| 摘 要： | 对3次海上调查的CTD溶解氧观测资料与现场同步实验室测定的溶解氧资料进行了对比分析，反映了CTD仪器溶解氧传感器从开始使用到溶解氧膜失效整个过程观测数据漂移的变化趋势。证明溶解氧传感器中溶解氧膜6～9个月的使用有效期限，并给出了如何用现场实验室测定的溶解氧数据(Labox)对CTD观测的溶解氧数据(CTDox)进行溶解氧偏差(Diffox)校正的方法。为今后海洋调查中取得真实可信的溶解氧资料提供技术指导。 |

| Abstract: | The comparative analyses of the dissolved oxygen data observed by CTD system and the dissolved oxygen data determined by on-site lab during 3 cruises were made to show the variation trends of observed data drift in the whole process from the initial use to the dissolved oxygen coat failure of CTD (oxygen) sensor.It is concluded from the analysis results that the valid period for using the dissolved oxygen coat is 6 to 9 months,and the methods for correcting CTD observed dissolved oxygen data with on-site lab determined dissolved oxygen data are proposed,which provides technical advices for obtaining correct and reliable dissolved oxygen data in the future oceanographic surveys. |
| Keywords: | CTD observed dissolved oxygen data lab determined dissolved oxygen data dissolved oxygen difference |
