Heteroscedastic uncertainty quantification for GGM-inverted bathymetry: A zero-mean Laplace distribution framework

The Gravity-Geologic Method (GGM) is widely used to predict bathymetry from satellite-derived gravity anomalies, yet a robust framework for quantifying the uncertainty of its predictions is lacking. Traditional approaches often assume homoscedastic, Gaussian-distributed errors, which do not hold in complex terrains. Th...
