| 摘 要： | 自1995年“雪龙”号安装了可在走航时测定海水流速、流向的船载ADCP起,我国极地科学考察已经积累了丰富的走航ADCP资料。从极地科考走航ADCP资料中准确地提取海流信息,对南大洋以及南极毗邻海域的海流研究具有十分重要的现实意义。通过对影响海流信息提取的干扰因素分析,本文给出了针对极地科学考察船载ADCP资料处理的解决思路。只有在数据质量检查的基础上,时间一致性调整和船首向罗盘角度调整后,通过剔除船速信息才能准确地提取出海流信息。

| Abstract: | Abundant under-way velocity data in polar scientific expeditions of China have been accumulated ever since ice-breaker "Xuelong" was mounted the Shipboard-ADCP. It is very important for ocean current study in the Southern Ocean and adjacent sea area of Antarctica to derive current information from under-way ADCP data. Based on disturbance factor analysis,the approach of data processing of Shipboard-ADCP in polar scientific expeditions of China is presented.Several steps are vital for data processing and they are data quality examination,adjustment of time consistency,emendation of ship heading,ship speed elimination.The current data can be achieved only after these steps are accomplished well and truly. |
