Abstract
 

This study provides an indicative assessment of vessel traffic and seismic survey related noise. Vessel AIS data for the year of July 2014 to June 2015 was used to determine density and speed grids by vessel category. JASCO’s cumulative vessel noise model was used to model the sound from 15 vessel categories and two marine seismic surveys during representative summer and winter months in 1-minute time steps. Results are presented as maps, animations and plots of sound levels at static locations.
