SeaGuard Sensor String

The Aanderaa SEAGUARD® Sensor String Systems are complete and flexible subsea observatories for measurements of e.g. dissolved oxygen, conductivity, temperature, current, pressure and tide.

SEAGUARD® String Logger
The Aanderaa SEAGUARD® String Logger is the basic module of the SEAGUARD® Sensor String System.The SEAGUARD® String Logger is capable of handling a large number of sensors. Data is stored on an internal SD-card or transferred in real-time via cable.  

SEAGUARD® Sensor String
The new Aanderaa SEAGUARD® Sensor String is designed to be connected to the SEAGUARD® String Logger.The SEAGUARD® String System can hold up to 25 AiCaP Sensors. Real-time communication and control is available using the Aanderaa Real-Time Collector.

The Aanderaa Tide sensors are compact fully integrated sensor for measuring the tide conditions.

Ocean Waves

Surface waves are formed by winds either locally as "wind waves" with shorter periods, or further away as “swell" with longer periods. A rare case of extremely long period of ocean waves are tsunamis from e.g. earthquakes and landslides. Because ocean waves can travel far and can contain high energy it is important to measure ocean waves to understand their impact on shipping fishing, tourism, constructions, shorelines, water mixing, sediment resuspension, gas exchange etc.
