You need at least 5 people to form a company.Ģ. That effort will be crucial for accomplishing “all the things that we’re trying to do in the maritime environment,” he said.1. Moving forward, he said, both federal investment and public-private partnerships should focus on “getting every ship to be a sensor in the ocean.” “There are great opportunities for the people who understand this technology, to make new ways, better ways to actually map it faster,” White said. However, he said, the technology to do so is improving. “It’s like trying to map your backyard with ants, with the ships that we have.” “It’s hard to map the bottom of the ocean,” said Rear Admiral Jon White, president and CEO of the Consortium for Ocean Leadership. Projects like Seabed 2030 - a worldwide effort to map the seabed - will be crucial to these efforts, Smith said. They are turning to crowdsourcing, satellite-derived bathymetry - and the idea of turning every ship into a sensor. NOAA struggles even to model how water moves in the ocean without more information, he said. “Or environmentally important information.” “The other 59 percent, there’s potentially a gold mine of economically important information in there,” he continued. waters and coasts, they have at least one piece of information on only 41 percent of the ocean. Such maps are necessary to support development, including transportation, offshore energy, fishing and stewardship of natural resources, he said. One of NOAA’s top priorities, Smith said, is “the broad baseline mapping of the ocean - including the hydrography, the depth and form of the sea floor, and oceanography.” The “next generation of services” would go much further, predicting the water level, salinity, and other information with more precision and detail. “The traditional way that we have supplied these ships with information - with nautical charts and predicted tides and tide tables, and weather over radio facts - are not anywhere near close to being what’s necessary,” said Rear Admiral Shep Smith, director of NOAA’s Office of Coast Survey. In 2015, the Finnish icebreaker Fennica ripped a three-foot gash in its hull - while sailing within the relatively better charted waters of Alaska’s Dutch Harbor. In August, the Russian research ship Akademik Ioffe ran aground in Canada’s Arctic. Maps are becoming more important as shipping activity increases - both around the world and in the Arctic. As the ships traverse the ocean, they would help improve existing maps and information about the waters they tread. Ships outfitted with sensors could provide the very information they need to travel more effectively.Įach ship would collect information on oceans, atmosphere, ecosystems, pollutants and more. “How does every ship become a sensor?” Titley asks. But there could be an intriguing solution: crowdsourcing. The problem, he said, comes down to accumulating - and managing - data. And conversely, we were getting rid of sea mounts on charts that weren’t there.” When he was on active duty in the Navy, Titley said, “we were finding sea mounts that we had no idea were there. Titley spoke alongside several other maritime experts at a recent Woodrow Wilson Center event on marine policy, highlighting the need for improved oceanic maps. Navy Rea Admiral who directs the Center for Solutions to Weather and Climate Risk at the Pennsylvania State University. “Especially when you get up north, the percentage of charts that are basically based on Royal Navy surveys from the 19th century is terrifying - or should be terrifying,” said David Titley, a retired U.S. Only 4.7 percent of the Arctic has been mapped to modern standards. Even in the United States, which has some of the best maritime maps in the world, only one-third of the ocean and coastal waters have been mapped to modern standards.īut perhaps the starkest gaps in knowledge are in the Arctic. Throughout world, the ocean floor’s details remain largely a mystery less than 10 percent has been mapped using modern sonar technology.
