在海底捡“特产” 给地球做CT

Core Insights - The "Marine Geological No. 6" research vessel successfully returned from a 95-day expedition in the Pacific, uncovering significant scientific findings, including polymetallic nodules that have been dormant for 30 million years [1][3]. Group 1: Research Achievements - The expedition utilized a combination of self-developed deep-sea remotely operated vehicles and autonomous underwater robots for high-precision sampling and data collection, marking a significant advancement in deep-sea exploration technology [3][4]. - The polymetallic nodules discovered are rich in metals such as cobalt, nickel, copper, and manganese, which are crucial for enhancing mineral resource security. These nodules grow extremely slowly, taking millions of years to form, and provide insights into historical oceanic environmental changes [4][5]. - The research team conducted the deepest electromagnetic profile measurement in China, reaching depths of 7,663 meters, which allowed them to analyze the Earth's internal structure and dynamics, revealing a critical "cold-hot" interface approximately 50 kilometers below the seabed [5][6]. Group 2: Biological and Geological Insights - The expedition also focused on deep-sea biological resources, discovering unique microorganisms and deep-sea corals that have significant implications for understanding life's origins and climate evolution. These organisms may have applications in biomedicine and other industries [8][9]. - The data collected will support future ocean drilling projects, with plans for advanced drilling operations in the South China Sea, aiming to further explore the mysteries of the deep ocean and its impact on global climate and geological processes [9].
