Hydrography encompasses the full spectrum of practices from single beam sonar echosounding to deep ocean current profiling. This includes sonar imaging, underwater inspection, and mapping. In addition to representing many of the leading manufacturers in the hydrographic survey industry, Seafloor maintains the largest and most up-to-date rental pool of multibeam echosounders, ancillary hardware, and software systems in the United States.

No longer does the land surveyor need to don waders and a rod extension to collect elevations under water. Utilizing Seafloor's range of portable echosounders designed to work with existing land survey data collection systems, fast, high-resolution, and accurate mapping from a small boat is made easy. With our systems, the transition between land survey and hydrographic survey is seamless and will save you time on your project.


Seafloor offers an array of monitoring, controlling, and information hardware / software solutions for dredging applications. Ours and third-party products are your underwater eyes for projects ranging from small bucket to large trailing suction hopper dredge operations.
