Abstract/Description: In this chapter we provide a description of an intense ocean front and an anomalous anticyclonic eddy in the Western Mediterranean. We use observations from two multi-platform experiments carried out in the eastern Alboran Sea and in the northern Balearic Islands. We diagnose mesoscale vertical motion ( 1-10m/day) associated with these ocean structures using quasi-geostrophic dynamics. A unique characteristic of both field experiments is the combination of conventional in situ measurements from ships with high-resolution observations using autonomous underwater vehicles (gliders). For the eastern Alboran Sea, we also use a high-resolution numerical model that is initialized with hydrographic data (0.5-1 km resolution) from gliders. Numerical simulations show that lateral buoyancy gradients are large enough to trigger submesoscale mixed layer instabilities. Results from the model illustrate that a mixed layer tracer subducts to form vertical intrusions extending to depths of 80-90 m, which is in agreement with remarkable subduction events of chlorophyll and oxygen captured by ocean gliders.
