Nortek’s product portfolio ranges from wave measurement systems to single-point tur- bulence sensors and oceanic current pro? lers. Our product range covers four themes: ocean waves, ocean currents, tur- bulent ? ow and subsea navigation.

A notable new innovation from Nortek is the Nortek Eco, a fully functional Acoustic Doppler Current Pro? ler (ADCP) not much bigger than a coffee mug. Eco makes ADCP data available to those who historically may not have had the budget, equipment, or experience to use ADCPs, but would

ROS has 30+ employees and its product line includes underwater video cameras, lights, rugged pan and tilt positioning systems, video inspection systems and control systems manufactured primarily for the oceanographic, nuclear and defense industries.

For 2021 ROS has developed two new products designed for deep ocean applications. The SeaStar is a high-powered, lightweight compact LED light that delivers 10,000 lumens output with full-range dimming capability. The SeaStar is completely Field Serviceable and available with ? ood or spot re? ector options. It is depth rated to 6,000 meters. The
