Abstract

The oceans are acoustically complex and variable, with increasing human activity (e.g. shipping) and decreasing biodiversity, amplified by climate change. The long-range propagation of low-frequency waves makes them ideal to monitor far-away processes and detect individual events. I am starting my PhD using data from the Lofoten-Vesterålen (LoVe) cabled ocean observatory in Norway. The European Marine Strategy Framework Directive recommends the use of 63- and 125-Hz third-octave bands to monitor shipping noise, and my analyses span the frequency range [10 Hz – 125 Hz]. Sound Pressure Levels and third-octave bands are compared between seasons, and we can monitor shipping, detect fin whales, identify earthquakes and assess overall variations with time, from sunrise/sunset to tidal and seasonal scales.
