"Over the weekend, the Australian government revealed that last Tuesday 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 recognised 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 the Australian government, who labelled
the incident “unsafe and unprofessional”. But what exactly is a sonar pulse,
and what kinds of injuries can sonar cause to divers?"
