摘要
海洋沉积动力学研究中,底部边界层水流作用下的微地貌演变的长时间序列观测,需要采用针对性很强的专用水下相机.本文研制的水下相机系统,支持定时等时间间隔自动拍摄功能,具有续航时间长、水密性及防腐蚀性能好等方面的优势.台湾浅滩现场实验结果表明,该系统很好的完成了长时间序列微地貌动态过程的记录任务,为沉积动力学的研究提供了有效的数据支持.
In the study of the sedimentary dynamics,long time series records of the micro-geomorphologic evolution require the use of highly specific underwater camera.In this paper,an underwater camera system was designed for long time submarine observation.It has an automatic shooting function according to the pre-set time interval.Further,it is able to perform well in terms of water-tightness and anti-corrosiveness.In situ observations from the submarine dune field of the Taiwan Strait show that the system can fulfill the mission to record long time micro-geomorphologic evolution.The system provides an effective data support to further the study of the seabed morphologic dynamics.
