| Vertical velocities can be estimated indirectly from in situ observations by theoretical frameworks like the ω‐equation. Direct measures of vertical exchanges are challenging due to their typically ephemeral spatiotemporal scales. In this study we address this problem with an adaptive sampling strategy coupling various biophysical instruments. We analyze the 3‐D organization of a cyclonic mesoscale structure finely sampled during the OSCAHR (Observing Submesoscale Coupling At High Resolution) cruise in the Ligurian Sea during fall 2015. The observations, acquired with a Moving Vessel Profiler (MVP), highlight a subsurface low‐salinity layer (≃ 50 m), as well as rising isopycnals, generated by geostrophic cyclonic circulation, in the structure's center.... |
