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 Responsein the Mediterranean Experiment (2010-2020),

Towards an identification of deep-sea bioluminescent macro-organisms close to the ANTARES detectors
In collaboration with S. Escoffier, J.J. Aubert (CPPM)A.S. Cussat-Legras, A.F. Yao (COM)
From literature data
From PM of ANTARES
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).
