Short summary
Satellites do not measure every part of the ocean at every moment, so maps of ocean surface height often have gaps. We developed a computer method that learns from scattered satellite measurements to fill in these gaps while keeping the reconstructed patterns smooth and physically plausible. Tests with real and simulated data show that the method improves regional ocean surface maps and better preserves important ocean features, supporting future monitoring of ocean change.
