<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. For example, Near Surface Instrument Frames (NSIFs) have instrumentation that measure dissolved oxygen (DO), salinity (CTD), nitrate (NUTNR), the partial pressure of CO<sub>2</sub> (CO<sub>2</sub>), and chlorophyll a fluorescence, so water samples should be collected at the depth of the NSIF for analyses of all those parameters. 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 – 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. 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 OOI data on the OOI website at https://oceanobservatories.org/how-to-use-acknowledge-and-cite-data/. </p>
<p><strong>OOI-CGSN CTD采样指南</strong></p> <p>总体而言，水样采集深度应与原位测量仪器的布设深度相对应，以用于后续分析。例如，近海面仪器框架（Near Surface Instrument Frame，NSIF）配备有测量溶解氧（DO）、盐度（CTD）、硝酸盐（NUTNR）、二氧化碳分压（CO₂）及叶绿素a荧光的仪器，因此需在NSIF所在深度采集水样，以分析上述所有参数。此外，如前文所述，OOI水样采集数据本身即为有效的长期数据集，故部分测量点位的设置需以更宏观的科学问题为导向。</p> <p>浸泡时间——CTD采水器（rosette）应在目标深度平衡至少1分钟（例如，CTD传感器读数稳定），具体时长视条件而定。若需进行声学释放测试或其他活动，浸泡时间可适当延长。</p> <p><strong>引用OOI数据</strong></p> <p>关于OOI数据的引用，请参考OOI官网的具体指南：https://oceanobservatories.org/how-to-use-acknowledge-and-cite-data/。</p>
