<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>OOI-CGSN 温盐深（Conductivity, Temperature, Depth, CTD）采样指南</strong></p>
<p>通常而言，水样采集的深度需与原位测量仪器的部署深度相匹配。例如，近地表仪器架（Near Surface Instrument Frames, NSIFs）搭载的仪器可测量溶解氧（dissolved oxygen, DO）、盐度、硝酸盐（NUTNR）、二氧化碳分压（CO₂）以及叶绿素a荧光，因此需在该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选取需服务于更广泛的科学研究问题。</p>
<p>静置平衡时间——需根据现场条件，将CTD采水器架在目标深度处静置平衡至少1分钟，直至CTD传感器读数稳定。若需进行声学释放测试或其他作业，可延长静置平衡时间。</p>
