Ten metres (33 feet) under the sunlit blue sea off the island's south coast, divers slowly swim around the "Lef 1" shipwreck, filming as they go.
The 16-metre vessel, surrounded by shoals of small black damselfish, is one of five popular sites in the project which aims to map them using photos and videos to build up digital 3D models of the sites.
"We're taking quite a lot of info through photography of the seabed and then we're stitching it together through programming on the computer to create a video that gives you a 360 (degree) tour," said visual designer Marios Constantinides.
Constantinides says the tours and mapping of dive routes will allow divers "to understand the potential dangers or points of reference".
The tours will be available on an online platform by the end of the year in the project called Larnaca Virtual Underwater Routes.
It is a joint venture between the Cyprus Maritime and Marine Institution and the Larnaca Tourism Board.
The sites include two natural reefs and three wrecks, including the well-known Zenobia, an iron-and-steel colossus that sank in 1980 to its final resting place 40 metres (130 feet) down, just a 10-minute boat ride from the coastal resort of Larnaca.
While authorities are hoping the mapping project will stimulate tourism, it also aims to promote environmental awareness.
Artificial reefs, such as the sunken boats, can boost the biodiversity of nearby natural reefs by creating new havens for oceanic fauna.
Mapping the sites makes them "more accessible to tourists and the general public," Constantinides says.
