Temperature, Salinity, Depth data in the Kara Gates Strait in July 2023, Arctic Ocean

Oceanographic data were collected in the Kara Gates Strait during the "Floating University 2023" cruise onboard the R/V Dalnie Zelentsy from 17 to 20 July 2023. A total of 47 full-depth Conductivity-Temperature-Depth (CTD) casts were performed across the strait at depths ranging from 30 to 200 m using a Sea & Sun Technology CTD 48M probe. Furthermore, a drift station was occupied to obtain high-frequency temperature data. A 45-meter-long distributed temperature sensor string (thermal profiler; see Svergun et al., 2022, https://doi.org/10.37102/1992-4429_2022_42_04_05 for instrument details) was deployed. During this drift, repeated yoyo CTD casts were also conducted. This dataset is suitable for analyzing the vertical thermohaline structure to study internal wave dynamics and frontal processes in the region.

本数据集采集于2023年7月17日至20日期间，搭载“达尔尼·泽连茨号”科考船（R/V Dalnie Zelentsy）执行的“流动大学2023”航次，观测海域为卡拉盖茨海峡（Kara Gates Strait）。本次航次共完成47组全深度电导率-温度-深度（Conductivity-Temperature-Depth, CTD）剖面测量，采用Sea & Sun Technology公司生产的CTD 48M型探头，测量覆盖水深范围为30米至200米，测线横跨该海峡。此外，还布设了漂移观测站位以获取高频温度数据，并部署了一套总长45米的分布式温度传感器串（热剖面仪，仪器细节参见Svergun等，2022，https://doi.org/10.37102/1992-4429_2022_42_04_05）。在该漂移观测期间，同步开展了重复升降式CTD剖面测量。本数据集可用于分析该区域的垂向温盐结构，以研究其内波动力学与锋面过程。
