Numerical modeling and simulation technique in time-domain for multibeam echo sounder
A Multibeam Echo Sounder (MBES) is commonly used for rapid seafloor mapping. We herein present a time-domain integrated system simulation technique for MBES development. The Modeling and Simulation (M&S) modules consist of four parts: sensor array signal

Maximum A Posteriori Resampling of Noisy, Spatially Correlated Data [PDF]
In any geologic application, noisy data are sources of consternation for researchers, inhibiting interpretability and marring images with unsightly and unrealistic artifacts. Filtering is the typical solution to dealing with noisy data.

Improved Arctic Ocean Bathymetry Derived From DTU17 Gravity Model
The existing bathymetry map of the Arctic is a compilation of ship soundings and digitized contours. Due to the presence of all‐year sea ice, costly operations and political restrictions, dense and full coverage of the Arctic is not possible, leaving ...
