Coastal Groundwater Salinity and Temperature: Prudhoe Bay, Alaska 2022

Field studies were conducted along the coastline of Simpson Lagoon near Prudhoe Bay, Alaska, to assess hydrological processes along an Arctic coastline. In July 2022, a transect of monitoring wells was installed and each of the five wells was equipped with a conductivity, temperature, and depth (CTD) logger to monitor water level, salinity, and temperature at fifteen-minute intervals in the subsurface. CTD loggers were also installed in the nearshore lagoon and pond adjacent to the tundra for continuous surface water measurements. Loggers were retrieved September 29, 2022.

This resource includes publication of the specific conductivity (uS/cm) and water temperature (degrees C) measurements to accompany the previously published water level data at Guimond (2023) and Guimond et al. (2023). This resource also includes publication of the pond water level, which has been corrected for barometric compensation and to the same datum as previous data publication.

为探究北极海岸线的水文过程，研究团队于阿拉斯加州普拉德霍湾附近的辛普森泻湖沿岸开展了野外实地考察。2022年7月，研究人员布设了一条监测井剖面，共安装5口监测井，每口井均配备电导率-温度-深度（Conductivity, Temperature, Depth, CTD）记录仪，以15分钟的采样间隔对地下水位、盐度及地下温度进行监测。同时，在近岸泻湖及毗邻苔原的池塘中也安装了CTD记录仪，以持续采集地表水监测数据。所有记录仪于2022年9月29日完成回收。

本数据集包含比电导率（单位：微西门子/厘米，μS/cm）与水温（单位：摄氏度，℃）的实测数据，以补充Guimond（2023）及Guimond等人（2023）已发表的水位数据。此外，本数据集还涵盖经气压校正、且与既往数据发布采用统一基准面的池塘水位数据。如需了解数据采集的更多细节，请查阅本数据集关联的研究论文与数据产品文档。
