Satellite trackings of surface drifters are widely used for direct measurements of ocean circulation at the surface layer. Trackings of the Mid-Depth floats are made made by using acoustic signals. An example of this technique is sofar floats. However, Tracking range is limited and it needs set and recomery of receiving stations.Development of Pop-Up float for free drift at Mid-Depth is achieved in this study. The float drift for several tens of say and it comes to the surface. During the surface drift for 25 houfs, It transmits fadio signals for the argos system. It descends again to the preset depth of drift which is determined before launch. The Pop-Up is achievid by gas generation in the float. Electrolysis of pure water is tested, Ad it is proved to be a successful method. Hydrogen gas generator is also developed in this study. Working mathrial is calcium hydrate contained in a capsule. A small and light argos transmitter of total weight of 45 G is obtained for the study. Completion of the Pop-Up Float will be made after sea trial ofthe gas generator in march 1991.

表层漂流物的卫星跟踪广泛用于直接测量表层海洋环流。中深度浮标的跟踪是通过使用声音信号进行的。这种技术的一个例子是到目前为止的浮动。但跟踪范围有限，需要接收站的设置和恢复。本研究实现了中深度自由漂的Pop-Up浮标的研制。浮子漂了几十次就浮出水面了。在表面漂移25 houfs期间，它为argos系统传输fadio信号。它再次下降到发射前确定的预设漂移深度。弹出是通过浮子中产生气体来实现的。对纯水电解进行了试验，证明这是一种成功的方法。本研究还开发了氢气发生器。工作物质是胶囊中含有的氢氧化钙。本次研究获得了总重量为45G的小型轻量argos发射机。弹出式浮标将于 1991 年 3 月气体发生器海试后完成。
