2013 afs sustained noise effects_christa woodley
DESCRIPTION
In recent years, the potential impact of underwater sounds associated with drilling and dredging operations are under scrutiny by regulatory agencies. Underwater noise generated from petroleum industry seismic surveys and construction activities such as pile-driving have been identified sublethal and lethal to fish and marine mammals. The NMFS is currently developing guidelines for determining sound pressure level thresholds for fishes and marine mammals. Most scientific literature pertaining underwater sound effects on fishes have largely resulted from pile driving operations. Drilling sound ranges from 100 to 220 dB re 1 µPa up to distance of 800 m. To better understand the effects of underwater sound from hydraulic drilling operations, a long-term monitor approach is needed using passive acoustics (PAM) combined with the FIT (Fish Index of Trauma) model. This presentation focuses on the development of this model system with a case study of fish injury from underwater noise. The critical issues addressed are generated sounds relative to ambient noise, and how to assess sound effects on fish.TRANSCRIPT

Sustained Noise Knowledge
Drilling/fracking noise can be +55 dB at setback distance 1067m
The compressor stations are constant and semi-permanent sound sources
No current estimates dB or spectral content
Current regulations are based on single source estimates
Fail to sum the various processes together
Few regulations on proximity to neighboring water bodies
No current monitoring of noise effects on neighboring water bodies
