ECHO Program | Vessel Noise Correlations Studies
January 2021 — British Columbia, Canada
Client: Port of Vancouver
Phase 2 Report (January 2021)
Phase 1 Report (May 2020)
A two-part study for the Vancouver Fraser Port Authority ECHO Program analyzing the statistical correlations between vessel design characteristics and underwater radiated noise levels, to determine design or operational characteristics that may be correlated with louder or quieter sound levels.
Phase 1 of the study analyzed data collected from Haro Strait and the Strait of Georgia between 2015-2018. Phase 2 expanded to include: data collected by JASCO’s Boundary Pass Underwater Listening Station from 2018-2020; more detailed ship characteristics for a subset of vessels; and analysis of the variability in underwater radiated noise levels for repeat passes of the same ship.
A collaboration with ERM and Acentech.
