The sonar being used in the test was an experimental research and development sonar, which was considerably smaller and less powerful than an operational sonar on board a deployed naval vessel. Dr Frantzis believed that wide distribution of the stranded whales indicated that the cause has a large synchronous spatial extent and a sudden onset.
Divers may carry a yellow flag or surface marker buoy to attract attention. Divers may carry a personal submersible EPIRB or vhf radio. Divers may carry a signalling mirror and/or sound signalling device. Diving from unattended boats only when a safe shore exit is feasible. Inability to return to shore or to exit the water.
Examples of diver-detecting active sonar systems are: AN/WQX-2 – Diver detection sonar used in defense against underwater incursions; Cerberus (sonar) – Diver detection device; Underwater Port Security System – Defense against hostile swimmer incursions; Trained animals Trained dolphins and sea lions can find submerged divers.
Australia on Saturday accused the Chinese navy of likely causing minor injuries to Australian naval divers by operating its sonar while they were trying to clear fishing nets from their ship's ...
Analysts say sonar pulses can cause extensive soft tissue damage to divers at close range. Australia says the Toowoomba notified the Ningbo that diving operations were underway and asked the ...
The Integrated Anti-Swimmer System is a United States Coast Guard underwater anti-diver ultrasound weapons system. IAS includes:- SM2000 (Underwater Surveillance System), a search sonar made by Kongsberg Maritime. An underwater warning loudspeaker. An underwater shockwave emitter that can force divers to surface, or stun or kill them. The US ...
"Soon after, it was detected operating its hull-mounted sonar in a manner that posed a risk to the safety of the Australian divers who were forced to exit the water." The conduct was "unsafe and ...
As depth increases, the mental impairment may become hazardous. Divers can learn to cope with some of the effects of narcosis, but it is impossible to develop a tolerance. Narcosis affects all divers breathing gas mixtures containing nitrogen, although susceptibility varies widely from dive to dive, and between individuals.
