The findings item the agelong and often unsafe past of navigation done the Strait of Gibraltar, wherever ships moving betwixt the Atlantic and the Mediterranean person agelong converged.

A dense underwater archive of shipwrecks

A three-year task led by the University of Cádiz identified 151 archaeological sites successful the bay, including 134 shipwrecks. Researchers, moving with the University of Granada, person truthful acold documented 34 of them successful detail.

The remains span much than 2 millennia. The oldest wreck dates to the Punic epoch successful the 5th period BC.

Environmental changes are besides a concern. Rising oversea levels tin displacement sediments and exposure buried artifacts. Invasive algae are spreading crossed the seabed, covering wrecks and accelerating their decay.

Virtual entree brings shipwrecks to the public

To rise awareness, researchers person created virtual models and 360-degree videos of the sites. These are shared online and successful section museums, allowing the nationalist to research the wrecks without diving.

Visitors tin besides usage virtual world headsets to acquisition a “dryland dive.” Researchers accidental nationalist engagement is cardinal to preservation. By showing the world of these sites, they anticipation to physique enactment for protecting a unsocial grounds of maritime past astatine Gibraltar and the past Pillars of Hercules.
