The Australia is a wreck site located 4828m off the coast of Cape Hatteras, United States. This advanced dive site sits at depths ranging from 27 to 33 metres, with an average depth of 30 metres. Divers access the wreck by boat, with guided tours and air fills available through local charters. Conditions are variable, with visibility between 10 and 30 metres and water temperatures fluctuating from 17C to 24C. Divers should be prepared for potential thermoclines, cold water, and strong currents. Due to the depth and environmental factors, this site requires advanced certification and careful monitoring of dive profiles.

The Empire Gem is a wreck located off Cape Hatteras, United States, resting at depths between 34 and 49 metres. This site is strictly for advanced divers due to the significant depth, strong currents, and overhead environments created by the wreck structure. Visibility is variable, ranging from 8 to 30 metres. Water temperatures fluctuate between 17 and 23 degrees Celsius, with thermoclines often present at depth. Boat access is required to reach this site, which lies approximately 19 kilometres offshore. Divers must manage gas and buoyancy carefully while navigating the wreck, and should consult tide tables to plan for slack water windows.

AR-225 is an artificial reef located 11.3 kilometres offshore from Cape Hatteras. The site sits at a consistent depth of 21 metres and is accessible only by boat. Divers encounter mild currents, though surge and swell are common variables that require careful monitoring of local offshore forecasts. Visibility typically ranges between 10 and 20 metres. The site is suitable for intermediate divers, with a typical dive duration of 40 minutes. Water temperatures fluctuate between 15 and 24 degrees Celsius throughout the year, necessitating appropriate thermal protection. The structure supports a variety of reef fish and invertebrates typical of the region.

AR-220 is an artificial reef located 8519 metres off the coast of Cape Hatteras. The site features depths ranging from 5 to 20 metres, with an average depth of 19 metres. Visibility is consistently 10 metres. Access is by boat only, and the site is suited for intermediate divers. Conditions include mild currents, though strong currents, surge, and swell can occur. Divers should monitor local conditions and tide tables, aiming for slack water to manage current shifts. Sharks are known to frequent the area, requiring vigilance throughout the dive. Typical dive duration is 40 minutes.

Mr. J.C. Reef is an artificial reef and wreck site located 6482 metres off the coast of Cape Hatteras. The site sits at a consistent depth of 22 metres and is accessible only by boat. Divers encounter variable visibility ranging from 5 to 20 metres, influenced by the confluence of the Gulf Stream and the Labrador Current. The site features an overhead environment and potential entanglement risks, requiring appropriate certification and caution. Marine life at this habitat includes various reef fish and invertebrates. Divers should monitor for boat traffic, surge, and lionfish while maintaining neutral buoyancy to avoid contact with the structure.

The U-701 is a German Type VIIC U-boat resting upright on a sandy bottom at a depth of 37 metres. Located 37 kilometres offshore, this site requires boat access and is reserved for advanced divers due to the depth and strong currents. Visibility is highly variable, ranging from 3 to 30 metres, and thermoclines may occur. Divers should plan for a 30-minute bottom time and coordinate descents with the turn of the current. The hull serves as an artificial reef, supporting a variety of reef fish and invertebrates. Given the offshore location and potential for shifting conditions, divers must carry a surface marker buoy and manage gas supplies carefully.

The Catherine M. Monahan is an artificial reef wreck located 22.5 kilometres off the coast of Cape Hatteras. Resting at depths between 29 and 32 metres, this site is reserved for advanced divers. Visibility ranges from 10 to 30 metres, allowing for clear views of the wreck structure. Divers typically experience mild currents, though the significant depth requires careful management of decompression stops. Access is strictly by boat, and divers must remain vigilant regarding boat traffic during ascent. A redundant buoyancy device is recommended for this profile, which averages 35 minutes in duration.

The Keshena is a shipwreck located off Cape Hatteras, United States, offering a varied profile for intermediate divers. The site spans depths from 4 to 27 metres, with the deeper hull sections requiring careful monitoring for nitrogen narcosis. Visibility typically ranges between 10 and 21 metres. Access is exclusively by boat, and while currents are generally mild, they can strengthen, necessitating local checks before diving. Divers should exercise caution regarding the presence of lionfish within the wreck's cavities and overhangs. Given the depth range, divers should manage bottom time effectively to ensure a safe profile across the structure.
