The proposed research is based on the monitoring of the long term evolution of the North Western Mediterranean Sea with glider repeat-sections carried out in the framework of the ALLENVI/INSU/ SOERE MOOSE (http://moose-network.fr), INSU/MISTRALS (http://www.mistrals-home.org), and EU FP7 PERSEUS (http://www.perseus-net.eu).  The objective is to monitor the oceanographic variability (physical and biogeochemical) of the north western Mediterranean Sea, over a continuum of spatial and temporal scales. Two cross-basin repeat-sections with a repeat rate of about 10-20 days allow to monitor the main circulation features (Northern Current, North Balearic Front, Western Corsica Current) on a regular basis, as well as major processes such as winter intermediate and deep water formations and vernal blooms. The gliders regularly visit MOOSE moorings for cross-calibration purposes and to explore the variability around these moorings.
i) T00 is a repeat-section between Nice and Calvi passing by the MOOSE mooring DYFAMED located in the central Ligurian Sea
ii) T02 is a repeat-section between Marseille and Menorca passing by the MOOSE mooring LION located in the center of the deep convection area
