In order to obtain oil and gas from the ocean floor, industries first explore the territory with seismic airguns? These airguns create some of the loudest humanmade sounds in the oceans—and can you guess what else happens? They do not just fire the airguns once; the average seismic survey consists of 7000 shots over 24 hours! How does the marine life cope with such noise?
Davidsen et al (2019) investigated just that. They wondered how cod and saithe— two culturally and economically important species—respond to the sound of seismic airguns. What does this tell us? Well at this point, it remains unknown just how bad these seismic surveys are for the marine ecosystem as a whole, but it seems that, at least for cod and saithe, exposure to airgun sounds for a 3-day period is unlikely to have long-term consequences
Summary
Users may download and print one copy of any publication from the public portal for the purpose of private study or research. The sounds of airguns are equivalent to [140–180] dB on land. They wondered how cod and saithe— two culturally and economically important species—respond to the sound of seismic airguns.
