If you want to know what is under your house, you hire a surveyor. You do not buy the ground-penetrating radar yourself. Countries have mostly treated their seabeds the same way, and Norway was no exception. When the government wanted high-resolution maps of the ocean floor it owns, it paid private firms with the right robots to go and get them.<\/p>\n
The Norwegian Offshore Directorate says that arrangement is on its way out<\/a>. On Thursday, June 4, aboard the research icebreaker Kronprins Haakon in Bergen harbor, University of Bergen Rector Margareth Hagen christened<\/a> a 6,000-meter autonomous submarine and gave it a name: Unn 6000. Researchers left on a month-long cruise into the Norwegian-Greenland Sea, and the machine went to work.<\/p>\n The money came from Norway’s Ministry of Energy, routed through the Offshore Directorate as a grant to the University of Bergen. Kongsberg Discovery built the vehicle. “Now that we have access to our own advanced mapping resources,” said Hilde Braut, Assistant Director for New Industries at the directorate, the country strengthens both its knowledge base and its ability to manage the deep sea responsibly.<\/p>\n The timing is what makes this interesting. The same directorate is due to publish a fresh count of Norway’s seabed minerals this year, and the Norwegian parliament has closed the door on mining any of them until at least 2029.<\/p>\n Unn 6000 is a Kongsberg Hugin Superior<\/a>, a model the company introduced in December 2018 and still markets as the most capable AUV commercially available. The hull is rated to 6,000 meters, which covers essentially all of Norway’s deep water and most of the world’s.<\/p>\n Resolution is where owning the machine pays off. The Offshore Directorate puts ship-mounted multibeam mapping at roughly 20 to 50 meters of detail, which is fine for drawing a landscape and useless for spotting a chimney of metal sulphide sitting on a ridge. Kongsberg’s specifications for the HISAS 1032 synthetic aperture sonar put its imagery at about 5 by 5 centimeters.<\/p>\n Around that sonar the vehicle carries an EM2040 Mk2 multibeam echo sounder, a camera, a laser profiler, a sub-bottom profiler, a magnetometer, and sensors that sniff the water for methane, carbon dioxide and oxygen. Kongsberg says it covers about 4.5 square kilometers an hour while producing imagery and bathymetry at the same time.<\/p>\n Then there is the navigation, which is the quiet reason a machine like this is worth owning outright. Kongsberg’s published figure for real-time accuracy is better than 0.04% of distance travelled. Run it a kilometer and it knows where it is to within about 40 centimeters, with no GPS and nobody holding a cable.<\/p>\n A lot of the coverage has been sloppy about this, so it is worth pinning down. Unn 6000 is not Norway’s first state-owned underwater robot and not even Norway’s first Hugin. The Royal Norwegian Navy has run Hugin AUVs since the early 2000s, and in 2017 the Norwegian Armed Forces bought four more from Kongsberg for 155 million kroner, according to the Norwegian Defence Research Establishment. Those are rated to 3,000 meters and built for hunting mines.<\/p>\n It is also not the Hugin Endurance<\/a>, the long-range Kongsberg demonstrator that spent 15 days alone on the seabed without surfacing. That one belongs to the manufacturer.<\/p>\n What changed is who the machine answers to. Unn 6000 is operated by NORMAR, the Norwegian Marine Robotics Facility at the University of Bergen, the same outfit that runs the ROV \u00c6gir 6000. The name is not a coincidence. Unn is one of \u00c6gir’s daughters in Norse mythology, and the Old Norse Unnr<\/em> means wave, or sea. NORMAR notes the name also points at the job, which is mapping underwater habitats in the Norwegian deep sea.<\/p>\n Its first working cruise, in June, ran along the Mohns Ridge in the waters northeast of Jan Mayen, surveying seafloor geology, biological communities and ocean conditions alongside \u00c6gir. That is not a random patch of Arctic bottom. It is part of the volcanic ridge system where Norway’s sulphide deposits sit.<\/p>\n In its annual shelf report published in January, the Offshore Directorate said it plans to run a new resource assessment for seabed minerals during 2026<\/a>, based on the data collected in recent years, and mentioned the AUV purchase with the University of Bergen in the same paragraph.<\/p>\n The last assessment came out in January 2023, and every argument about Norwegian seabed mining since has been built on it. For sulphide deposits, the directorate’s expected values for resources in place<\/a> were:<\/p>\n Two things about that report get lost constantly. It measures resources in place, not recoverable tonnage, which is a different and much smaller number nobody has produced. And the directorate built it on four expeditions run between 2018 and 2021 plus academic data, backed by the roughly 1,000 mineral samples it had collected by 2024. Everything Unn 6000 brings back is an upgrade on that baseline.<\/p>\n Norway opened part of its shelf to mineral activity in 2024 and proposed 386 blocks for a first licensing round. Then on December 3, 2025, the minority Labour government cut a deal with the Socialist Left, the Greens, the Reds and the Centre Party to get the 2026 budget through, and seabed mining was the price<\/a>. No licences during this parliamentary term, which runs to 2029, and reduced public funding for state-led mineral mapping.<\/p>\n Companies that had built their plans around that round are absorbing it. Adepth, one of the Norwegian firms in the sector, told Mongabay after the vote that it would redirect its attention toward countries with comparable resources and more predictable regulation.<\/p>\n So the survey robot sails, the resource assessment gets written, and the licences that would turn any of it into an actual mining operation<\/a> do not exist. Norway is doing the homework for an exam that has now been postponed twice.<\/p>\n Which is arguably the sane order. A resource estimate built on 5-centimeter sonar makes a better basis for a political fight, in either direction, than one built on ship passes and a thousand rock samples.<\/p>\n The contrast with Washington is hard to miss. On July 16 the federal government announced a Proposed Leasing Notice<\/a> for the first American offshore critical-minerals lease sale in decades, covering blocks off American Samoa, with a proposed auction date of November 19 and comments from the territory’s governor due September 15. The agency running it, the Marine Minerals Administration, had been created six days earlier by folding BOEM and BSEE back together.<\/p>\n The baseline survey work is happening in parallel rather than in advance. NOAA’s Office of Coast Survey announced its three-month project to map more than 30,000 square nautical miles of federal water off American Samoa in January of this year, and the robots doing that kind of work<\/a> are only now getting cheap enough to run at scale. The government has been careful to say the notice does not guarantee a sale happens.<\/p>\nThe sonar is the expensive part, not the hull<\/h2>\n
