Core Insights - The Ministry of Natural Resources' South China Sea Investigation Center has completed a record 31 synchronous hydrological observation stations in the eastern Guangdong sea area, marking a historical high for synchronous tidal observations in the South China Sea [1] - The observations aim to comprehensively understand the spatial and temporal distribution characteristics of hydrometeorological basic elements during typical summer tidal periods, providing critical data support for the planning, design, and construction of offshore wind farms in the region [1] Observation Details - The 31 tidal hydrological observation stations were established at distances exceeding 100 nautical miles from shore, with a maximum water depth of over 60 meters, an average distance from shore of over 60 nautical miles, and an average water depth of over 30 meters [1] - The field investigation coincided with the end of the 2025 fishing moratorium and the onset of the fishing season, as well as the presence of typhoons "Swordfish" and "Blue Lake" in the South China Sea, making the task challenging and time-sensitive [1] Operational Challenges - To successfully complete the mission, the investigation center conducted thorough plan verification and meticulous expedition planning, receiving strong support from various marine centers in Shantou, Haikou, and Shenzhen [1] - The field investigation team scientifically designed the voyage plan, accurately grasping favorable operational timing while overcoming numerous adverse factors such as dock congestion, harsh sea conditions, deep water stations, and continuous operations [1]

Group 1 - The article highlights the dedication and efforts of workers in the marine sector, emphasizing their role in safeguarding ecological safety and exploring marine mysteries during the International Labor Day [1] - The Ministry of Natural Resources has been conducting frequent ecological monitoring in the South China Sea, with the latest investigation being the seventh since October of the previous year, aimed at studying disaster biological outbreaks and ecological risk monitoring [3] - A spring survey was conducted by the South China Sea Investigation Center near Shantou, focusing on the environmental status of offshore wind power projects, collecting hydrological data essential for future marine development [7] Group 2 - The Zhuhai Marine Center's team conducted ecological environment monitoring at the Qingzhou offshore wind farm in Yangjiang, collecting samples of plankton and sediment to assess the operational impact on marine ecology [10][12][15][16] - Maintenance of various monitoring equipment was carried out by the North Sea Marine Center in Beihai, ensuring the functionality of sensors and analyzers for ongoing marine observations [19] - A tidal zone investigation was performed by the Sansha Marine Center, focusing on biological sampling and geomorphological surveys in the Xisha Islands [20][21]

Core Viewpoint - The article highlights a practical training session for marine survey outboard motor workboats organized by the South China Sea Bureau, emphasizing the importance of efficient and safe workboats for marine scientific investigations in the South China Sea [10]. Group 1: Training and Operations - A practical training session took place in the waters of Hongshengsha Island, Guangdong, with 60 frontline operators participating to master the operation and assembly skills of new workboats [10]. - The training included a series of rigorous assessments, covering tasks such as on-water engine replacement, maintenance, and practical operations, simulating real task scenarios [11]. Group 2: Importance of Workboats - The demand for marine scientific surveys and the duration of offshore operations have been increasing annually, making safe and efficient workboats crucial for the successful completion of major marine scientific tasks [10]. - The South China Sea Bureau has formed a task force to conduct specialized research on workboat hulls and engines, exploring new models for marine surveys that combine multiple operational points [10]. Group 3: Cost Efficiency and Operational Flexibility - The Bureau has equipped the "Xiangyanghong" series survey vessels with aluminum alloy workboat hulls and diesel outboard motors, allowing for operational flexibility and significant cost reductions in marine survey equipment [10].
