Whenever pile driving is happening, loud noise carries through the surrounding water and these sounds can harm marine mammal hearing. By switching on the MMD 20 minutes prior to pile driving, and gradually increasing the volume in increments, marine mammals will be pushed to a safe zone. Pile driving operations can then begin without risk to marine wildlife.
When oil spills occur they are unexpected and can be catastrophic to the health of marine wildlife. Governments bodies and oil spill response teams should be prepared by stocking MMDs to push marine wildlife away from zones of danger towards the danger free waters.
When cables are being laid underwater, explosives are often used to cut a path through obstacles. These loud explosions carry through the water over large distances. By setting off the MMD prior to such activities marine mammals can be removed from the dangerous zone and explosives can then be detonated without risk to marine mammals hearing.
Often wild salmon, a protected species, is threatened by ever increasing numbers of seals predating on dwindling stocks. Salmon are most vulnerable as they head upstream to spawn. By installing several MMD devices across a river seals can be deterred from predating in the river. In addition, by pairing the device with a sonar trigger, the system can sit silent until the seal is detected, thus reducing unnecessary noise pollution, and increasing the effectiveness of the deterrent.
Underwater turbines currently have to be shut down whenever marine mammals are seen approaching the rotors. By installing an MMD and sonar triggering device, the turbines can keep turning and the marine mammal will trigger a noise which will push it away from the danger zone.
