Marine divers are responsible for a variety of tasks, including conducting underwater inspections, repairs, and maintenance on ships, pipelines, and other structures. They may also engage in underwater welding, salvage operations, and scientific research, such as marine biology studies or environmental monitoring. Safety is paramount, so divers must adhere to strict protocols and use specialized equipment to ensure their well-being while working in challenging underwater environments. Additionally, they often document their findings and report back to their teams or clients.
Being completely underwater is referred to as being submerged.
The wavelength of sonar waves can vary depending on the frequency of the sound waves being emitted. In general, the wavelength of sonar used in underwater applications ranges from a few centimeters to several meters. The selection of the frequency and corresponding wavelength is based on the specific requirements of the sonar system and the properties of the underwater environment being explored.
Commercial divers do all sorts of things from underwater welding, to salvage and recovery, to security and police work. check out the attached link for more information (click the "related links" link).

If people are diving when a tsunami hits the ocean, they may not immediately feel the effects due to the depth and distance underwater. However, as the wave approaches shore, it can create strong currents that can be dangerous for divers as they resurface. It is important for divers to stay calm and follow safety protocols to avoid being caught in dangerous situations.
