Inconsistent interface measurements and low resolution in satellite altimetry hinder precise identification of subsurface oceanic disturbances. Accurate detection prevents structural stress on marine infrastructure and improves navigational safety.

Unreliable prediction of subsurface acoustic properties and dynamic water levels leads to operational failures in marine navigation and sonar performance. Improving predictive accuracy reduces uncertainty in complex underwater environments.

Uncertainty in ship freeboard and state information leads to navigation risks and loading errors. Precise vertical reference data improves maritime safety and operational efficiency.

Dynamic environmental factors like typhoons and surges create non-linear noise in marine elevation data. Mitigating these disturbances ensures the accuracy of vertical kinematic measurements in volatile sea states.

Acoustic and visual signals suffer from severe distortion and attenuation in aquatic environments. Improving ranging and depth estimation precision overcomes physical barriers to identifying and tracking submerged objects.
