MBES transducers transmit multiple high frequency pulses of sound from beneath a vessel in a fan shape down to the seabed. The amount of energy reflected back to the vessel for each pulse of sound is termed the backscatter. The amount of energy returned will depend on many factors including seabed roughness and sediment composition. For example, muddy seabed will return a weaker signal than a harder, gravelly or rocky seabed. As such, backscatter data can be used as a proxy to understand the characteristics of the sea floor, including the sea floor hardness, roughness and surficial sediment characteristics. The primary purpose of the backscatter datasets acquired is to aid the classification of the seabed into sediment types in order to aid marine spatial planning, ORE industry and habitat conservation. Data is available as a 32 point floating singleband geotiff. There are two different geotiffs of different resolutions available to download; 10m and 40m.
