WASSP demo videos

The videos below demonstrate the multiple capabilities of the WASSP sonar when combined with the Olex plotter. Ranging from rapid detailed bathymetry collection through to detection of objects (for example fish and sub-sea pipelines).

1.1 Introduction| General overview of WASSP multibeam mapping

In this video we look at the basic operation of a WASSP multibeam sonar to collect bathymetric data and look at the effects of depth on the width of the sonar swath.

3.1 Water-column | Mapping water-column targets in real-time

The ability to detect and objects in the water-column is not even avalibel in all high-end hydrographic sonars. What makes the  WASSP/Olex combination unique is its ability to do this in real-time allowing objects to be detected without post-processing.

4.1 Backscatter | Demonstration of WASSP/Olex seabed discrimination

In addition to mapping out the depth of each of the 112 pings the WASSP also records the acoustic intensity (or “hardness”) of each ping. This allows areas of seabed with differing acoustic properties (i.e. rock, sand, mud) to be easily distinguished.

5.1 Habitat mapping| Example from Oregon rockfish and rocky reef

Combining all the capabilities of the WASSP and Olex systems provides the user with a highly effective too for habitat mapping. In this example we look at how rockfish can be detected with their associated rocky habitat near Stonewall Bank off the coast of Oregon.
