Suiting Up

In September 2014, scientists plan to explore the 2,000-year-old Antikythera shipwreck, looking for sunken statues, gold jewelry, and other ancient artifacts lost in the Agean Sea. For the mission, they'll use the Exosuit, pictured here, that allows the operator to safely descend hundreds of feet below the surface.

Marine archaeologist Theotokis Theodoulou is co-director of the Antikythera mission and the first researcher on the team certified to pilot the Exosuit. Here he prepares for a test dive.

The most famous discovery from the shipwreck is called the Antikythera mechanism. Its an ancient analog computer that tracked the movement of celestial bodies and scientists hope they will find other instruments like it.

Operators can quickly haul the Exosuit up from hundreds of feet below the surface without the risk of the diver getting decompression sickness.

The Exosuit allows the operator to reach up to 1,000 feet below the surface, and gives the operator up to 50 hours of bottom time. Phil Short, diving operations manager of the mission, conducts a test run of the Exosuit.

Phil Short was only able to pilot the Exosuit near the end of the "Return to Antikythera" mission, which lasted from Sept. 15 to Oct. 7, 2014.

Divers also explored the undersea wreckage using rebreather technology, which recycles air and allowed them to stay underwater for up to three hours at a time to dig up some artifacts, like the lagynos shown here.

This bronze spear, too big and heavy to be a functional weapon, likely belonged to a statue. It was among several tantalizing artifacts that suggest there's much more to be found at Antikythera. The team plans to return to the site in 2015 for further excavations.
