Acoustic Profile Dataset Obtained through the 9th Chinese Arctic Expedition

海洋声学剖面数据是了解海洋物理特性、提高水下目标检测和定位精度、优化水下通信网络设计的关键数据集，也是监测海洋环境变化的重要指标。直接观测海洋声学剖面不受模型预测或估计误差的影响，提供精确的声学剖面数据。这些数据对科学研究、技术开发、环境监测、资源开发和实际应用具有重要价值。在 2018 年夏天进行的第 9 次中国北极科学考察期间，首次使用声学多普勒洋流剖面仪直接观测海洋中的声速。在楚科奇高原、加拿大盆地、北冰洋门捷列夫海脊和其他高纬度海域获得了海洋声学剖面的第一手测量数据。本文基于中国第九次北极考察期间对声学剖面仪和同步 CTD 数据的收集和组织，参考航行的现场记录，并使用相关数据处理软件对实测海洋声学剖面数据进行统一、标准化和去除异常值。最终，形成一个垂直分辨率约为 1 m 的数据集，包括日期、时间、声速和水深等元素。它是 9 的输出结果th

Marine acoustic profile data is a pivotal dataset for comprehending marine physical properties, enhancing the accuracy of underwater target detection and localization, optimizing the design of underwater communication networks, and serving as a critical indicator for monitoring marine environmental changes. Directly observed marine acoustic profiles are unaffected by errors from model predictions or estimations, providing precise acoustic profile data. This dataset holds substantial value for scientific research, technological development, environmental monitoring, resource exploitation, and practical applications. During the summer of 2018, in the 9th Chinese National Arctic Research Expedition, acoustic Doppler current profilers (ADCPs) were used for the first time to directly measure the sound speed in the ocean. First-hand measured marine acoustic profile data were obtained in the Chukchi Plateau, Canada Basin, Mendeleev Ridge of the Arctic Ocean, and other high-latitude sea areas. This study is based on the collection and organization of acoustic profiler and synchronous CTD data during the 9th Chinese National Arctic Research Expedition, with reference to on-site voyage records, and uses relevant data processing software to unify, standardize and remove outliers from the in-situ measured marine acoustic profile data. Ultimately, a dataset with a vertical resolution of approximately 1 m was formed, including parameters such as date, time, sound speed and water depth. It is one of the outcomes of the 9th Chinese National Arctic Research Expedition
