监测北太平洋海洋环流脉搏

国家重点基础研究发展计划（973计划）项目“北太平洋盂Ⅱ热带环流变异及其对我国近海动力环境的影响”借助中国海洋大学海洋综合调查船“东方红2号”，于2008年9月中下旬进行了深海大洋科学考察，在西太平洋黑潮源地和吕宋海峡成功布设潜标，形成了较完整的潜标观测阵列，并在东海陆架处布设海床基ADCP（acoustic doppler current profiler，声学多普勒水流剖面仪）测流系统。这标志着我们首次构建了由副热带北太平洋和我国边缘海所构成的大洋一边缘海动力系统的多点同步长期观测系统，为认识这一大洋一边缘海动力系统的能量物质交换提供了关键的观测支撑，同时也是我国深海大洋动力环境调查的一次重要探索，为我国深海大洋动力环境长期观测研究提供了宝贵的经验。

Monitoring Pulse of the North Pacific Ocean Circulation

The National Basic Research Program of China （973 program）, entitled “Low-frequency variability of the Subtropical North Pacific Ocean Circulation and its impacts on the dynamic environment of Chinese coastal seas” conducted a deep ocean scientific expedition in later half of September, 2008 with RV “Dongfanghong 2” of Ocean University of China. In this expedition, subsurface mooring arrays were deployed at the origin of the Kuroshio Current and in the Luzon Strait, as well as one low ADCP （Acoustic Doppler Current Profiler） on the East China Sea shelf north of Taiwan. This project, for the first time, set up a multipoint synchronous longterm observational system to monitor the deep oceanmarginal sea dynamic system composed by the Subtropical North Pacific Ocean and Chinese Coastal Seas. The system will provide a critical support for understanding processes and mechanisms of mass and energy exchanges in this deep ocean-marginal sea dynamic system. The implementation of the observation system is an important exploration of deep ocean dynamic environment in-situ investigation, and will provide valuable experience for future long-term in-situ investigation of deep ocean dynamic environment by our country.
