A subregional shallow water bathymetry derivation method for coral reef using ICESat-2 and Sentinel-2 combined with sediment information

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
The bathymetric data is of great significance to coral reef protection. Traditional measurement methods have low efficiency, high cost, and are easily affected by natural conditions.

Depth from Satellite Images: Depth Retrieval Using a Stereo and Radiative Transfer-Based Hybrid Method

open access: yesRemote Sensing, 2018
Satellite imagery is increasingly being used to provide estimates of bathymetry in near-coastal (shallow) areas of the planet, as a more cost-effective alternative to traditional methods.

Integrating multibeam echo sounder and satellite-derived bathymetry for mapping of shallow coastal water [PDF]

open access: yes
Echosounders are the most used depth acquisition equipments in bathymetry surveys. Despite its widespread usage, the vessels that are equipped with echosounders and their necessary components are not able to enter certain areas where the water depth is ...

Improving Satellite-derived Bathymetry

open access: yes, 2016
Bathymetry is traditionally acquired using singlebeam or multibeam echosounders. This method produces accurate depth measurements along transects but is constrained by operating cost and an inability to survey in very shallow waters. Airborne Lidar is able to produce accurate bathymetric information over clear waters at depths up to 70m, but can be ...
