According to an analysis from the Russian Academy of Sciences in Syktyvkar, the largest pieces found are mostly copper, while the smallest are made of tungsten and molybdenum. If Cousteau and his team made sprints to the Antikythera, the WHOI exploration is set to be more of a marathon. Listen - 01:44. Is our current ground level higher than it was in the past? Was it the Svärdet they had found? Potentially, more of the bronze statues recovered on previous trips--hands, feet and other fragments have been found and are on display in the National Museum in Athens--could be identified through the metal heat map. As well as images, the technology gathers the precise position of artefacts and other elements, so no need to pin out grids on the site either. The world’s oldest computer predates Bill Gates only by about 2,000 years. "Putting humans in the water is always the option of last resort because we have to eat, we have to poop, we get tired and we're really not that efficient underwater. The team is using an autonomous underwater vehicle equipped with stereo cameras. The detailed way the way the wreck has been mapped means that it can be brought to the surface in a new way: with 3D printing. They would be sort of the world's first tourists. It's ship a connected to the building of Sweden. A three-man team, comprised of the two Lundgren brothers and Skogh, went in to investigate. In 1953 and 1976, marine explorer Jacques Cousteau led the next expeditions to the wreck, bringing an assortment of objects, including more statues, coins, and gemstones. Amanda Kooser. We can't even imagine. After what Harris describes as "six very long, monotonous years staring at the sonar waterfall display cascading down the screen, often for very, very long hours--sometimes 16 hours a day--bobbing around on the ocean, turning a little bit green as we concentrated on the data all the while," in September last year, an image loomed out of the sonar data. "In 2012, we made a photo mosaic of the whole site with 600 pictures put together. What are they actually importing and exporting, what are they producing, what are they consuming? The ancient coil-shaped artifacts were found in Russia’s Ural Mountains. For over four hundred years, the wreck and its rumoured treasure had slept 75 meters beneath the Baltic Sea. Much of the coming archaeology of the Mars will be done on dry land, using a computer, rather than by divers. There was an attempt to make Sweden a European superpower and Mars was part of that concept ... maybe the biggest ship in the world in the 1560s.". Or something else entirely? But before they send divers down, the team will first use a robot to map the wreck and the seafloor around it. This website uses cookies to improve user experience. Over the course of Ocean Discovery's search, the team had found tens of wrecked wooden ships maintained in a good state by the Baltic waters, located using the trawl snag data from the fishermen, but none had been the Mars. "You won't have to pay a decompression penalty. Defence Research and Development Canada, the military's technology arm, lent the archaeologists a tool that uses a jet of hot water to cut through ice. "The first indication [it was the Mars] was the size of the wreck. when we saw the first pictures from it, we recognised the ship's [building] techniques... it was in many ways similar to the Mary Rose. Parks Canada's Ryan Harris points to the sonar image of the HMS Erebus. A piece of the ship's hull 40 meters long had appeared, giving the first suggestion that the team had finally stumbled on the flagship of Swedish King Erik the XIV's fleet. Navigating an ROV on a complex wreck site like that is hard. "There are guns still sitting in wood, and cannonballs have penetrated into the hull. It was really, really huge on the sea bottom. Unless a whaling ship had made it up to the Queen Maud Gulf without being noticed, the team were likely to be the first people to see either the Erebus or the Terror in over 160 years. New robotic scuba exosuit acts like a mini submarine that helps humans stay longer in the deep sea. Due to the depth of the wreck and the diving technology of the period, divers could only spend a handful of minutes investigating the ship at a time or risk the bends that proved fatal to the first expedition. Even traces of the ancient grain may still be hidden in the sands around the wrecks for those with the right tech to find it. As the ship was loaded up with grain, which could take a couple of months, they would tour around and then get back on the ship at the end of the season.". Even the few bones around the wreck can give up their secrets without being moved. A second ship travelling in convoy with the Antikythera? While the grain is long gone, it will have decomposed to leave characteristic starches and structures called phytoliths, which can be detected with a powerful enough