Field observation data in the Yangtze Estuary during Typhoon Muifa@en

The data includes pressure, sea pressure, and depth information of surface elevation. Field measurements have been collected from September 8th, 18:00, to September 15th, 18:00, for a total of 7 days in 2022 (China Standard Time, UTC+8). The study area is situated in Chongming Island, Shanghai. This region serves as a typical estuarine wetland in the Yangtze River Estuary. We set three observation points (121°56'12.988″E, 31°27'20.69''N; 121°56'2.5″E, 31°27'32.15''N; 121°56'.760″E, 31°27'33.95''N). During the observation period, from September 12th, 18:00, to September 15th, 18:00 2022, the hydrodynamics at the measuring points were affected by Typhoon Muifa. Chongming Island assumes a paramount role in safeguarding the ecological and environmental stability of the Yangtze River Delta region. Nevertheless, the island faces vulnerabilities, particularly in the face of natural disasters such as typhoon-induced storm surges during the summer season. A comprehensive examination of the typhoon events on the wave evolution within coastal wetlands holds substantial relevance. The implications of this research extend beyond localized defence strategies, with broader implications for the domain of coastal science and resilience, as it contributes to our understanding of the complex interplay between natural forces and coastal ecosystems.

本数据集涵盖气压、海水压力以及海面高程的深度测量数据。本次野外实测数据采集时段为2022年9月8日18:00至9月15日18:00，共计7天，采用北京时间（UTC+8）。研究区域位于上海市崇明岛，该区域为长江河口典型的滨海湿地。本次研究共设置3个观测点位，坐标分别为：121°56′12.988″E，31°27′20.69″N；121°56′2.5″E，31°27′32.15″N；121°56′0.760″E，31°27′33.95″N。在观测时段内，即2022年9月12日18:00至9月15日18:00期间，各观测点位的水动力环境受到台风“梅花（Typhoon Muifa）”的影响。崇明岛在维护长江三角洲区域的生态环境稳定方面发挥着至关重要的作用，但该岛生态系统仍存在脆弱性，尤其在夏季易受台风引发的风暴潮等自然灾害影响。全面探究台风事件对滨海湿地波浪演化过程的影响具有重要的科学意义。本研究的价值不仅局限于区域防灾策略，更为海岸科学与海岸韧性研究领域提供了新的认知，有助于深化对自然作用力与海岸生态系统间复杂相互作用机制的理解。
