Dual-head Mapping

A dual-mount multibeam sonar installation is used to conduct extreme shallow-water surveys of intertidal seafloor to track morphologic change. This article contributed to by Heather Weiner, Brent von Twistern, Mike Brissette, Jonathan Beaudoin, and Amanda Hacking. The intertidal and nearshore zone is among the most ecologically productive and important zones to coastal resource management agencies. However,...

Aqua Bots

Above: The Z-Boat 1800 on a riverine hydrographic survey using sidescan sonar. Unmanned & Unlimited Unmanned aerial systems (UAS) get the lion’s share of media coverage, which is just not fair. Hardworking unmanned marine platforms, both surface and subsurface, have a lot to offer in the hydrographic surveying and inspection space. As a big bonus...
