4、loration is now as close as the nearest computer. “Telepresence“ (远程呈现 ) technology lets scientists - and the public - join expeditions without leaving dry land. A just completed expedition to the Lost City, an unusual undersea vent formation in the Atlantic Ocean, showcased the technology. The proj
5、ect used a network of satellites and high-speed Internet access to connect participants across many miles of land and sea. During the expedition undersea explorer Robert Ballard and the crew aboard the National Ocean ic and Atmospheric Administration (NOAA) research ship Ronald H. Brown were anchore
6、d above the Lost City site. Meanwhile co-chief scientist Debbie Kelley and her colleagues were some 4,500 miles (7,250 kilometers) away on the University of Washington campus in Seattle. At launch on July 17 Ballard described the project as a “precedent-setting ocean expedition that raises the bar o
7、n use of communications technology.“ “Normally on a deep-ocean expedition, I talk with the missions chief scientist across a table on the research vessel,“ he said. “In this case we talk across the planet.“ Ballards Institute for Exploration (IFE) in Mystic, Connecticut, supplied its veteran robotic
8、 vehicles, Hercules and Argus, to do the diving. The robots sent high-resolution images taken some 2,100 feet (700 meters) below the surface to the Ronald H. Brown. The images were transferred via satellite from the ship to receivers at the University of Rhode Island in Kingston. They were then sent
9、 across country to the team at the University of Washington. All told, data from the Lost City travelled nearly 5,000 miles (8,050 kilometers) in less than two seconds. Technology Boosts “Crew“ Size, Expertise Real-time deep-sea images have been beamed around the globe before. Ballard, who discovere
10、d the undersea wreck of the Titanic in 1985 ,returned to the site in 2004 and sent images to scientists at the University of Rhode Island. But this time the lead scicentists directing the expeditions research operations joined the dive virtually. “We had a team of engineers and pilots who controlled
11、 the remotely operated vehicles (ROVs) and were taking instructions at all times from the University of Washington ( science team),“ Dwight Coleman said. Coleman is a professor of marine science at the University of Rhode Island and a colleague of Ballards at IFE. Only so many people can live aboard
12、 a research ship. And although a large vessel may accommodate a science party of 30, half must be engineers who maintain and operate the ROVs. The number of researchers is thus limited by ship space, as well as by scheduling, budgets, and other real-world concerns. Telepresence provides an intriguin
13、g(令人好奇的 ) solution. “When youre doing exploration, youre never sure what expertise youll need, because youre never sure what youll find,“ Coleman said. “This technology provides the capability to network in experts on a specific subject from around the world. You can invite everybody aboard the ship
14、.“ The technology seems to have a bright future. NOAA is converting a former U. S. Navy vessel, the U. S. N. S. Capable, into a research vessel dubbed the Okeanos Explorer (okeanos is the ancient Greek term for “ocean“ ). The ship will be specially outfitted for future telepresence missions. Of cour
15、se, telepresence technology isnt exactly like being at sea. In her online expedition log, co-chief scientist Deborah Kelley described the nearly surreal scene as Hercules first touched bottom. Kelley and her science team watched the action via cameras carried by. Argus, hovering some 100 feet (30 me
16、ters) above the seafloor. “This was a view like no other I had ever seen,“ she reported. “In the dark of the room at the UW with our first views of the bottom, I felt as if I was suddenly in the control room on the ship.“ “Later, walking out into the !it hallway in Mary Gates Hall, I was struck by t
17、he sharp contrast of being immersed within the environment of an ocean 4,500 miles away and nearly one half mile 0.8 kilometers down and that of a sunny Seattle day with Mt. Rainier in full view.“ A Natural Atlantis The Lost City is an undersea hot spring region unlike any other known to science. Ke
18、lley and her team at the University of Washington discovered the region by accident during a manned submersible(能潜水的 ) expedition in 2000. The site boasts dramatic, 90- to 200-foot-high (30- to 60-meter-high) carbonate “chimneys“ that vent methane(沼气 ) and hydrogen-rich fluids. The pale towers, whic
19、h host a great diversity of marine life, inspired the scientists to name their find after the mythical city of Atlantis. The site resembles undersea vent systems found along ridges in the seafloor where tectonic (建造 ) plates are spreading apart. Escaping hot volcanic gas at these vents creates a sun
20、less but nutrient-rich environment that sup ports creatures such as tubeworms, mussels, shrimp, and large clams. The vents, first discovered nearly 30 years ago, changed scientific perspective on how and where life can exist on Earth. The Lost City formation, found 9 miles ( 14 kilometers) from the
21、Mid-Atlantic Ridge, is the first evidence that other areas of the ocean could contain such ecosystems. Using ROVs in addition to manned submersibles, the scientists hope to learn more about the type of organisms that can thrive near hydrothermal systems. And thanks to telepresence technology, scient
22、ists werent the only ones who could join the most recent Lost City expedition from remote sites half a world away. Immersion Presents, IFEs sister organization, transferred live feeds and produced programs that allowed educators, Boys and Girls Clubs, museums, and libraries in the United States and
23、Mexico to take part. “We want to connect the general public to ocean exploration through satellite and Internet technology, “Coleman said. In fact, the live views from Hercules and Argus were often available to anyone, anywhere in the world, who had an Internet connection via the Immersion Presents
