What is it about?
Inter-pulse noise field during a marine seismic survey in the Arctic exceed ambient noise level if there were no airgun firing. This increase is due to reverberation of airgun pulses in the marine environment.

Why is it important?
The results suggest that marine mammal could experience acoustic masking even though they may not exhibit behavioral disturbances in the vicinity of a marine seismic survey.
Perspectives
There have not been many studies done to quantify overall noise levels during a seismic survey, especially in quantifying inter-pulse reverberant field.
