Seabed Sediment Classification using Multifrequency Backscatter
IOP Conference Series: Earth and Environmental Science, 2023 Abstract Seabed sediment serves as an important metric for assessing marine ecosystems. Different sectors, including the development and utilization of marine resources, marine engineering, environmental research, marine fisheries, and maritime navigation safety, all depend on the classification and identification of different forms of ...

Seabed Classification Using Multibeam Echosounder Measurement Data
IOP Conference Series: Earth and Environmental Science, 2022 Abstract Multibeam Echosounder (MBES) utilizes acoustic waves emitted to the seafloor through a transmitter or transducer and records its reflective. The information obtained by MBES are depth data and the scattering value of the acoustic signal reflected by the object or the seabed, called backscatter.

Seabed classification using physics-based modeling and machine learning [PDF]
The Journal of the Acoustical Society of America, 2020 In this work, model-based methods are employed, along with machine learning techniques, to classify sediments in oceanic environments based on the geoacoustic properties of a two-layer seabed. Two different scenarios are investigated. First, a simple low-frequency case is set up, in which the acoustic field is modeled with normal modes.

Research on Seabed Sediment Classification Based on the MSC-Transformer and Sub-Bottom Profiler
Journal of Marine Science and Engineering, 2023 This paper proposed an MSC-Transformer model based on the Transformer’s neural network, which was applied to seabed sediment classification. The data came from about 2900 km2 of seabed area on the northern slope of the South China Sea.
