极区冰下海洋自动剖面观测系统及其应用

Introduction and Application of An Automatic Profiler for Observing Ice Covered Polar Ocean

中国第25次南极考察期间,于2008年12月,首次将国内研制的冰下海洋自动剖面观测系统用于南大洋考察,在普里兹湾沿岸海冰上开展冰下海洋观测,获得了连续数日的冰下上层海洋温盐剖面数据,为研究浮冰区次表层暖水提供了连续现场观测资料。文中简单介绍了自动剖面系统的技术特点和布放方法以及在南极海域的应用,为以后开展极区冰下海洋观测项目提供参考。

A newly-developed automatic profiler was applied for observing the ice covered ocean during the 25th Chinese National Antarctic Research Expedition in December,2008.The profiler was mounted on fast ice in the Prydz Bay and recorded temperature and salinity data of the upper ocean continuously in several days.The data were used to study the sub-surface warm water in the ice covered ocean.The design and deployment in the polar region of the profiler are introduced in order to present reference for the future observations in the polar ocean.
