Short summary
Ocean measurements currently rely on buoys for depth data and satellites for surface observations. We investigated combining these using data-driven approaches to reconstruct full 4D ocean profiles. Using an ocean model as ground truth, we simulated satellite surface data and ARGO profiles and then applied machine learning to predict complete temperature and salinity profiles. Results showed accurate predictions that matched simulation data and captured seasonal patterns.
