Core Viewpoint - The North Sea Bureau has implemented a series of proactive measures to enhance marine disaster prevention and response capabilities in the region, focusing on early deployment, advanced warning systems, and emergency drills to safeguard coastal communities during the flood season [1][7]. Group 1: Pre-Flood Preparedness - The North Sea Bureau issued pre-flood preparation and inspection notices in March and April, forming special inspection teams to conduct comprehensive on-site supervision across four marine centers in the North Sea region [3]. - Inspection teams traveled over 2000 kilometers, focusing on areas prone to sudden water increases, and verified the completion of 32 self-inspection items across five major categories [3]. Group 2: Technological Empowerment - The North Sea Bureau enhanced inter-departmental collaboration and upgraded the intelligent marine forecasting platform by adding new warning modules for sudden water increases, including sound and light alarms, SMS alerts, and phone notifications [5]. - The upgraded platform is operational across three levels of forecasting institutions and has been deployed in six coastal cities in Liaoning Province and Weihai City in Shandong, forming an intelligent defense chain for early detection and response [5]. Group 3: Emergency Response Training - The North Sea Bureau organized emergency drills simulating sudden water events, involving collaboration with marine disaster reduction departments from three provinces and one city to test the full process of warning issuance, information linkage, and emergency response [7]. - These practical exercises provided scientific and standardized guidelines for disaster prevention and reduction at the grassroots level, reinforcing the foundation for marine disaster defense during the flood season [7].
