For more than a decade, Oceanscience, a company based in Carlsbad, California, has supplied the oceanographic community with deployment platforms for environmental monitoring instrumentation. Of course, an RC boat bought at a toy store would typically be too small and underpowered to carry the required instruments. That is when a small, remote-controlled (RC) boat can be a very valuable tool. In the case of hydrographic surveys of lakes, ponds, reservoirs, rivers, and streams, the depth of the water, rocks, and strong currents may make it impossible or too dangerous for surveyors to wade in, while insufficient overhead clearance, very shallow spots, and other obstructions may make it impractical for them to use a boat. Surveyors in parched California measure sedimentation levels in a reservoir using a small, remote-controlled boat integrated with a survey-grade RTK.īefore they even start taking measurements, surveyors often have to deal with such practical challenges as how to access and move around in their survey area-which may be rocky, filled with dense vegetation, or obstructed by construction.
