The Ocean Science Matrix

The Ocean Science Matrix covers a diverse range of disciplines focused at studying the world's oceans. It covers hydrography and applications related to physical oceanography, marine biology, coastal meteorology and is ultimately linked to gaining a better understanding of the processes affecting global climate change.

Sonardyne's acoustic navigation, positioning and remote sensing systems are relied upon by the world's leading scientific institutes for the recovery of valuable data and instrumentation.

Long Range Tracking

With proven results tracking targets to ranges of greater than 6,000 metres, Sonardyne's 6G® USBL technology provides techniques for even the most extreme subsea positioning requirements. 6G® transceivers offer guaranteed performance in the harshest environments in which they operate.

Large array transceivers optimised to receive signals arriving within a ±50° cone are ideally suited to tracking ROV and manned submersibles to the deepest of ocean bottoms. With Sonardyne's unique 'ping stacking' technology, the systems offer fast position update rates (one second independent of water depth) tracking of up to10 targets at full ocean depth.

 

Optimised USBL

Ocean science often involves the requirement to survey the seabed over extremely large areas. For these surveys using vessel mounted sensors, Sonardyne's low latency Lodestar AHRS sensor installed as part of a 6G® USBL system can also be used for vessel motion compensation of all vessel mounted sensors. For detailed surveys requiring the deployment of towed vehicles, Sonardyne's Inverted USBL techniques have been proven to offer superior positional accuracy over the longest of laybacks.

 

Autonomous Monitoring

In order to gain a comprehensive understanding of the seabed, position and environmental monitoring is required. If the area is to be monitored over a long period of time, a network of Sonardyne's new 6G® Autonomous Monitoring Transponders can be deployed for long periods in order to collect accurate sensor measurements without the costly requirement of a dedicated operating vessel to remain on location.

 

Data Telemetry

Wideband 2 telemetry in 6G® products enables them to be used for navigation with integrated telemetry one day or pure telemetry another day. The signal processing advances enable robust performance even in difficult long shallow channels such as telemetry of ADCP data across estuaries.

Deploying and recovering sensor packages is made easy by the comprehensive range of release and actuation techniques available which can be controlled and tracked using Sonardyne 6G® systems. For relocation activities, explore the range of simple, robust range and direction finding techniques.
