NV5 Geospatial Expands Ocean Imaging with Purchase

May 18, 2021
The technology can be used to construct and maintain underwater power transmission lines, according to the company

With the recent acquisition of Geodynamics LLC, NV5 Geospatial has built a suite of solutions for geospatial surveys of deep water and near-shore environments.

The combination brings together complementary, advanced technologies – Geodynamics’ full-ocean depth sonar-based hydrographic and geophysical surveying with NV5 Geospatial’s topographic and bathymetric capabilities – to deliver detailed insights  for a variety of applications, including coastal management, flood monitoring, ecosystem protection, research and more.

"Surveys of the seafloor surface (multibeam, acoustic backscatter and side-scan sonar) and subsurface (chirp seismic, magnetometer) can be used to precisely position trenching / construction and electric or fiber optic cabling, and to monitor these lines post-construction. Additionally, remote underwater video inspection can be georeferenced to an as-built survey to assess cable burial, etc. and assess infrastructure periodically," Geodynamics CEO Sloan Freeman told T&D World.

Geodynamics is a pioneer in collecting and processing multibeam, single beam, sidescan, geophysical and acoustic backscatter hydrographic data in some of the most challenging coastal environments, including dynamic tidal inlets, high energy surf zones, and rapidly changing shoal systems that challenge navigation.

Geodynamics has completed large-scale hydrographic survey projects in the coastal and adjacent ocean areas of the entire United States, including detailed hydrographic surveys to support federal nautical chart updates in the Atlantic, Gulf of Mexico, and Great Lakes region for NOAA Office of Coast Survey.  

With a research focus on coastal geology, Geodynamics’ offshore geophysical surveys have supported mapping of marine minerals, benthic habitat and identification of potential submerged archaeological resources. To combine capabilities in ocean science and geospatial data services, NV5 Geospatial and Geodynamics created a joint venture in 2019. 

Working collaboratively as MarineGeoSpatial LLC, the partnership provided aerial and ship-based remote sensing for offshore/marine survey and data collection, mapping and data analysis, and marine enterprise GIS services. 

Geodynamics will operate as a unit of NV5 Global as part of the NV5 Geospatial group.
