OOI Global Southern Ocean Array CTD and Discrete Water Sampling Data from Mooring Overturning Cruises in the Southern Pacific Ocean from 2015-2020 (OOI Cruise Data project)

<p><strong>OOI-CGSN CTD Sampling Guidelines</strong></p> <p>In general, water samples are collected for analysis at depths that correspond to instrumentation making in situ measurements.&nbsp; For example, Near Surface Instrument Frames (NSIFs) have instrumentation that measure dissolved oxygen (DO), salinity (CTD), nitrate (NUTNR), the partial pressure of CO₂&nbsp;(CO₂), and chlorophyll a fluorescence, so water samples should be collected at the depth of the NSIF for analyses of all those parameters.&nbsp; Additionally, as noted above, OOI water sampling data are valid long-term datasets in and of themselves. Thus, some measurement locations are driven by broader science questions.</p> <p>Soak Time –&nbsp;The CTD rosette should be allowed to equilibrate (e.g., the CTD sensor readout stabilizes) at the desired target depth for at least 1 minute or more depending on conditions.&nbsp; Longer soak times may occur to accommodate acoustic release testing or other activities.</p> <p><strong>Citing OOI Data</strong></p> <p>Refer to specific guidance related to citing&nbsp;OOI data on the OOI website at https://oceanobservatories.org/how-to-use-acknowledge-and-cite-data/.&nbsp;</p><p><strong>OOI-CGSN 温盐深（CTD）采样指南</strong></p> <p>总体而言，水样采集的深度应与开展原位测量的仪器部署深度相匹配。例如，近地表仪器架（Near Surface Instrument Frames, 简称NSIFs）搭载的仪器可测量溶解氧（Dissolved Oxygen, 简称DO）、盐度（CTD）、硝酸盐（NUTNR）、二氧化碳分压（CO₂）以及叶绿素a荧光，因此需在近地表仪器架的部署深度处采集水样，以完成上述所有参数的分析。此外如前文所述，OOI的水样采集数据本身即为可靠的长期数据集，因此部分测量点位的设定需兼顾更广泛的科学研究问题。</p> <p>静置时长（Soak Time）——需将CTD采水罗塞塔架在目标采集深度下充分平衡（例如CTD传感器读数趋于稳定），静置时长根据现场条件至少为1分钟及以上。若需开展声学释放测试或其他作业，可适当延长静置时长。</p> <p><strong>OOI数据引用规范</strong></p> <p>有关OOI数据的引用细则，请参阅OOI官方网站发布的相关指南：https://oceanobservatories.org/how-to-use-acknowledge-and-cite-data/。</p>
