Discussion

Observational analysis improved depth estimates in coastal environments, indicating global change impacts on monitoring.

Depth estimates improved by the generalised linear model, achieving a 42% reduction in RMSE.
Combining ten multi-temporal Sentinel-2 images enhances outcomes over single-image regression.
Outlier identification aids in reducing local anomalies, further refining accuracy in coastal analysis.
The findings highlight the potential for scalable implementation of improved satellite-derived bathymetry techniques.

Monteys et al. (2025) studied this question.
