Satellite–Argo Reconstruction of the Mesoscale-Eddy Sound-Speed Field and Its Effect on Towed-Array Gain: A Differentiable Framework with Bounded Acoustic Feedback

We reconstruct the four-dimensional sound-speed field of mesoscale eddies from satellite sea-level anomaly and sparse Argo profiles with a geostrophically constrained coordinate network, and connect it to array-level acoustics through a differentiable parabolic-equation model and...
