    <p style="text-align:justify">The main scientific objectives of the cruises are threefold:</p> <ul> <li style="text-align: justify;">to asses the large scale circulation in the Western Basin, evaluating the water masses and the fluxes at different key point in the basin (The North Current, The East and West Corsica currents, the Balearic front, Algerian Basin). The final goal was numerical modelling assessment.</li> <li style="text-align: justify;">to identify and follow peculiar mesoscale structures such as surface eddies, modal weddies, submesoscale coherent vortices (SCV) meanders or filaments and explore the signature on the sea surface height (altimetry) and the acoustic impact (sound propagation).</li> <li style="text-align: justify;">to observe and interpret the submesoscale dynamics such ageostrophic stirring, symmetric instabilities, mixed layer instabilities, subduction and convection.</li> </ul> <p style="text-align:justify">The Protevs2015_leg2 campaign ran from 21 March to 10 April 2015 aboard the BHO Beautemps-Beaupré in the north-western Mediterranean basin. It focuses on aspects of physical oceanography (hydrology and dynamics). The main one is the dynamics of the North Current from the Balearic Sea, downstream, up to its roots upstream in the Ligurian Sea. The measurements attempt to capture not only the structures and characteristics of the mesoscale of the northern current, but also the sub-mesoscale associated with or at least near the northern current.</p>

    Studying the Messinian Salinity Crisis on the Balearic promontory and using its markers to assess post-crisis vertical movement and the reactivation of the region. 1) Fine-scale continuous mapping of evaporites from land to the deep basin in order to answer the following question: What is the spatial-temporal variability of evaporites of the Balearic Promontory (evaporites on land, very thin or thick evaporates at sea)? 2) Using the Messinian as a marker of syn- and post-MSC deformations; isolating recent movements from previous deformations and quantifying them in order to reproduce the paleo-bathymetry and paleo-connections during the crisis. Were the evaporites in shallow basins continuous with evaporites in deeper basins before the recent deformations? The related project is 'Action Marges', Mediterranean study site.
