The spatial information of the seabed biodiversity is important for marine zone management in Australia. The biodiversity is often predicted using spatially continuous data of seabed biophysical properties. Seabed hardness is an important property for predicting the biodiversity and is often inferred from multibeam backscatter data. Seabed hardness can also be inferred based on underwater video footage that is, however, only available at a limited number of sampled locations. In this study, we predict the spatial distribution ...
