Core Insights - The "Marine Geological No. 6" research vessel successfully completed its 15th deep-sea geological survey mission, returning to Guangzhou with multiple significant findings [1][3] - The mission lasted 95 days, covering a total distance of 12,673 nautical miles, focusing on deep-sea environmental surveys and the application of key detection technologies and equipment [1] Group 1: Research Achievements - The vessel conducted a sea trial for the seabed electromagnetic collection station, achieving a maximum deployment depth of 7,663 meters and obtaining high-quality electromagnetic observation data [1] - A batch of marine environmental data and samples, including deep seawater, seabed sediments, polymetallic nodules, and marine organisms, was collected to support deep-sea geological research and marine environmental management [1][3] - The research team discovered a polymetallic nodule resource-rich area during the seabed mineral geological survey [3] Group 2: Technological Innovations - The mission marked the first joint high-precision test operation of a 6,000-meter deep-sea remotely operated vehicle and an autonomous underwater robot in the Pacific deep-water area [1] - The introduction of soilless cultivation technology, combined with existing soil-based cultivation methods, successfully provided fresh vegetables throughout the voyage, improving living conditions for long-duration oceanic research missions [3] Group 3: Future Plans - The "Marine Geological No. 6" vessel is scheduled to return to the Pacific in the first half of 2026 to conduct further basic geological and environmental geological scientific investigations [3]

Core Viewpoint - The successful launch of China's first independently designed and built deep-sea drilling vessel "Dream" marks a significant advancement in the country's deep-sea exploration technology and capabilities, breaking multiple world records and establishing a new benchmark in the industry [1][7]. Group 1: Vessel Specifications and Capabilities - "Dream" has a maximum drilling depth capability of 11,000 meters, making it the only deep-sea drilling vessel globally capable of penetrating the Mohorovičić discontinuity (Moho) [3][4]. - The vessel's total length is 179.8 meters, width is 32.8 meters, and height is 81.2 meters, equivalent to a 25-story building, with a maximum variable load of 15,000 tons [3][4]. - It can operate for 120 days without resupply and withstand super typhoons of up to level 16, improving operational efficiency by 60% compared to foreign counterparts [4][5]. Group 2: Technological Innovations - "Dream" features a modular design that integrates functions for ocean scientific drilling, deep-sea oil and gas exploration, and natural gas hydrate investigation, which is a significant challenge globally [1][4]. - The vessel includes the world's first hydraulic lifting drilling machine that combines oil and gas exploration with core drilling capabilities, enhancing drilling efficiency and hard rock penetration [4][5]. - It houses a comprehensive onboard laboratory with nine experimental functions, making it the largest and most versatile "mobile laboratory" at sea, with nearly 40% more space than foreign vessels [4][5]. Group 3: Strategic Importance - The construction of "Dream" breaks the long-standing foreign monopoly in the deep-sea drilling vessel sector, positioning China as a leader in this field [5][6]. - The vessel's capabilities allow China to independently organize ocean drilling expeditions, transitioning from a participant to a leader in global ocean exploration [7]. - "Dream" is expected to significantly contribute to the understanding of Earth's internal structure and support global scientific endeavors to explore the unknown [7].
