Profiling Current Meter

The SeaGuard DCP (Acoustic Doppler Current Profiler) measures currents and can be extended with wave direction, oxygen, conductivity, turbidity, temperature, and serial sensors.

It features innovative development of the acoustic profiling capacity and an exceptional ability to collect high quality current information on moving and tilting moorings.

Available as a self-recording current meter, it also integrates unique real-time features to meet your application needs.

The SeaGuardII Acpustic Doppler Profiler, is a smart data hub that combines the SeaGuard electronics with the advanced management firmware of the Aanderaa SmartGuard data hub.

The DCP is a 600kHz frequency profiler with multi-sensor capability for acoustic doppler profiling. By design, we offer increased deployment time, optimized configuration flexibility and unique features to cope with demanding upper ocean environments.

Optional parameters are available using the Aanderaa range of smart sensors that include temperature, pressure, conductivity, oxygen, wave, tide and turbidity. In addition the SeaGuardII Profiler has 4 analog inputs, 2 serial ports with power control and direct connection for real time data transmission output.

Ocean Currents

Ocean water currents are driven by winds, tides and density differences. The ocean circulation regulates the earth's climate by transporting heat. The flowing water affects offshore and coastal construction and also carries particles, animals, plants, nutrients, pollutants and dissolved gases. The acoustic doppler technique has become the preferred technology for most users measuring ocean current, because it is robust, needs no calibrations, can be used for both point (RCM) and profiling (Acoustic Doppler Current Profiling) measurements and is basically insensitive to fouling.

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.
