Jo Marchant has written another piece for the Guardian (confusingly, with the same title as a previous piece) detailing a bit more what they hope to find … in medias res:
[...] For centuries Antikythera was in a busy shipping lane, but surprisingly its treacherous underwater cliffs and reefs are not littered with sunken ships (perhaps those ancient navigators were more skilled than we thought). And there are no obvious signs of a wreck at the site supposedly excavated by Cousteau, suggesting that he recovered all of the visible items there – or that he planted some of his finds for the cameras.
But 200 metres away, the divers found artefacts spread across the rocky sea floor, on a steep slope between 35 and 60 metres deep.
The largest item recovered was a huge lead anchor stock. It was lying on a semicircular object that might be a scupper pipe, used to drain water from the ship’s deck. If so, the ship may have gone down as she was sailing with the anchor stowed. The team also raised an intact storage jar (amphora), which matches those previously recovered from the wreck. DNA tests may reveal its original contents.
Most intriguing are dozens of irregular spherical objects sprinkled across the wreck site. They look like rocks but contain flecks of green, suggesting small bronze fragments, corroded and encrusted in sediment after thousands of years in the sea. This is just what the Antikythera mechanism looked like when it was discovered. Then again, they could be collections of ship’s nails.
Because the artefacts the team found are a short distance from the site investigated by Cousteau, it’s possible that they belong to a second ship from around the same date as the original wreck, perhaps part of the same fleet. But Foley thinks it more likely that all of the remains come from one vessel that broke up as it sank.
To confirm this, he hopes to revisit the site later this year. He wants to use metal detectors to map the distribution of metal and ceramic objects buried beneath the surface, as well as dig a few test trenches. “I’m intensely curious about what’s in the sediments,” he says. [...].
