Definitions

Cetacean
a whale, dolphin or porpoise.
Critical habitat
the habitat that is necessary for the survival or recovery of a listed wildlife species and that is identified as the species' critical habitat in the recovery strategy or in an action plan for the species.
Marine Mammal Observer
an individual trained to identity different species of marine mammals and turtles that may reasonably be expected to be present in the area where the seismic survey will take place.
Marine mammals
all cetaceans and pinnipeds.
Passive Acoustic Monitoring
a technology that may be used to detect the subsea presence of vocalizing cetaceans.
Pinniped
a seal, sea lion or walrus.
Ramp-up
the gradual increase in emitted sound levels from a seismic air source array by systematically turning on the full complement of an array’s air sources over a period of time.
Seismic air source
an air source that is used to generate acoustic waves in a seismic survey.
Seismic air source array(s)
one or a series of devices designed to release compressed air into the water column in order to create an acoustical energy pulse to penetrate the seafloor.
Seismic survey
a geophysical operation that uses a seismic air source to generate acoustic waves that propagate through the earth, are reflected from or refracted along subsurface layers of the earth, and are subsequently recorded.
“Statement"
the Statement of Canadian Practice for the Mitigation of Seismic Sound in the Marine Environment.
Whale
a cetacean that is not a dolphin or porpoise.
