A new technique based on mini-UAS for estimating water and bottom radiance contributions in optically shallow waters [PDF]

, 2015
The mapping of nearshore bathymetry based on spaceborne radiometers is commonly used for QC ocean colour products in littoral waters. However, the accuracy of these estimates is relatively poor with respect to those derived from Lidar systems due in part

Pan-European Satellite-Derived Coastal Bathymetry—Review, User Needs and Future Services

Frontiers in Marine Science, 2021
Low-lying coastal zones are home to around 10% of the world’s population and to many megacities. Coastal zones are largely vulnerable to the dynamics of natural and human-induced changes.

An Improved Gridded Bathymetric Data Set and Tidal Model for the Maldives Archipelago

Earth and Space Science, 2021
The Maldives faces a unique range of environmental challenges. While the country is almost entirely dependent upon oceanic resources with more than 99% of the area covered by ocean, the absence of a suitable bathymetric map of the seafloor of the ...

Revised Pacific-Antarctic plate motions and geophysics of the Menard Fracture Zone [PDF]

, 2008
A reconnaissance survey of multibeam bathymetry and magnetic anomaly data of the Menard Fracture Zone allows for significant refinement of plate motion history of the South Pacific over the last 44 million years.

Use of remotely-derived bathymetry for modelling biomass in marine environments [PDF]

, 2013
The paper presents results on the influence of geometric attributes of satellite-derived raster bathymetric data, namely the General Bathymetric Charts of the Oceans, on spatial statistical modelling of marine biomass. In the initial experiment, both the

Bathymetry Estimation from Satellite Altimeter-Derived Gravity Data

, 2023
Bathymetry underpins all marine and ocean research. It is common knowledge that there is a global deficit of high-resolution bathymetry based on modern acoustic techniques. Satellite altimetry enabled modeling of the global seafloor topography and revealed new morphological features in the unmapped areas of the oceans and seas.
