Tellus: Series A, Dynamic Meteorology and Oceanography, 2022 Data assimilation methods have been proposed as a technique for reconstructing ocean bathymetry from observations of surface waves. To better understand this technique, we use second order adjoint (SOA) variational analysis to derive the sensitivity of ...

S2SHORES: A PYTHON LIBRARY FOR ESTIMATING COASTAL BATHYMETRY
Coastal Engineering Proceedings, 2023 Understanding coastal zone dynamics covering large spatial and dense temporal scales is paramount to understand and mitigate emerging coastal issues relating to climatological changes. However, the uncertainties on the coastal zone risks are still too large to predict effectively impacts on an overall increasing coastal population.

cBathy: A robust algorithm for estimating nearshore bathymetry [PDF]
Journal of Geophysical Research: Oceans, 2013 A three‐part algorithm is described and tested to provide robust bathymetry maps based solely on long time series observations of surface wave motions. The first phase consists of frequency‐dependent characterization of the wave field in which dominant frequencies are estimated by Fourier transform while corresponding wave numbers are derived from ...

Tellus: Series A, Dynamic Meteorology and Oceanography, 2021 Accurate mapping of ocean bathymetry is needed for effective modelling of ocean dynamics, such as tsunami prediction. Available bathymetry data does not always provide the resolution to model such nonlinear waves accurately, and collection of accurate ...

Neural Network Normal Estimation and Bathymetry Reconstruction From Sidescan Sonar
IEEE Journal of Oceanic Engineering, 2023 Sidescan sonar intensity encodes information about the changes of surface normal of the seabed. However, other factors such as seabed geometry as well as its material composition also affect the return intensity. One can model these intensity changes in a forward direction from the surface normals from bathymetric map and physical properties to the ...
