Seagull is a multi-mission USV platform boasting high autonomy levels and modular features, allowing it to be rapidly reconfigured for a wide array of missions – including anti-submarine warfare and mine countermeasures.“Elbit Systems’ Seagull USV is one of the most advanced ocean drones in the world,” said Karl Kenny, Kraken’s President and CEO. “With KATFISH integrated on Elbit’s Seagull USV, the system can provide remotely operated, unmanned

Exploring Deep-seafloor Mineral Deposits

mineral deposits, which can provide vital new metals for emerging technologies, including those that will reduce greenhouse gas emissions, were formed by hot springs on the seafloor. The big question facing geologists is whether these deposits – the vast majority of which now lie under a blanket of marine sediment – still contain valuable metals. Have the minerals dissolved since they formed thousands of years ago beneath the Earth’s crust, or become even more concentrated?Project ULTRA will set out to  address these questions using a robotic drilling rig to drill the deposits. This

LRAUV: Arctic Oil-Spill-Mapping Robot Put to the Test

As commercial shipping and energy activities picks up in the Arctic region, the prospect of accidental oil spills in this pristine environment remain a concern. In response, the U.S. Department of Homeland Security (DHS) is taking the lead – through the U.S. Coast Guard – to develop a subsea robotic system to map and report on spills.“Because of ice coverage and the tyranny of distance, it is difficult to get resources and assets up in the Arctic in a quick manner,” said Kirsten Trego, Executive Director of the Coast Guard’s Interagency Coordinating Committee on Oil

Admiral Tim Lowe to Head UK Hydrographic Office

replacement is sought for John Humphrey, the current Chief Executive and Accounting Officer of the UKHO, who will leave at the end of January 2019.Rear Admiral Lowe said: “I look forward to taking the helm as Acting Chief Executive, whilst we continue to transform the UKHO into a world-leading marine geospatial information agency. It is an exciting time for our team as we transition to a data centric, digital first organisation whilst continuing to deliver on our wide spectrum of responsibilities, including our obligations to support safe passage in UK waters, provide hydrographic services to

I think we've come out of the era of being the blind man with the stick," said Robert Larter, a marine geophysicist at the British Antarctic Survey."We can survey much more efficiently - and, not only that, but in much greater detail," he said, adding that the work was painstaking."The ocean's a big place!" he said.The advent of new technology such as underwater drones and
