Modelling Arctic ambient noise in the 2 - 200 Hz band / by M.V. Greening and P. Zakarauskas.: DR52-11/11-1993E-PDF

"Short-term Arctic ambient noise spectra over the frequency band 2 - 200 Hz are presented along with a two-component noise model capable of reproducing these spectra. The model is based on the measured source spectrum and the spatial, temporal and source level distribution of both active pressure ridging and ice cracking. Modelled ambient noise levels are determined by summing the input energy of the distributions of ice cracking and pressure ridging events and correcting for the propagation loss. Both modelled and measured spectra show that ice cracking may dominate the spring-time ambient noise to frequencies as low as 40 Hz."--abstract (page 2).
