Sound Pressure Level time series at OBSEA seabed observatory (30min averages)

Ocean sound

Sound Pressure Level (SPL) time series derived from passive acoustic recordings at the OBSEA seabed observatory. Data are computed following Marine Strategy Framework Directive (MSFD) guidelines. SPL values are calculated in 1/3-octave bands (63 Hz, 125 Hz and 2 kHz) using 10-second time windows. Data is averaged every 30 minutes
