Aanderaa products have been used for environmental research, oceanographic research, hydrographic monitoring, river and lake research, as well as climate research for many years.

Our Seaguard platform and expanding line-up of smart sensors may be used either as a self-recording instrument, or as a real-time Met-Ocean observing network. This versatility is available without the extra cost associated with a custom solution.

AADI systems for the environmental research communities include Seaguard RCM/CTD, Recording Doppler Current Profiler, automatic weather stations, wave and tide stations and buoy systems. Stand-alone sensors are available for measuring parameters such as conductivity, temperature, pressure, oxygen, wave and tide, currents and water level.
