Core Viewpoint - The article discusses the advancements in China's marine research capabilities, highlighting the delivery of the "Tongji" intelligent research vessel and its significance as a state-of-the-art mobile laboratory for oceanic studies [1][2]. Group 1: "Tongji" Research Vessel - The "Tongji" vessel is a 2000-ton next-generation green, silent, and intelligent research ship, set to complete comprehensive sea trials by May 2025, making it a powerful tool for scientific exploration [2]. - It is the first research vessel in China to obtain four intelligent symbols from the China Classification Society's intelligent ship standard i-ship (R1, No, E, I), capable of conducting comprehensive scientific investigations in various marine disciplines [5]. - The vessel is equipped with multiple scientific instruments, including single-beam and multi-beam measurement systems, shallow seismic profiling systems, and underwater remote-operated vehicles (ROVs) [5]. Group 2: Modular Laboratory Design - The onboard modular laboratory utilizes shipping containers as a framework, housing instruments for marine chemistry, biological testing, water quality monitoring, meteorological observation, and rock analysis, allowing for easy loading, movement, and expansion [7]. - Key equipment includes automatic nutrient analyzers, total organic carbon analyzers, inverted phase contrast microscopes, and ultra-low temperature freezers, among others [7]. Group 3: Other Research Vessels - Other notable research vessels include Xiamen University's "Jia Geng" vessel, which is China's first marine research ship designed abroad and built domestically, featuring over 550 square meters of research space [8][10]. - The "Science" vessel from the Chinese Academy of Sciences is the first of its kind with independent intellectual property rights, equipped with various systems for water, atmosphere, and seabed exploration [17][18]. - The "Dream" drilling vessel, designed for ultra-deep water research, includes nine specialized laboratories and is capable of operating in severe weather conditions [31][34].
