ancient computer found underground

The expedition is also experimenting with laser scanning, in partnership with Canadian firm 2G Robotics which makes underwater scanners normally used for detecting damage on oil pipelines. The only other known ships of the era that were larger were the pleasure barges that the Roman emperor Caligula used to cruise across Lake Nemi. "Out of the gloom on the seafloor loomed this stately shipwreck site, standing bolt upright. Using DRDC's 'hot water knife', a two meter section of the ice was removed, allowing the divers to slip beneath the ice and onto the wreck site. While the WHOI team didn't use the experimental suit for any work on the wreck site, it was tested out on the vicinity of the Antikythera, and the organisation is now considering whether to plough ahead with a development program. By comparing the lead's isotope profile to other samples from around the world, the researchers will be able to hone in on where the ship was built, or where it sailed from. "They were one of the first things we saw as we crept over the seafloor to the site. Enlarge Image. Now, thanks to the most advanced tech of our time, some long-sought wrecks are finally being found and explored for the first time. origins would be exciting to say the least. 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. Harris said, "Things were changing so very quickly in that sort of industrial period that this is like a snapshot of what things were like in 1845.". Kinkaid, who claimed to have found deep within the bowels of the earth in the Marble Canyon region of the Grand Canyon a vast cavern system with … 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. You need to take diving technology and rebreathers and a lot of lamps, of course," said Rönnby. "All those data at the end of the day are incorporated into the maps. Sign up today to get weekly science coverage direct to your inbox. Everything was just so picture perfect. Image source . "Halfway through, we found a wreck that looked like nothing else," Ingemar Lundgren said. As well as documenting the outside of Erebus and its location, the Parks Canada team face the difficulty of navigating within the ship itself, mapping the location of the objects within it and any subtle associations with them. Then we had a good indication it was very likely that it was Mars," Rönnby said. Since the discovery, archaeologists have found over 50 historical artifacts in the underground city and most of them have already been persevered. When the scuba gear arrived, human divers were able to see the site for the first time. 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. The team had another novel piece of technology at its disposal: a 7.5-meter autonomous underwater vehicle, the Arctic Explorer. The Mars met its end in a bloody sea battle between Sweden, which had built the formidable warship, and the combined armies of Denmark and the German province of Lübeck. 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. It's absolutely typical of royal navy dockyard modifications for Arctic service," said Harris. Sometimes they would dig down to the water table and build an underground tunnel to begin the aqueduct. 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. While it's common for wrecks to be found broken and battered, much of the ship--later confirmed as the Erebus--was still intact. The $1.3 million exosuit will allow the team to dive to depths of 150 meters (492 feet) and carefully explore the ship for several hours. After the boat skeleton was found, experts immediately set to work in dating the old wreckage. We know they could follow us on AIS," Ingemar said, "so we set up a search pattern away from the wreck site and we made it look like we had found something. 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. Remains of four people on the wreck have been found so far, and more may still be on the wreck. "Even the maps for the coastline of this area weren't terribly accurate. Using sidescan sonar and multibeam sonar, the project began to build up a high-resolution three-dimensional picture of the wreck too. Said Harris, "It can resolve a target the size of your thumb anywhere in that sonar record, because it's using almost like synthetic aperture radar--it's using multiple radars and its synthesising that into one coherent very, very accurate image.". The flames ignited the gunpowder stored on the ship causing a huge explosion that blew out the stern of the ship and took her, and the men aboard her--the Swedish sailors and invading forces alike--to the bottom of the ocean. “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. "You can stay for hours and hours doing work or observing work, and then be winched right back up to the surface," said Foley. "It's fun for us, because we feel like we've opened up a whole new vista on the past. The ancient coil-shaped artifacts were found in Russia’s Ural Mountains. The divers move through the water, iPad in hand, looking for the points of interest from the heat maps, and checking their position against those locations as they go. "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. "It's more technology for locating, not for marine archaeological survey.". That has been an important part of the whole technology development to do that," Rönnby said. Archaeologists in Cambodia have found multiple, previously undocumented medieval cities not far from the ancient temple city of Angkor Wat, the Guardian … During the battle, the Mars caught fire but despite the clear danger, the Mars was still boarded in the last minutes above the waves by enemy forces. A four man team--Richard Lundgren, Fredrik Skogh, Christoffer Modig, Anton Petersson--were on board the ship when it found the Mars, and sent a picture of the scan to Ingemar Lundren, who was processing images from the vessel onshore. Exploring another cave in Arkansas, just north of Batesville, explorers found a tunnel illuminated by a greenish phosphorescence where they met a race of beings who stood 7 to 8 feet tall and had bluish skin. The divers use rebreathers to allow them to investigate the wrecks at depths that would normally prove fatal to humans in a matter of minutes. The Parks Canada returned every year, surveying the two areas for traces of the lost vessels. "We tried to distract them. A lost city discovered deep in the Amazon rainforest could unlock the secrets of a legendary tribe. In time, however, the BlueView point cloud will be merged with that from the multibeam sonar so the two technologies can fill in any gaps from each other. 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. If the ship had to carry statues, some up to three meters tall, they'd have to be packed well to prevent damage in transit. "I said it could well be the Mars, because it looked so different. It was absolute exhilaration.". 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. That's where we're able us to use different technological approaches to document the site that work a lot a better.". Sept. 30, 2020 6:28 a.m. PT. Ocean Discovery's divers had started their search decades ago, upgrading from echosounders to sidescan sonar in 1999. if you're trying to steer a survey line and not run into an island, 4km is fairly significant," said Ryan Harris, who led the Parks Canada team. Thought to have been built at the end of the second century BCE, the Antikythera mechanism is considered the first programmable computer. The project is also working with a BlueView sonar scanner from MMT, which when positioned on the seafloor can gather 60 million measurement points in 15 minutes. It's thought the two vessels, HMS Erebus and HMS Terror, were abandoned when they became icebound, leaving the crew to begin a trek on foot across Canada in the hope of finding supplies, or human settlements along the way. A PhD student is studying the 3D mosaic, finding out the physical characteristics of the person--their height, whether they had certain diseases--and even how they died by studying fractures or burns on the bones. To preserve them, protect them, and interpret them for the public, obviously we have know where both of them are. Combined with the million photos taken by divers, a map that's precise to two millimeters has been built up--higher resolution than the multibeam. 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. One hypothesis is that the Antikythera may both have carried early tourists and freight, thanks to the huge bronze and marble statues it transported as cargo.
