Internal Tides and Frontal Subduction (ITAFS)
Abstract
Internal Tides and Frontal Subduction (ITAFS)Our general objective is to improve our understanding on the high-frequency dynamics in the upper ocean with particular focus on internal waves in regions where they interact with 3D processes at sub and meso- scales such as fronts. In particular, we propose to study the nearsurfacecirculation and the thermohaline structure where strong fronts and intense internal waves/tides co-exist, for instance in the Alboran Sea (Western Mediterranean). The proposed measurements, using mainly Lagrangian platforms, will be integrated with, and complementary to, measurements collected by other CALYPSO DRI participants using otherplatforms (drifters, gliders, floats, research vessels). The study aims to separate the oscillatory vertical motions associated to the internal tide and 3D coherent circulation structures (such as subduction at fronts) producing net vertical transport between the surface and below thethermocline.
