June Jones Reef is a marine dive site in Portugal featuring the remains of a 50ft steel boat. The vessel has been significantly impacted by storms, resulting in a widely dispersed debris field across the seabed. Divers can explore these scattered mounds of wreckage, which contain various structural elements. Due to the nature of the site, careful navigation is required to locate the dispersed sections. Water temperatures at this location are consistently cold, recorded at approximately -2C throughout the year. This site is suited for divers comfortable with wreck exploration in challenging, low-temperature conditions.

Butler Barge is a 200-foot vessel intentionally sunk to function as an artificial reef. The wreck rests at a depth of 78 feet. Divers can access the site via both shore and boat entries. Due to the extreme water temperatures, which remain consistently around -2C throughout the year, this site requires specialised thermal protection and experience in cold-water diving environments. The structure of the barge provides a distinct underwater topography for exploration, though divers should be prepared for the challenging thermal conditions present at this location.

Tug Boat Janet is an artificial reef located 24 kilometres offshore from Panama City Beach. This wreck sits at depths between 20 and 30 metres, requiring boat access and intermediate diving skills. Divers encounter mild currents and visibility ranging from 10 to 30 metres. A sharp thermocline is often present, causing significant temperature drops below the surface layer. Hazards include entanglement risks within the wreck structure, deep water, and the presence of lionfish. Species recorded around this area include drum, croaker, slippery dick, crabs, bream, hermit crabs, sea hares, bluebottles, snails, and mullet. Divers should monitor depth gauges closely and prepare for variable conditions.

The Phoenix Barge, also known as the Lost Barge, is an artificial reef and wreck site located in Spain.
