Email:yjc@ Abstract—Underwater vehicles are mobile platforms with ex- cellent maneuverability, which are preferred for ocean obser- vation. Especially, the underwater glider with endurance of mouths and years, is suitable for ocean regional coverage sample and vertical profile sample. In this paper, we first describe the development of monitoring center with multi gliders for ocean observation in the South China Sea; and secondly, we give ocean feature tracking simulation and vertical profile optimal sample simulation; and lastly, we discuss the monitoring center utilization and glider experiments during 2014. I. INTRODUCTION Observation and monitor of ocean environment is the foun- dation of ocean scientific research, development and exploita- tion. And also, it is an important method for ocean climate prediction and forecasting. The traditional observational in- struments include the buoy, subsurface buoy, and science survey ship, which are utilized for ocean sample and ocean scientific research. The micro scale ocean dynamic processes, such as internal waves, thermocline, upwelling, are vulnerable influence by the external wind, ocean current, and atmosphere. These phenomena are typical physical ocean processes with high nonlinear in spatial and temporal scale. So it is difficult to observe them with the traditional methods. The technology development and application of underwater vehicles make it possible to track these ocean phenomena in a real time mode. Especially, underwater gliders with excellent controllability and long time endurance make the adaptive ocean observation possible. Th
