Seismic testing for offshore drilling is far from harmless:
The National Science Foundation safely conducted a 2D seismic survey off the coast of North Carolina last fall. Interestingly, this study did not receive the attention that the proposed studies have generated, despite the fact that they used the same technology that is proposed for oil and gas seismic data collection. The N.C. Divisions of Coastal Management and Marine Fisheries did not receive any reports of disturbances or injury to marine wildlife and are unaware of any adverse impacts resulting from those surveying activities.
That is consistent with observations made by the National Oceanic and Atmospheric Administration in May 2015, which found no evidence that serious injury, death or stranding by marine mammals can occur from exposure to air gun pulses, even in the case of large air gun arrays. Sadly, some political groups masquerading as environmental organizations have chosen to ignore these realities.
Bolding mine. Not only is that an asinine statement, it's ironic as hell coming from a political appointee who has attacked Roy Cooper for not opposing the EPA's Clean Power Plan. Van der Vaart is proving to be even more of a demagogue than his predecessor, and that's saying a helluva lot. I don't need to tell you that, but I do need to throw some actual science into the discussion. Due to their environment, ocean fauna rely on sound more than any other sense to survive and procreate:
