The study of geophysical properties of shallow marine environments is critical for characterising the subsurface in offshore sites for both the oil and gas industry and also the geotechnical characterisation of the soil for the construction of sites like the ones for off shore wind turbines. Due to the complexity of these environments, like heterogeneity of sediments and complex water-sand interactions, conventional seismic geophysical methods may be challenging, time consuming and costly. This thesis focuses on the importance of studying Scholte waves propagation along the seabed in order to successfully characterise shallow marine sediments and further improve the resolution of subsurface models in coastal environments.
