Acoustic Seabed Classification


Acoustic Seabed Classification

Seabed classification based on acoustic properties can be divided into two main categories; seabed surface and seabed sub-surface.

Seabed surface classification is concerned primarily with distinguishing habitat characteristics (e.g. hard, soft, mud, sand, clay, cobble) to the sampled area. The seabed class can be combined with other acoustically (or other method) derived information about the area, such as fish distribution and abundance or vegetation characteristics, to establish habitat groups based on the associations.

Sub-surface seabed classification is commonly referred to as Sub-bottom profiling and is generally used for geological assessment of the sub-surface characteristics, down to hundreds of meters, as necessary in the exploration for oil deposits.
