My colleagues and I are pleased to announce the recent publication of our
article ‘Noise exposure from commercial shipping for the southern resident
killer whale population’ in Marine Pollution Bulletin.
Cominelli, S., Devillers, R., Yurk, H., MacGillivray, A., McWhinnie, L.,
Canessa, R., 2018. Noise exposure from commercial shipping for the southern
resident killer whale population. Marine Pollution Bulletin 136, 177–200.
The article has free access for the next 50 days, and can be downloaded by

*Abstract: *This study assesses vessel-noise exposure levels for Southern
Resident Killer Whales (SRKW) in the Salish Sea. Kernel Density Estimation
(KDE) was used to delineate SRKW summer core areas. Those areas were
combined with the output of a regional cumulative noise model describing
sound level variations generated by commercial vessels (1/3-octave-bands
from 10 Hz to 63.1 kHz). Cumulative distribution functions were used to
evaluate SRKW's noise exposure from 15 vessel categories over three zones
located within the KDE. Median cumulative noise values were used to group
categories based on the associated exposure levels. Ferries, Tugboats,
Vehicle Carriers, Recreational Vessels, Containers, and Bulkers showed high
levels of exposure (Leq−50th > 90 dB re 1 μPa) within SRKW core areas.
Management actions aiming at reducing SRKW noise exposure during the summer
should target the abovementioned categories and take into consideration the
spatial distribution of their levels of exposure, their mechanical and
their operational characteristics.
