Measurement of micro-bathymetry with a GOPRO underwater stereo camera pair
Val E. Schmidt,Yuri Rzhanov +1 more
- 01 Oct 2012
TL;DR: In this article, a GO-PRO underwater stereo camera was used to measure the seafloor topography of a patch of seaflores producing a point cloud with a spatial data density of 15 measurements per 3 mm grid square and an standard deviation of less than 1 cm.
A detailed seabed signature from Hurricane Sandy revealed in bedforms and scour
Arthur C. Trembanis,Carter DuVal,Jonathan Beaudoin,Val E. Schmidt,Doug Miller,Larry A. Mayer +5 more
TL;DR: In this article, a set of high-resolution before and after storm measurements of seabed morphology and in situ hydrodynamic conditions (waves and currents) capturing the impact of the storm at an inner continental shelf field site known as the Redbird reef was obtained.
Parameter identification of a nonlinear model: replicating the motion response of an autonomous underwater vehicle for dynamic environments
Alexander L. Forrest,Alexander L. Forrest,Remo Cossu,Remo Cossu,Zhi Leong,Dev Ranmuthugala,Val E. Schmidt +6 more
TL;DR: The calibrated model is able to compute the position of the AUV within an uncertainty range of around 1.5% of the distance travelled, significantly improving the localisation accuracy.

Automated optimal processing of phase differencing side-scan sonar data using the Most-Probable Angle Algorithm
Val E. Schmidt,Thomas C. Weber,Arthur C. Trembanis +2 more
- 01 Oct 2012
TL;DR: In this paper, the authors developed a method for the automated processing of phase-differencing side-scan sonar data, which produces seafloor estimates and related uncertainties optimized for the survey application.
Underwater radiated noise levels of a research icebreaker in the central Arctic Ocean.
TL;DR: Underwater radiated noise signature was characterized in the central Arctic Ocean during different types of ice-breaking operations, including transit in variable ice cover, breaking heavy ice with backing-and-ramming maneuvers, and dynamic positioning with the bow thruster in operation.
