The BRUIT-FM Seafloor Noise Reduction Challenge

The French ANR BRUIT-FM project studies seafloor noise from 0.001 to 100 Hz, in order to separate the different seismological, environmental, biological and anthropomorphic signals therein.  One aspect of the project is the reduction of environmental noise from 0.001 to 0.1 Hz in order to better study seismological signals therein, such as earth’s normal modes and ambient noise, earthquake surface waves and seafloor compliance. We have already developed and published some tools for reducing noise (see http://www.bruit-fm.org/), but would like to learn about and test other tools, perhaps coming from very different fields.  The BRUIT-FM Seafloor Noise Reduction Challenge provides sample datasets to any scientist, shows them the best we have been able to remove the noise and to extract signals of interest, and challenges them to apply their own tools to the data and send us their results.  We will compile the results and write a community paper including any of the participants who shares their codes/methodologies.
