Surface Sulphur Hexafluoride (SF6) values at start and finish of CTD casts from R/V Tangaroa cruise 61TG_3052 in the Southern Ocean in 1999 (SOIREE project)

SOIREE Surface SF6 Values at CTD Times<br><br>

<i><b>Comments preserved from the original file:</b><br>
This table gives the values of the underway SF6 at the<br>
start and finish times of each CTD down and up cast.<br><br>

A value of -1 indicates either that no SF6 data is<br>
available at that time, or that the closest measurements<br>
were separated by more than 15minutes, and so the data<br>could not be reliably interpolated.<br><br>

The percentage columns are the SF6 values expressed as a<br>
percentage of the maximum concentration during the previous<br>
evening's mapping.<br><br>

The upcast column is 0 for downcasts and 1 for upcasts.</i><br><br>

SOIREE 海表六氟化硫（SF6）CTD时刻观测值

【保留自原始文件的注释说明】：
本表格提供了每一次CTD（温盐深剖面仪）下行与上行剖面测量的起始及结束时刻对应的走航式六氟化硫（SF6）观测值。

取值为-1的情况分为两类：一是该时刻无可用的六氟化硫（SF6）观测数据；二是与该时刻最邻近的有效观测间隔超过15分钟，无法通过插值得到可靠的对应数值。

百分比列中的数值为六氟化硫（SF6）浓度相对于前一日夜间海况测绘期间测得的最高浓度的百分比占比。

上行剖面标识列中，下行剖面记为0，上行剖面记为1。
