NSI

NSI has been conducting hydrographic surveys in North America since 1998, initially focusing on filling gaps in the NOAA bathymetric database. The company gained recognition for its work with ESPN, surveying lakes for BASS tournaments to create 3D models of the sea floor. Over the years, NSI has collaborated with notable organizations such as the History and Discovery channels, BP, and Exxon. Their services include surveying for dredging projects, monitoring oyster bars, and ensuring safe water depths in marina basins. Equipped with a custom-built survey vessel and advanced sonar technology, NSI provides accurate and detailed hydrographic data, including 3D renderings and spoilage estimates for dredging. They also handle all necessary permit work and quality control for dredging projects.
