Paper Summary
To obtain a permit for any seismic survey it is often necessary to demonstrate the potential impact of seismic sources on any marine mammals present in the survey area. This is called environmental modeling, and is done by estimating the sound levels emitted from the source as well as the corresponding received levels; the latter being what any marine animal present in the area would hear. I consider two different survey areas and the challenges associated with them. A different approach was used for each of them in order to assess the impact on marine fauna in the respective survey areas.
