SEUSS, innovative modelling to safeguard marine ecosystems worldwide.

Our oceans are becoming increasingly noisy. Between 2014 and 2019, underwater noise levels in European waters more than doubled, largely due to the shipping industry. Climate change is compounding the problem, with stormier seas generating more wave-related noise. This growing acoustic pollution threatens marine species that rely on sound for communication, navigation, and survival. Current modelling approaches often struggle to distinguish between natural and man-made noise sources, making it difficult to accurately assess the potential impact of new marine infrastructure developments such as ports, wind farms, dredging, and seabed mining operations.

SEUSS addresses these challenges by introducing satellite-enabled enhancements to underwater noise modelling. It uses Automatic Identification System, (AIS) data to map ship positions and generate accurate, localised background noise profiles, while satellite weather observations help infer noise from sea conditions. These data streams are integrated with our proven underwater noise models to produce detailed spatio-temporal noise fields that feed into assessments of potential ecological impacts. The results are delivered through an intuitive interface featuring charts, tables, and maps, giving regulators and contractors the tools they need to make informed decisions and implement effective mitigation strategies.

The animation above shows simulation results from the SEUSS system using AIS data of moving vessels in Falmouth Bay (UK).

By improving the accuracy of underwater noise assessments, SEUSS helps ensure that marine developments meet environmental standards and minimise harm to marine life. This innovation supports sustainable growth in offshore industries while safeguarding biodiversity. With global accessibility, SEUSS empowers stakeholders worldwide to better understand and manage underwater noise, contributing to healthier oceans and more responsible marine development.
