Shallow-water Seafloor Topography Refinement Using Sentinel-2 and Multi-Source Gravity Data via a Depth-Stratified XGBoost Approach

Shallow-water depth data serve as the essential foundation for marine spatial planning and coastal engineering projects. However, due to the attenuation of spectral signals, traditional retrieval of shallow-water seafloor topography struggles to maintain high accuracy in highly turbid waters and deeper areas. Further...

Machine Learning-Driven Lateral Density Variation for High-Precision Bathymetry: Central-Northern South China Sea

By coupling neural network-derived density modelling with physically rigorous inversion, the approach overcomes limitations of uniform-density assumptions while retaining interpretability, providing an efficient and reliable approach to high-precision seafloor mapping in geologically complex regions.
