Researchers person identified 150 underwater archaeological sites — the bulk of which are shipwrecks, according to The Guardian.

The wrecks span centuries, from arsenic aboriginal arsenic the 5th period B.C. to World War II-era vessels.

The vessels see 23 Roman ships, 4 medieval ships, and the motor and propeller of a level from the 1930s, according to The Guardian.

The findings were "not a accidental discovery," said Felipe Cerezo Andreo, a lecturer successful archaeology astatine the University of Cádiz — and the find took years successful the making.

The archaeologist told Fox News Digital successful translated comments that his team's probe has dramatically expanded what was antecedently known astir the area.

"Before starting Project Herakles successful 2019, lone 4 underwater sites were known successful the area; contiguous we person accusation connected much than 150 documented sites successful conscionable 3 years of work," helium said.

"They tin present beryllium studied, protected and shared."

Researchers combined humanities probe with precocious exertion to locate, representation and survey the wrecks.

"We began by analyzing humanities archives, museums and interviewing the section assemblage of fishermen and divers, who cognize the seabed amended than anyone," Andreo recalled.

Archaeologists past utilized precocious marine scanning exertion to representation the seafloor and find buried shipwrecks, including magnetometers to "detect metallic anomalies."

Andreo said astir of the recorded shipwrecks are from the 18th to 20th centuries — but older Phoenician, Punic and Roman vessels are besides buried successful the sands.

"That is why, successful Herakles, we prioritize non-intrusive documentation, [such as] photogrammetry and 3D models, to grounds everything earlier it disappears, pursuing UNESCO principles of successful situ conservation," helium said.

The archaeologist stressed that the shipwrecks are inactive a surviving taste resource, and that his squad is "working to marque this practice accessible to everyone."

"We privation nine to consciousness that these shipwrecks are their 'museums beneath the sea.'"

The squad is readying an underwater parkland and VR experiences, truthful that radical tin research the shipwrecks without risking further harm to the sites, Andreo added.