microscope. "A lot of people have said to us, 'Oh, a new Vasa ship, how should we be able to pay for the conservation and everything?' Many attempts had been made to find her since her loss on the first day of the Battle of Öland. Further dives in the weeks following after the discovery of the wreck were used to map the wreck's guns, and found that some bore the Vasa coat of arms. That has been an important part of the whole technology development to do that," Rönnby said. Those that have already been exploring the photo mosaic have been doing so at their desks, looking for artefacts or other elements the divers may have missed. Ancient Finds 1 / 40 In this image made available by the Egyptian Supreme Council of Antiquities on April 26, 2011, parts of a statue are seen during the excavation of an area close to the Temple of Amenhotep III, "1390-1352 BC" in western Luxor, where the largest statue of King Amenhotep III, so far. “There are dozens of items left, this was a ship bearing immense riches from Asia Minor,” Dimitris Kourkoumelis, an archeologist on the team, told AFP. The Antikythera, however, may have been built for a mix of business and pleasure. The team had another novel piece of technology at its disposal: a 7.5-meter autonomous underwater vehicle, the Arctic Explorer. In three or four days, they would be on top of the wreck before Ocean Discovery had had time to register the discovery as its own. A Secret Tunnel Found in Mexico May Finally Solve the Mysteries of Teotihuacán The chance discovery beneath a nearly 2,000-year-old pyramid leads to the heart of a lost civilization While it's common for wrecks to be found broken and battered, much of the ship--later confirmed as the Erebus--was still intact. Watering Ancient Rome ... springs do not always bubble up to the surface. Essentially it uses a whole bunch of still photos, and software is able to determine the three dimensional relationship between subsequent exposures and produces a three dimensional model or a point cloud of what the camera saw, so in just a couple of hours you can aquire a whole bunch of data and produce three dimensional images of the entire wreck site.". It’s believed that this complex clock-like device was used by ancient Greeks to calculate the movement of the stars and planets. The conditions in the Baltic Sea--the temperatures and absence of shipworm, which can destroy submerged timber--mean any ships that have sunk in its waters are often well preserved. The team changed its survey grid, aligning it with the axis of the ship, shortening the range of the sonar and boosting its resolution. A gale had stirred up sediment under the water, but a mix of luck and judgment allowed Harris and his divemate to find enter the water near a timber that Harris could follow "hand over hand" to the wreck proper. "The ancient grain carriers weren't just cargo ships, they were more like RMS Titanic. We did see the intact hull side but we didn't see any gun ports. I would like to use Mars as part of a general humanistic discussion about warfare and people in war. All workers on the boat will give cheek swabs to make sure their genetic material can be identified if it ends up on the bones accidentally. That's not to say that the Mars won't be seen above water in future, though. "All those data at the end of the day are incorporated into the maps. Last year, WHOI experimented with a fusion of the two: an Iron Man-like exosuit. You are really close to the battlefield. One day in 2011, the team had been tracking debris from a wreck site for some hours after finding some masts when something out of the ordinary loomed into view on its side scan sonar. However, without any scuba gear on the survey boat, the first up close look went to a robot, the Saab SeaEye falconer remotely operated vehicle (ROV). In 2011, the searchers drafted new technology to aid the search: aircraft equipped with lidar symmetry, which could scan the shore areas to a depth of around 20 meters. Under oceans across the world, hundreds of shipwrecks lie silent and forgotten. A second wreck--mentioned in passing by Cousteau's team but never really explored--had been keeping the first, better-explored ship company all these years, practically untouched. Its hull planks are some of thickest seen in antiquity, indicating the true size of the ship could be over 200 feet in length, putting it in the same ballpark as HMS Victory, the warship commanded by Admiral Lord Nelson during the Battle of Trafalgar--some 1700 years after the Antikythera sailed. You need to take diving technology and rebreathers and a lot of lamps, of course," said Rönnby. Antikythera Mechanism, ... were the first civilizations to have underground pipes, carrying water. The Antikythera mechanism was named after the shipwreck on which it was discovered. Using an algorithm called SLAM (simultaneous localisation and mapping), the imagery from the