Statement of Canadian Practice with respect to the Mitigation of Seismic Sound in the Marine Environment
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.
