Turbidity multibeam sonar soft sensing
Project description

Turbidity and SPM (suspended particulate matter) are currently being measured in the water column either in 1D (moorings, Niskin samples) or 2D (ADCP transects). However, a 3D approach is recommended, as the variability can be high, especially in the Belgian part of the North Sea. In TURBEAMS, we want to develop a methodology which leads to 3D SPM and turbidity imaging based on multibeam watercolumn data. We will build on the results of the Belspo-funded TIMBERS project by collecting co-located datasets of the acoustic instruments of the RV Belgica and in-situ SPM and turbidity sensors. This will result in a number of empirical relationships, which will allow the conversion of multibeam backscatter values into quantitative SPM and/or turbidity information. As such, a relatively fast 3D image can be obtained, which would be extremely relevant for science and industry.