stereo cameras can be knitted together to make an extremely precise map of the seafloor. When the Mars sank in 1564, it was perhaps the biggest ship in the world--a fearsome vessel with over one hundred guns and 700 men onboard. It's a situation that Franklin and his men would have been familiar with. A separate remotely operated vehicle (ROV) carrying metal detecting equipment is also being used to spot hints of bronze or iron-carrying objects lying in the water. Since archeologists have previously only been able to operate at a depth of 60 meters, the team is confident that their month-long expedition will yield many other artefacts. "It looks like a chest exploded with silver coins.". Finding more of the statues "would be quite a big contribution to art history and culture but we also expect that in amongst the fragments of the statues will be other amazing things. The similarities between the two wrecks raised questions. The former rivals are now friends: Ocean Discovery, MMT, and the University of Södertörn formed a joint project to investigate the wreck. Unlike the humans that operate it, it can stay underwater for 72 hours, and was packed with all sort of tech: inertial guidance systems and doppler velocity logs to plot the position and speed of the vehicle, as well as an interferometric synthetic aperture sonar (InSAS) system that can record a far wider swathe of radar (630 meters) than the towed side-scan sonar system the survey boat normally uses. However, often they're used as observers, with the most difficult work still done by humans. After the death of one diver and two others becoming paralysed, operations to recover the artefacts were brought to a halt, but not before statues, ceramics, and the mechanism itself were brought up. Police found more than just homes down there, though. If an object located on a 2D image is worthy of further scrutiny, its location can be found using the multibeam, and a diver sent down to precisely the right place. "We could see, for example, a herringbone pattern of diagonally-laid upper decking, which is a laminate construction, sort of a second layer of decking laid over the first. The Inuit reported seeing one of the ships go down off the coast of King William island in around 1850, and they would be the last humans to lay eyes on the vessels for the century and a half that followed. The Mars expedition team also took it a step further and 3D printed the shipwreck to explore it even more. Ancient underground lakes discovered on Mars. Thousands more photos have been added since, and divers will carry on adding more, thanks to funding from both National Geographic North European Fund and Waitt Institute. In the Victoria Strait search site, there was too much ice to deploy it; in the Queen Maud Gulf, the waters were too shallow for it to be used safely. The advent of computing began before the birth of Jesus, with a small bronze mechanism that was lost under the sea off Crete for over a thousand years. 'First Ever Etruscan Pyramids Found in Italy'. They took the bait and came over." Among the techniques used to research the Mars was photogrammetry: divers took hundreds of normal digital still photos of the site from many angles, which is then sewn together by photogrammetry software to create a two-dimensional map of the site. So far, a not-to-scale section of the hull and one of the guns have been printed out. The team knew had almost certainly found one of Franklin's ships. "It's more technology for locating, not for marine archaeological survey.". Image source . We could see on the sidescan sonar pictures that this was a big, big wreck. During a few days in June, the robot created 10,500 square meters of map, with a resolution of 2mm. Now, after time and technology has moved on, the Greek government invited a team from the Woods Hole Oceanographic Institution (WHOI), headed by Dr. Brendan Foley, to begin the first significant excavation of the wreck since the Frenchman's over 40 years ago. ", It took some time to confirm the exact identity of the wreck after its initial discovery, however. While the Danish and German soldiers must have known the risks of a ship that was already alight, they still ventured aboard. "The couple of extant literary references to grain carriers refer to these floating palaces: mosaic floors, libraries, and amazing cabins, well appointed for the passengers--the 200 or 300 passengers that could be aboard from Rome to Egypt or the Black Sea. It's an object out of time: no other artefact as complex was built during the thousand years after the mechanism's creation--that we know of. Ocean Discovery had won enough time to confirm the identity of the Mars and record it with the authorities. ", The ships that were sent to find Erebus and Terror five years later had already had their bilge pumps upgraded to the newer Daunton model. Sign up today to get weekly science coverage