The purpose of this research was to develop a new high-resolution altimeter for monitoring of distance between the camera system and sea bottom. Also, a feasibility study was conducted for the development of super deep real-time video system for the research of deep-sea trenches.The altimeter which uses 50kHz echo sounder for depth monitoring was successful for detection of distance between camera and seafloor. The accuracy was 5% of the distance. Then this altimeter was deployed on a new deep sea video-camera system, DESMOS which were developed at Ocean Research Institute, Univ. Of Tokyo for the use on R/V Hakuho-maru. A successful trial at the Manus Basin in the Bismark sea indicates that an initial concept of 6000m class deep water system was proved to be feasible. A further consideration was given to design of 10,000 m class video-camera system. The most severe technological difficulty is related to design of the cable. At present, we assess the system should be composed of launcher and secondary vehicle. However, the system can well be too gigantic to be operationally feasible.

本研究的目的是发展一种新的高分辨率高度计，用于监测相机系统与海底之间的距离。同时，还对开发用于深海沟研究的超深实时视频系统进行了可行性研究，成功研制了使用50 kHz回声测深仪进行深度监测的高度计，用于探测摄像机与海底的距离。准确度为距离的5%。然后将该高度计安装在东京大学海洋研究所开发的新型深海摄像系统DESMOS上，用于R/V Hakuho-Maru。在俾斯麦海马努斯盆地的一次成功试验表明，6000米级深水系统的初步概念被证明是可行的。进一步考虑设计10，000 m级摄像机系统。最严重的技术困难与电缆的设计有关。目前，我们评估该系统应该由发射器和辅助运载工具组成。然而，该系统可能过于庞大，在操作上不可行。
