Acoustic suspended sediment profiler – research model
The AQUAscat® 1000R represents a new generation of high frequency acoustic instrumentation. It has applications in sediment transport studies, including measurement of suspended sediment profiles, precision altimetry, dredge plumes and turbulence.
The AQUAscat transmits pulses of high frequency sound on up to four transducers, each of which may operate at a different frequency. It measures the sound scattered by sediment or other suspended materials at discrete spatial intervals programmable from 2½ millimetres to 4 centimetres. For altimetry, this may span a few tens of centimetres; for monitoring sediment suspension profiles, a total range of around 1- 2 metres is typical; while dredge plume estimation may extend to 10 metres. The instrument is supplied in a subsea housing suitable for long-term unattended deployments. Batteries for various deployment schedules are available to order.
