Our 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

DVLs provide crucial information to ROV operators and enable subsea and surface vehicles in GPS-denied environments to navigate reliably underwater.

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

Comprehensive knowledge of the sea state near coastal communities informs coastal protection measures and safe coastal operations.

Operations & Energy

Knowledge of metocean conditions is crucial to ensure safety and efficiency of personnel working offshore on projects from feasibility studies to laying cable.

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.

Doppler Dynamics - Navigation

The morning sessions will introduce the fundamentals, ensuring everyone has a shared level of understanding before we explore practical DVL applications and how DVLs can be used most effectively to support subsea navigation.   After lunch, we will head out on the water for a practical demonstration of DVL-aided surface navigation in a GNSS-denied environment, delivered in collaboration with Exail.   There will be regular breaks throughout the day, providing plenty of opportunities to network and speak with Nortek experts. Lunch and refreshments will be provided.   Interested in oceanography and ADCPs? We’re also hosting a dedicated Doppler Dynamics – Oceanography event on November 18th - follow this link to register

Doppler Dynamics - Oceanography

The morning sessions will introduce the fundamentals, ensuring everyone has a shared level of understanding before we explore practical tips for maximising deployment success. We will then review recent developments across Nortek’s ADCP product range - including the Gen 2 AWAC, Aquadopp and Vector - and offer a glimpse of what’s coming next.   After lunch, we will split into two groups. You can choose to: Join a vessel-based practical demonstration of a vessel-mounted ADCP, followed by a session on processing the collected data; or Remain at the NOC for an introduction to ADCP quality assurance, quality control and data post-processing using Ocean Contour. There will be regular breaks throughout the day, providing plenty of opportunities to network and speak with Nortek experts. Lunch and refreshments will be provided.
