Beneath the vast ocean waters lie hundreds of thousands of preserved ancient shipwrecks, holding untold secrets of human history and trade.
Marine archaeologists recently uncovered an intact 2,100-year-old Roman merchant ship resting 150 feet deep off the coast of Sicily.
The historic Roman wreck was found carrying over 500 remarkably preserved ceramic amphora jars used to transport wine and olive oil.
Modern marine technology, including high-resolution sonar and remotely operated robotic vehicles, allows deep-sea exploration like never before.
Because deep ocean water limits oxygen exposure, submerged wooden hulls and organic artifacts remain remarkably intact for thousands of years.
Legendary shipwrecks like the Spanish galleon San José continue to yield billions in historical gold, silver, and priceless historic artifacts.
Underwater archaeological teams work globally to carefully document, protect, and preserve these fragile underwater ruins for future generations.
