After spending the last month at the historic wreck site, the <a href="http://www.whoi.edu/news-release/antikythera-finds" target="_blank">Woods Hole Oceanographic Institute</a> (WHOI) announced that an international team of archaeologists had recovered new items from the Antikythera wreck. Pictured, Greek technical diver Alexandros Sotiriou discovers an intact "lagynos" ceramic table jug and a bronze rigging ring. The new items have indicated the wreck site is much bigger than previously believed, scattered across 300 meters of seafloor.

WHOI diving safety officer Edward O'Brien "spacewalks" in the next-gen atmospheric "Exosuit," during the 2014 Return to Antikythera project, which ran from September 15 to October 7. The divers are planning to return to the Antikythera next year to continue excavating the site following a successful first season.

In 1900, Greek sponge divers inadvertently stumbled upon an incredible ancient shipwreck off the coast of Antikythera. More intriguing were the heavily corroded bronze fragments -- 82 in total, with the largest pictured -- brought to the surface in 1902. The find would stun the world when it was revealed to be a mechanical computer from the 1st century BC.

At first, the Antikythera Mechanism, as it became known, confounded archaeologists who were unsure if it was an astrolabe or an ancient astronomical clock. Today, it is widely believed the mechanism was a complex computer tracking the astronomical calendar and lunar movements, with its manufacture dated to around 100 BC. Radiographic image analysis on the mechanism revealed 30 intricate gear wheels.

A reconstruction of the device now sits at the Archaeological Museum in Athens. Built out of a thin bronze sheet, the mechanism has the first known set of scientific dials and scales. Surrounded by Greek inscriptions, the large upper dial follows the Metonic cycle -- a period of 19 years in which there are 235 lunations. Useful for regulating calendars, there was also a four-year dial for monitoring when the well-loved Panhellenic games -- including the ancient Olympics -- should take place.

"The Antikythera Mechanism is just mind blowing. It's maybe the most important, certainly most surprising, artifact recovered from an archaeology site anywhere," said expedition co-director Brendan Foley. "Our question is: if this ship is carrying this kind of stuff, what else is still down there? You can't even guess. The Antikythera Mechanism had no precedence. Could there be other things of that sort of culture, and technological and scientific significance still down there?"

Archaeologists are also translating findings from the reports from 1900 and 1901 operations from Ancient Greek hoping to reveal more clues to the initial find. Foley said one of the journals revealed there were two main areas where it was reported marble and bronze lay, so technical divers will be carrying metal detectors to aid their search. He added: "If we get a really big metal detection hit in one localized area then obviously that would be a place to test trench and see what's down there. Maybe there's another mechanism ..."
