Our hydrographic survey work is focused on inland ponds, lakes, rivers, and near shore in bays and harbors. Our earliest work consisted of pond soundings with a weight and tape working out of a jon boat for the phosphate industry. Over the years, we have developed a highly specialized approach to acquiring sounding data in harsh environments and difficult-to-access project sites.


Due in large part to demanding conditions in the phosphate industry, we have adapted our boats, trailers, and sounding equipment to meet these conditions. Our hydrographic services are carried out in a variety of compact and efficient platforms that range from 12’ and 16’ Carolina Skiffs to a 12’ canoe and an airboat for difficult-to-reach shallow waters. Sensors include a single beam Odom Hydrotrac Echo Sounder paired with a Trimble ProXR, and an R2Sonic 2020 Multibeam Echo Sounder with Coda F175 Motion Sensor and Trimble SPS461 GPS Heading Bundle.


Utilizing a custom designed and fabricated mount, we are able to easily swap sensors to meet project requirements. Data collection and office processing is accomplished with industry standard HyPack software.


Pickett is currently designing and testing an operational unmanned watercraft prototype to be an affordable, lightweight, easily deployed, highly maneuverable autonomous surface vessel. This vessel is being designed, in particular, to collect sonar data in acidic water retention ponds atop gypsum stacks, as well as other typical project conditions encountered in the course of hydrographic surveys.


The design and portability of the watercraft will make it easier to launch in areas with minimal boat ramps and able to traverse tighter areas inaccessible to manned watercraft.
