Abstract:
The CALYPSO ONR DRI is an international project aiming to understand the 3D Lagrangian pathways and processes by which water gets from the ocean surface to depth near strong fronts. As part of this project, two targeted drifter experiments were conducted in 2018 and 2019 that consisted of arrays of drifters with drogues at different depths, spanning the upper part of the water column from 1 m down to 50 m. Here we present the analysis of the collected multi-layer drifter data. Our analysis include divergence and vorticity estimates at different depths, vertical velocities, spectral analysis, as well as estimates of various terms in the vorticity balance.
