In 1912, the Titanic sank colliding by an iceberg as a virgin voyage from Southampton to New York. 1517 people died because of this tragedy. It was later turned into a film by James Cameron and became one of the smash hit movies around the world, and what was used to shoot was an unmanned subsea robot ROV (Remotely Operated Vehicle).

The sunk Titanic cannot be preserved as it was eternally due to decay. In August 2019, Triton Submarine surveyed the Titanic in 4K image (underwater) video. In recent years, it has been increasing in the importance of underwater archaeological surveys with using ROV worldwide.

Tokyo submarine canyon, is located at Sagami trough in the vicinity of Tokyo and Sagami Bay, where the Philippine Sea Plate is subducting beneath the North American Plate. Geological and environmental seafloor surveys were conducted with Boxfish ROV (Boxfish Research) and Boxfish 360 camera at the depth of 300 meters on February in 2020. The surveys were technically very challenging because of the rapid current in this site. In this presentation, we will show the example of underwater archaeological survey with Boxfish ROV and Boxfish 360 camera.

It is considered that there are a lot of underwater archaeological sites around Japan due to the rapid current and earthquakes. However, there have not been many surveys with using ROV and the archeological sites are not well comprehended. It is expected that the underwater archaeological surveys with using ROV and underwater 360 spherical cameras will be used more practically in the future.
