A new project has been announced to reduce the potential environmental impact of future mining by making exploration for deep-seafloor mineral deposits much more effective. ‘Project ULTRA’ has been funded by the Natural Environmental Research Council (NERC), and will be led by Professor Bramley Murton at the National Oceanography Centre (NOC).Deep-seafloor mineral deposits can provide vital new metals for emerging technologies, including those that will reduce greenhouse gas emissions. Many deposits were formed by hot springs on the seafloor and the vast majority of these now lie under a blanket of marine sediment. The big question facing geologists is whether these buried mineral deposits 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 address these questions using a robotic drilling rig to drill the deposits – this will also generate the first three dimensional image of the deposits, using scientific instruments on the surrounding seafloor to listen to vibrations from the drill as it bores through the seafloor. The boreholes will then be sealed and returned to a year later, when fluids will be tapped-off from the plugs to test for reactions deep inside the deposit, NOC explained.The rock core taken by the drill, and these fluid samples, will reveal the composition and structure of these types of mineral deposit, their sub-seafloor fluid pathways, alteration of the host rock, and the preservation processes of their ore minerals.By using this information to identify where the most valuable metals are located in the deposit, Project ULTRA will help ensure any future exploitation would be able to minimize the disturbance to the seafloor and its surrounding environment.This project forms part of the NOC’s ongoing research into seafloor resources and is a collaboration with the British Geological Survey (BGS), the Universities of Southampton, Cardiff and Leeds, Memorial University in Canada, as well as Oxford Museum, GEOMAR, Nautilus Minerals, VNIIOkeangeologia from Russia, and SMD.
0Shares0000Barcelona coach Ernesto Valverde thinks that manager Antonio Conte is Chelsea’s biggest strengthLONDON, United Kingdom, Feb 21 – Chelsea manager Antonio Conte had only kind words for Andreas Christensen despite his costly error in Tuesday’s 1-1 draw with Barcelona in the Champions League.Willian gave the Blues the lead after twice hitting the post at Stamford Bridge, but a misplaced pass from the Dane allowed Andres Iniesta to tee up Lionel Messi for an away-goal equaliser. “It was a great performance, an incredible performance,” Conte said after leaving club captain Gary Cahill on the bench to go with Christensen, Antonio Rudiger, and Cesar Azpilicueta in central defence.“He is only 21 and it is great he can play with that maturity. He was one of the best players. He played a top game and I am very pleased for his performance.“I don’t remember a great save from Thibaut. They had the one chance in the first half with Paulinho and then the second half with [Luis] Suarez.“I think we played a really good game and I must be pleased because my players made a great effort. They followed the plan, the programme we prepared.“They showed themselves to be a really strong team, a fantastic team, but we showed that if we are ready to work very hard together defensively but at the same time when you continue to have the right feeling with the ball to create the chance to score I think that we can try to do something incredible at Camp Nou.”0Shares0000(Visited 1 times, 1 visits today)
