Reliable sensors and integrated measurement systems for marine environments
We equip marine researchers and subsea engineers with advanced acoustic technology. From standalone Doppler sensors to integrated measurement systems, we deliver the precise data and reliable navigation required for complex underwater operations.
Our six focus areas
Marine science and research
Oceanographers, marine scientists and government researchers require innovative oceanographic equipment that gives them data they can trust.
Marine autonomy
Oceanographers, marine scientists and government researchers require innovative oceanographic equipment that gives them data they can trust.
Defense and security
Trusted by leading defense contractors, Nortek’s DVLs enable accurate subsea navigation for AUVs, ROVs, USVs, and diver systems in critical missions.
Coastal engineering
Knowledge of metocean conditions is crucial to ensure safety and efficiency of personnel working offshore on projects from feasibility studies to laying cable.
Operations & Energy
Comprehensive knowledge of the sea state near coastal communities informs coastal protection measures and safe coastal operations.
Marine resources
Informed management of fisheries, ocean ecosystems, kelp farms and more contributes to sustainable human development.
Our technology is used in oceanography and subsea navigation
Nortek’s advanced Acoustic Doppler Current Profilers (ADCPs) and Doppler Velocity Logs (DVLs) use the Doppler effect to measure motion in the marine environment. ADCPs are used to measure oceanographic processes as seen in currents and waves, while DVLs help subsea vehicles to navigate underwater.
DVL 333 Surface
Oceanographers, marine scientists and government researchers require innovative oceanographic equipment that gives them data they can trust.
