Setup
The Nortek team will assist you with selecting custom sensors for your buoy and appropriate sampling schemes for your Signature ADCP. Alize buoys are made to order and adapted specifically for your project requirements.
Deployment
Our team will also assist you with deployment, including designing moorings, assisting with transportation and configuring your ADCP. The Alize requires more complex deployment equipment than our Zephyr buoy due to its larger size and capabilities.
Data
Data are transmitted in real-time through cellular network or Iridium and hosted by Nortek. Our expert team will take care of data processing and quality control, providing you with high-quality data you can rely on.