direct to your inbox. You couldn't have scripted it better, almost everything you looked at was just so remarkable.". Erik had built maybe the biggest ship in the world in the 1560s, so Mars was a special ship. Over the years, the expedition had narrowed down its search to two areas, one in the Victoria Strait, another in Queen Maud Gulf, prompted by testimony from local Inuits who reported going aboard the vessel after its desertion by Franklin's men. Guildhall is a Grade I-listed building in the City of London and has been used as a town hall for several hundred years and the ceremonial and administrative centre of the City of London and its Corporation. Using a satellite system called AIS, which allows ships to know the location of nearby ships, Ocean Discovery could see a rival team from underwater survey business Marin Mätteknik (MMT) were also nearby and looking for the warship. Still it was not enough to put the wreck's identity beyond doubt: another 16th century Swedish warship, the Svärdet, had sank in the same region as the Mars and not long after. Harris said, "It's an extremely important tool for us now. Any artefacts, such as mosaic pieces, would lend credence to the theory, but more evidence could come from the bones of passengers that died when the ship sank. Like the mechanism that it carried, the Antikythera is unique for its time period. Abandoning the historical data and information from fishermen, the team resorted to doing search passes over the area, dragging the sidescan sonar from east to west. Thanks to the photogrammetry, BlueView, and multibeam sonar imagery of the wreck, the Mars can now be explored in great detail without putting divers tens of meters down in the freezing Baltic. Multibeam sonar, provided by MMT, gives highly accurate georeferencing, so archaeologists known where the wreck is and where each object can be found. In the next few years, would-be marine archaeologists will have yet another way to explore the Mars without getting their feet wet: the hope is to create a virtual reality version of the wreck, that individuals can explore through an Oculus Rift headset. In 1986, it eventually rose to the surface and beached itself on the shore of the Sea of Galilee. As they swam over the wreck, gradually distinctive cannons began to appear: first just one, caught in the beam of a single diver's flashlight, then five, six, seven piled up on top of each other. Archaeologists have started clearing an underground pyramid-shaped vault, the top part of which has been used as a wine cellar in recent times. World's First Computer Rebuilt, Rebooted After 2,000 Years A British museum curator has built a working replica of a 2,000-year-old Greek machine that has been called the world’s first computer. "We thought this was going to be the best technology to be used for underwater archaeology because we were hoping that the InSAS system would be able to detect very small, otherwise difficult-to-detect, cultural targets--detached rigging, rope lying on the seafloor, piece of iron plating lying flat on the bottom, any oars, or anything that might be difficult for us to detect with towed sonar," Harris said. The Mary Rose, a 16th century English warship and the pearl of King Henry VIII's fleet, was sunk ten years before the Mars and salvaged thirty years before it. Investigators had only scratched the surface of the Antikythera in the last nearly two thousand years. Nicknamed the “Big Fat Greek Expedition,” archeologists this week have embarked on a new mission to explore an ancient wreckage where one of the most complicated scientific antiques in existence was discovered over 100 years ago in the Aegean Sea. When they took to the seas, some of these vessels were the state of the art, laden with some of the most advanced technology of their era. Having found the Mars after a two-decade search, Ocean Discovery found that they weren't the only wreckhunters who were in the region. “The underground city [was found] in the 45 hectares of the total 75 hectare area that is within the transformation project,” he said. The crewmen never made it to safety, and subsequent investigations of remains, found over 100 years later, found traces of starvation, lead poisoning, scurvy, pneumonia, and cannibalism among the party. "With all of these types of ceramic artefacts, they're empty now, but we can take swabs and using police forensic techniques we can pull ancient trace DNA from the ceramic matrix of the original contents, down to the species level," Foley said. "That's when we saw the two brass six-pounder cannons," said Harris. One suggestion was that they were desperate to recover the thousands of valuable silver and gold coins the ship was said to carry, even if it meant risking--and ultimately losing--their lives. The ROV surveying couldn't prove it was the Mars, it could only prove it was a large warship," Lundgren added.
