Understanding, using and mitigating seafloor seismological noise – BRUIT-FM

Submission summary

We propose to model, separate and use seafloor seismological noise to improve Earth and Environmental science studies. Seafloor seismological noise is generated by a combination of local, regional and global sources including waves, currents, storms, landslides, earthquakes, the polar cryosphere, marine fauna and human activities. We propose a three-pronged approach to quantify and exploit these sources: 1) Modelling of the global seafloor noise “climate”, 2) Separating/removing local sources using advanced signal processing and cutting edge instruments; and 3) Identifying and tracking sources of the seafloor “soundscape”. The project will leverage the growing library of publicly available broadband seafloor seismological data, supplemented by a few embargoed datasets that we have access to in regions of particular interest. An ERC proposal is envisioned based on the results of this study.
