Santos Basin, the key oil province in Brazil, has been object of extensive monitoring project – PMPAS-BS. This work presents modelling framework developed in this project, along with first results. Noise radiated by shipping and waves, in particular 63 Hz to 125 Hz band, were computed with use of normal modes model to general monthly/annual SPL maps with 1/6 degree resolution. Results show agreement between model and observations. Accuracy suggests modelling approach crucial for underwater noise characterization.
