Underwater search and recovery
Underwater search and recovery is the process of locating and recovering objects from underwater. It involves a variety of techniques, including sonar scans, diving, and remotely operated underwater vehicles (ROVs). The objects of these searches can range from sunken ships and aircraft to evidence in criminal investigations.
History[edit | edit source]
The history of underwater search and recovery dates back to ancient times. The ancient Greeks and Romans used divers to recover sunken valuables. In the modern era, the development of scuba diving equipment and underwater vehicles has greatly expanded the capabilities of underwater search and recovery.
Techniques[edit | edit source]
There are several techniques used in underwater search and recovery. Sonar is often used to locate objects on the seafloor. Divers may then be used to investigate and recover the objects. In deeper waters, remotely operated underwater vehicles (ROVs) may be used.
Sonar[edit | edit source]
Sonar is a technique that uses sound propagation to navigate, communicate with or detect objects on or under the surface of the water. It can be used to map the seafloor and locate sunken objects.
Diving[edit | edit source]
Diving is often used in underwater search and recovery. Divers can investigate objects located by sonar and recover smaller objects. There are several types of diving, including scuba diving, commercial diving, and military diving, each with its own techniques and equipment.
Remotely Operated Underwater Vehicles[edit | edit source]
Remotely operated underwater vehicles (ROVs) are unmanned vehicles that are controlled from a surface ship. They can be equipped with cameras and manipulator arms for investigating and recovering objects.
Applications[edit | edit source]
Underwater search and recovery is used in a variety of applications. It is often used in archaeology to locate and recover sunken ships and other artifacts. It is also used in criminal investigations to recover evidence. In addition, it is used in the recovery of sunken aircraft and ships.
