| Several recent studies reveal the importance of submesoscale. The submesoscale dynamics is strongly ageostrophic, leading to intense vertical velocities and intense vertical buoyancy fluxes. Here, we study the role of (sub)mesoscale structures during deep convection events in the North-Western Mediterranean sea. By using numerical configurations at different spatial resolutions and adapted scale separation methods, the impact of submesoscale features is quantified during the different phases of the intense convection event of winter 2012-2013. |

| The exploitation of offshore mussel farms is becoming important throughout the world, but monitoring this activity remains a difficult task. Here, we propose a specific method for this purpose. A total of 140 long-lines were monitored on a mussel culture ground in the French Mediterranean Sea during four experimental surveys deploying multibeam sonar devices mounted on poles (Reson Seabat 6012, 455 kHz) on small boats. This allowed geo-referenced observations to be made of the submerged mussel long-lines, as well as three-dimensional (3D) drawings of the long-line structures and the sea bed shapes, using long-line longitudinal sonar sampling. Three sonar data-analysis methods were applied: (i) direct two-dimensional (2D) visual interpretation of raw sonar... |
