Measurement of micro-bathymetry with a GOPRO underwater stereo camera pair
A GO-PRO underwater stereo camera kit has been used to measure the 3D topography (bathymetry) of a patch of seafloor producing a point cloud with a spatial data density of 15 measurements per 3 mmExpand

Automated optimal processing of phase differencing side-scan sonar data using the Most-Probable Angle Algorithm
Phase-differencing side-scan sonar systems produce co-located bathymetry in addition to each side-scan amplitude measurement. Bathymetric soundings are calculated from the range to each measurementExpand
