Argonaut-XR, Chile


Argonaut-XR, Belguim

Argonaut-XR, Brazil

The Argonaut-XR offers exceptional value for near shore deployments in less than 40 m of water. Designed specifically for mounting on the bottom of a river, channel, or harbor, the XR features a special mode that automatically adjusts one of its measurement cells for changing water level. Its small size, rugged build, and flexible system architecture make the XR attractive for both real-time operation and autonomous deployments.

The MultiCell Feature

MultiCell is an innovative way of current profiling. Combining all the benefits of classical current profiling with the dynamic AutoTide feature, users have the best of both worlds. The Additional dynamic velocity cell adjusts with changes in water level.

Argonaut-XR Considerations for Sea Cage Aquaculture

Considerations for Sea Cage Aquaculture

The use of offshore cages, or pens, to culture marine finfish has been used successfully to culture a number of species for many years. Success with cage systems is common in Australia, Norway, and Chile with cage culture being used since the 1950’s in some regions.The consumer popularity of marine finfish in recent years has led to an increase in the demand for the culture of traditional species and also experimentation with several newer species. This popularity has led to an increased demand for marine aquaculture sites in several areas.
