渤海辽东湾海域进入严重冰期

Core Viewpoint - The severe cold weather in Liaoning Province has led to significant ice formation in the Liaodong Bay, impacting various marine activities and infrastructure [1] Group 1: Weather Impact - Liaoning Province has experienced extreme cold, with temperatures dropping below -30 degrees Celsius in some areas [1] - The Liaodong Bay entered a severe ice period on January 19, with the maximum distance of floating ice from the shore reaching 58 nautical miles [1] - The total ice area in Liaodong Bay has reached 12,953 square kilometers, accounting for 42.33% of the bay's total area, which is heavier than the same period in the last decade [1] Group 2: Effects on Marine Activities - The ice conditions are expected to affect marine aquaculture, fishing ports, shipping, oil and gas production, and inhabited islands to varying degrees [1] - High-density thick ice may obstruct shipping lanes and ports, while ice drift poses risks to fishing vessels and aquaculture rafts [1] - Offshore oil platforms, wind power, and photovoltaic structures are at risk of collision and damage from floating ice [1] Group 3: Monitoring and Research Initiatives - The North Sea Bureau of the Ministry of Natural Resources has initiated a comprehensive survey of sea ice in the Bohai and Yellow Seas for the winter of 2026 [1] - The "Polar" icebreaker is heading to the core ice area of Liaodong Bay to conduct a comprehensive survey covering sea ice, meteorology, hydrology, and ecology [1] - A multi-dimensional sea ice observation network has been established, integrating marine stations, vessels, drones, video points, radar, and satellites [1]
