Bay du Nord Development Project Environmental Impact Assessment

View Report

July 2020 — Newfoundland, Canada

Client: Equinor Canada

Appendix D – Underwater Sound Modelling of Seismic Survey and Development Activities Off-shore Newfoundland

Appendix L – Marine Mammals and Sound Sources in the Flemish Pass: Analysis from 2014 to 2017 Acoustic Recordings

Modelling and analysis studies for Equinor as part of their EIA for the proposed Bay du Nord Development Project, a floating offshore oil and gas production facility, 500 km east of Newfoundland. Modelled sources include an airgun array for seismic surveys, sub-bottom profiler and multibeam sonar for geohazard surveys, drillship, and the floating production, storage, and offloading facility. The analysis of four summers of acoustic recordings characterized the baseline soundscape, the presence of marine mammals, and the effects on the soundscape of Equinor’s 2014–2016 drilling program.
