Abstract:
The laboratory carries out fundamental and applied research on the characterisation of marine/aquatic environments and ecosystems primarily by remote, active and passive acoustic sensing, but also by optical sensing. Since its creation, the lab has been participating in international interdisciplinary projects, primarily on global environmental issues, and has been conducting field experiments at sea on a regular basis in different parts of the world.

Current research includes the following topics:
- Use of acoustics to improve our understanding of pelagic and benthic ecosystems;
- Development of acoustic systems for the characterisation of surface sediment and subsurface layers;
- Non-invasive acoustic investigation of fluid mud dynamics and associated processes in estuarine and coastal environments (e.g. Amazon River mouth);
- Design and field testing of submersible digital holographic microscopy for in situ observation of plankton and particles in fisheries surveys (West Africa);
- Integrated acoustic monitoring of marine habitats to assess primary production and biodiversity (seagrass meadows off Tyrrhenian Sea islands; kelp forests off Southeast Australia);
- Passive acoustic sensing of sediment transport in lagoons and coastal environments (e.g. Venice, North Sea beach);
- Acoustic exploration of submarine archaeological sites and geoacoustic characterisation of cultural layers;
- Feature-based acoustic tomography of shelf and coastal ocean processes (Ushant tidal front, Northwest France; deep thermal front, Southeast Brazil);
- Comprehensive assessment of marine sediments by combining hydrographic surveying and geoacoustic inversion (e.g. Caribbean, Mediterranean).

As part of research projects, the group develops methods and algorithms to solve a variety of data assimilation and inverse problems, pioneering the application of optimal control theory and Bayes statistics. Modelling acoustic propagation and scattering to support offshore experiments including the development of approaches for complex media and multiphase materials are core activities of the lab. For some materials, e.g. flint and biological tissue, ultrasonic measurement techniques are developed to determine intrinsic acoustic properties on samples from expeditions. Sedimentological and lithostratigraphic analyses of short sediment cores are carried out in partnership with STEP, ULB and foreign labs. The lab has a well-developed expertice in applying advanced signal processing to sound propagation measurement, soundscape recording, e.g. ship-radiated noise and biological sound production, raw backscatter data from scientific single or multibeam echosounders. Through extensive offshore experimentation, the lab has consolidated expertise in the development of acoustic and oceanographic sensor packages specifically conceived to fulfill efficiently each project’s scientific objectives. The staff and partners of the lab are specialised in acoustics, geophysics, marine biology and ecology, applied mathematics, signal and image processing and ocean engineering.
