【人民日报】潜心探索地球深部的奥秘

Core Insights - The article discusses China's advancements in polar deep-sea exploration, highlighting the successful use of indigenous technology and equipment in extreme conditions [2][7]. Group 1: Exploration Achievements - The team conducted a 98-day Arctic expedition, utilizing the domestically designed icebreaker "Exploration No. 3" to perform manned deep dives in the Gakkel Ridge, an area with over 80% ice coverage [2][3]. - The Gakkel Ridge is noted for its slow geological expansion, providing critical insights into Earth's evolution and the deep mantle [2][3]. Group 2: Technological Innovations - The "Fighter" manned submersible, modified for extreme conditions, successfully navigated under ice, overcoming challenges such as ice cover and communication issues [3][7]. - A new operational model was developed where the submersible could locate the mother ship through advanced acoustic communication, enhancing safety during operations in dense ice [3][7]. Group 3: Scientific Contributions - The expedition collected valuable geological samples, including basalt, which are essential for understanding the formation of the ocean floor and the deep mantle [3][4]. - The research aims to contribute to the understanding of rapid climate change in the Arctic and the evolution of life in extreme environments [7]. Group 4: Future Prospects - The article emphasizes the need for interdisciplinary collaboration and efficient communication mechanisms to maximize the use of polar samples and data in future research [4][6]. - The advancements in deep-sea technology during the "14th Five-Year Plan" period position China as a leader in polar exploration, capable of conducting continuous manned deep dives in Arctic ice-covered regions [7].
