Core Insights - The article discusses a significant Arctic scientific expedition that utilized China's first domestically designed icebreaking research vessel, "Exploration No. 3," and the manned submersible "Fighter" to explore the depths beneath the Arctic ice, revealing critical geological secrets [1][6]. Group 1: Expedition Overview - The expedition lasted 98 days and involved deep-sea exploration at the Gakkel Ridge, known for its slow geological expansion rate of less than 20 millimeters per year [1]. - The team faced challenges in retrieving the submersible due to thick sea ice, which required innovative solutions for safe recovery [2]. Group 2: Technological Advancements - The "Exploration No. 3" vessel is approximately 104 meters long with a displacement of about 10,000 tons, capable of breaking through 1.2-meter-thick ice at a speed of 2 knots [6]. - The "Fighter" submersible underwent modifications to operate effectively in extreme Arctic conditions, allowing for precise navigation and operation without satellite signals [6]. Group 3: Scientific Contributions - The expedition successfully collected valuable samples, including water, sediment, rock, and biological specimens, which will aid in understanding rapid climate changes and life evolution in polar regions [6]. - The research emphasizes the importance of interdisciplinary collaboration and efficient communication mechanisms for future Arctic explorations [3].
