification of deep-sea bioluminescent
macro-organisms close to the ANTARES detectors
From literature data
From PM of ANTARES
In collaboration with
S. Escoffier, J.J. Aubert (CPPM)
A.S. Cussat-Legras, A.F. Yao (COM)
The idea was to combine literature and PM of ANTARES data to assess the incidence of
events and the identification of the organism (at the group level).
