Acoustic data optimisation for seabed mapping with visual and computational data mining
… will examine the complexity of the de facto seabed mapping technique by exploring and analysing acoustic data with a combination of data mining and visual analytic methods. First we test the redundancy issues in multibeam echosounder (MBES) data by using the component plane visualisation of a …

The effectiveness of Autonomous Underwater Vehicles (AUVs) for mapping and monitoring the seabed – a novel toolkit for marine management
… usual method of obtaining this data is through seabed mapping and sampling. Mapping is relatively widespread, ranging from historically simple tools such as plumb-lining, through to modern and novel technology with remote sensing capabilities. Sampling using imagery and grabs is conducted to …

Characterization of Natural and Anthropogenic Seabed Features in the Southwestern Baltic Sea
… from human activities that can disturb the seabed and may threaten the proper functioning of marine ecosystems. A sustainable balance between human uses and seabed integrity requires knowledge of the seabed's physical characteristics, benthic habitat distribution, and the extent of human …

The application of machine learning and 3D photogrammetry for cold-water coral habitat classification in the NE Atlantic
… This thesis explores methods that can advance seabed mapping to further understand cold-water coral reef habitat features in the deep sea considering their natural, three-dimensional structure and posed data analysis demands given the current technologies. The key aims of the research were to: …

Quantitative Comparison of Benthic Habitat Maps Derived From Multibeam Echosounder Backscatter Data
… achieve the identification, classification and mapping of seabed types and of benthic habitats. These approaches, commonly grouped under the denominations of Benthic Habitat Mapping or Acoustic Seabed Classification, exploit the latest scientific and engineering advancements for the exploration …
