Jean-Yves ROYER

Université de Brest

JYR is a senior scientist at CNRS working in Brest, with a background in marine geophysics. For two decades, he has been developing and maintaining large networks of autonomous hydrophones, continuously recording the open-ocean low-frequency soundscape (0-120Hz). Of interest in this band-width, are the sounds generated by the low-level seismic activity and volcanic activity associated with seafloor spreading ridges, the sounds produced by large baleen whales, which help detecting their seasonal presence and migration patterns, and other sounds such as icequakes from the high latitudes, man-made sounds (ship trafic, seismic exploration), or ultra-low frequency noise related to the sea-state. In the last decade, he has also been interested in marine geodesy for monitoring displacements of the seafloor.
