Tappan Zee Hudson River Crossing Project: Final Environmental Impact Statement
July 2012 — New York, United States
Client: AECOM
Appendix F-4A – Hydroacoustic Noise Modeling
Appendix F-4B – Hydroacoustic Noise Modeling – Appendices
Appendix F-5A – Underwater Acoustic Monitoring of Pile Installation Demonstration Project
Modelling and monitoring of sounds from vibratory and impact pile driving in support of New York State Thruway Authority’s Environmental Impact Statement for the Tappan Zee Bridge replacement project, which received approval in March 2013. During the initial demonstration project, JASCO evaluated the effectiveness of five noise attenuation systems in lessening the impact of pile driving noise on Atlantic sturgeon, a species in recovery in the Hudson River.
White Rose Extension Project
June 2012 — Newfoundland, Canada
Client: Husky Energy
Underwater Sound Propagation Assessment
An underwater sound propagation assessment to estimate distances to sound level thresholds around potential acoustic sources resulting from various phases of the White Rose Extension Project: construction of concrete gravity structure (CGS) at Argentia involving dredging and blasting; transportation of the CGS to the field site at Grand Banks involving dredging, drilling, support vessel, and helicopter operations; and drilling from a wellhead platform or subsea drill centre.
