| Research Abstract |
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.
