The monumental coral, of the species Pavona clavus, was discovered by researchers of the National Geographic Pristine Seas project during an expedition to the remote Three Sisters Islands in the southwestern Pacific Ocean. Initially mistaken for a shipwreck or large rock due to its size, the structure was confirmed to be a single coral colony, surpassing previous records for individual corals.

The Research Vessel R/V Petrel’s autonomous underwater vehicle (AUV) first identified the ship in its side scan sonar on March 17. Upon analysis of the sonar data, the Petrel crew deployed its remotely operated underwater vehicle (ROV) on March 18 to verify the wreckage through its video capabilities.

On 14 January 2019, the wreck of USS Wasp was located by the research vessel Petrel. The carrier sits upright in 4,345 meters (14,255 feet) of water, though parts of the hull appear to have split.
