Water temperature, salinity, and currents collected from subsurface moorings deployed by the research vessel Sanna and taken by CTD and ADCP along the ship track in the Uummannaq Bay, west Greenland, from 2013-09-12 to 2015-07-22 (NCEI Accession 0173969)

This data set contains temperature, salinity, and pressure observations from seven subsurface moorings placed in the Uummannaq Bay, west Greenland. The purpose was to quantify heat transport and water mass variability near the tidewater glaciers in this area. Some of the sensors were damaged by iceberg strikes, and fell towards the bottom (they were on a weak link). This dataset also contains water-column profiles of salinity and temperature collected using a conductivity/temperature/depth (CTD) sensor and water-column velocity data collected using a vessel-mounted acoustic Doppler current profiler (ADCP) collected only in 2014. CTD data were collected throughout the fjords of Uummannaq Bay from the R/V Sanna (Greenland Institute of Natural Resources vessel) using an RBR profiling CTD throughout the project period. ADCP data were collected using an RDI 300 kHz ADCP during during certain CTD transects only from the R/V Sanna during summer 2014. The ADCP was pole-mounted off the side of the vessel with an integrated Hemisphere GPS receiver. Data were subsampled to 15-minute intervals. The data file format is NetCDF.

本数据集收录了位于西格陵兰乌穆纳纳克湾七个海底浮标所采集的温度、盐度和压力观测数据。其目的在于量化该区域潮汐冰川附近的热传输和水质参数的变异性。部分传感器因冰山撞击而损坏，沉降至底部（它们位于薄弱环节）。此外，该数据集还包含了使用电导率/温度/深度（CTD）传感器收集的水柱盐度与温度剖面，以及2014年使用船载声学多普勒流速仪（ADCP）收集的水柱流速数据。CTD数据在项目期间由“Sanna”号（格陵兰自然资源研究所船只）在乌穆纳纳克湾的峡湾中进行收集，使用RBR剖面CTD。ADCP数据仅在2014年夏季的某些CTD横断面中使用“Sanna”号，并配备有集成半球GPS接收器的ADCP安装在船侧。数据经过下采样，以15分钟为间隔。数据文件格式为NetCDF。
