What is a Sonar Pulse and How Can it Injure Humans Under Water?
Last month, the Australian government revealed that its navy divers had sustained “minor injuries”, likely due to sonar pulses from a Chinese navy vessel.The divers had been clearing fishing nets from the propellers of HMAS Toowoomba while in international waters off the coast of Japan. According to a statement from deputy prime minister Richard Marles, despite HMAS Toowoomba communicating with internationally recognized signals, the Chinese vessel approached the Australian ship and turned on its sonar, forcing the Australian divers to exit the water.The incident prompted a response from

We’ve Discovered Why Some Whales Stop Feeding in Response to the Sound of Sonar
In September 2002, a number of beaked whales were stranded and killed in the Canary Islands during a NATO naval exercise. It was the first time we started to get a real understanding of the negative effects of sonar sounds on cetaceans, which includes whales, dolphins and porpoises.But why did the noise of sonar seem to affect beaked whales in particular, rather than other species of cetacean?In our new research, we’ve discovered that the response of each species to predators could explain why some whales and dolphins are more sensitive to this human-made noise.It was back in the early 2000s

Tech File: Sonar Equipment Critical to Search and Recovery
According to the CDC, 3,960 fatal unintentional drownings, including boating-related drownings, occurred in 2020. To locate the missing persons and provide closure to families, it takes dive teams time to assemble, gather their equipment, and begin searching sometimes vast bodies of water. Searching via divers is not only a long process, but it adds a considerable level of risk to an already dangerous assignment. One way to avoid that elevated risk is to use modern technology to help aid in the search. Side Scan Sonar technology allows a search and recovery team to scan local waterways quickly
