水下考古，从浅海迈向深海（科技自立自强）

Core Viewpoint - The article highlights the significant archaeological discoveries from the underwater excavation of two ancient shipwrecks in the Northwest Slope of the South China Sea, marking a historic breakthrough in China's underwater archaeology, transitioning from shallow to deep-sea exploration [8][10]. Group 1: Archaeological Discoveries - The "Deep Blue Treasure" exhibition at the China (Hainan) South China Sea Museum has seen a nearly 50% increase in daily visitor numbers during the summer, showcasing artifacts from the underwater excavation [6]. - The excavation revealed a large number of artifacts, including a stunning cloisonné peacock and peony-patterned jar, previously lying at a depth of approximately 1,500 meters [6][12]. - The discovery of two shipwrecks, one filled with porcelain from Jingdezhen and the other with imported hardwood, illustrates the prosperous two-way trade along the ancient Maritime Silk Road [11][15]. Group 2: Technological Advancements - The "Deep Sea Warrior" manned submersible, which has a working depth capability of 4,500 meters, played a crucial role in these discoveries, having undergone over a decade of technological development [10]. - The successful operation of the submersible in extreme conditions demonstrates the advancements in underwater archaeology technology, allowing for exploration in previously inaccessible deep-sea areas [9][10]. Group 3: Conservation Efforts - The exhibition employs a dynamic model of "archaeology, protection, and exhibition," allowing the public to witness the conservation processes of newly recovered artifacts [14]. - Newly recovered artifacts undergo a complex conservation process to prevent deterioration due to environmental changes after being brought to the surface [14][15]. - The conservation team at the museum is dedicated to preserving and restoring these artifacts, ensuring their longevity and historical significance [14][15].
