It is very important that we develop multi-dimensional sensing in combined with satellite remote sensing, underwater remote sensing and direct survey to predict when, where and how much are marine living resources available. Objectives of this study are to develop methodology of multi-dimensional sensing of marine living resources and their environment and to monitor three-dimensional distributions of Japanese common squid and three dimensional environment using acoustic with towed body transducer and real-time towing CTD system with satellite images. Major results are as follows :(1)Observation depth of real-time towing CTD system is from 10 meter to 80 meter in the condition of the length of wire of 300 meter and ship running speed of 10 knot.(2)Three-dimensional observation in the southeastern Bering Sea was successful to gather environmental structure and biomass of fishes using real-time towing CTD and acoustic system EK500. Visualization those three-dimensional distribution was established using AVS software.(3)In the First Oyashio intrusion region off Cape Erimo, three-dimensional fine structure was observed using real-time towing CTD system and acoustic system.

发展卫星遥感、水下遥感和直接调查相结合的多维遥感，对预测海洋生物资源何时、何地、有多少是十分重要的。本研究的目的是开发海洋生物资源及其环境的多维传感方法，并使用拖曳体换能器声学和实时拖曳CTD系统与卫星图像监测日本鱿鱼的三维分布和三维环境。主要研究结果如下：（1）在缆长为300 m、航速为10节的条件下，实时拖曳CTD系统的观测深度为10 ~ 80 m。（2）在白令海东南部进行了三维观测，利用实时拖曳CTD和声学系统EK 500，获得了白令海东南部的环境结构和鱼类生物量。利用AVS软件建立了三维分布的可视化模型。(3)In利用实时拖曳CTD系统和声学系统，对尾里摩角外的第一个Oyashio侵入区进行了三维精细结构观测。
