ASPIRE station data used to develop 1-D and 3-D numerical models from the Nathaniel B. Palmer in the Amundsen Sea from 2010-12-14 through 2011-01-05

<p>Hydrographic profiles and discrete water samples were collected from each station using a conventional shipboard conductivity-temperature-depth (CTD; Sea-Bird 911+) sensor and a 24 × 10 L Niskin bottle rosette sampler (General Oceanics). Potential temperature (θ) and salinity (S) were recorded continuously as a function of depth and at the moment of Niskin bottle closure (see Yager et al., 2016).</p> <p>Trace-metal samples were collected similarly using a trace-metal-clean CTD-rosette system (see Sherrell et al., 2015) that was deployed at the same location just before or after the conventional CTD.&nbsp;</p>研究人员使用传统船载电导-温度-深度（conductivity-temperature-depth，CTD；Sea-Bird 911+）传感器与24×10升尼斯金采水瓶组采样器（General Oceanics公司制造），从各站位采集了水文剖面数据与离散水样。位温（θ）与盐度（S）会随深度连续记录，同时在尼斯金采水瓶关闭瞬间同步获取观测数据（详见Yager等，2016）。 痕量金属样品的采集流程与之类似，采用痕量金属清洁型CTD-采水器系统（详见Sherrell等，2015），该系统会在传统CTD部署的前后，于同一站位完成投放。
