| After the four years of development of the modern maximum depth submersible, JAMSTEC has successfully completed the training dives of "SHINKAI 6500", a new manned submersible whose maximum operating depth is 6,500 meters, from June to October in this year. "SHINKAI 6500" was constructed by Kobe Shipyard and Machinary Works of Mitsubishi Heavy Industries Ltd. (MHI) and marked 6,465m and 6,527m dives in the Japan Trench during the sea trials with the support "YOKOSUKA" (built by Kawasaki Heavy Industries Ltd.) in August 1989. This paper presents the results of the sea trials, training dives and the features of "SHINKAI 6500" with her supporting technologies. |

| With the advent of deep submergence research vessels (DSRVs) biological and ecological studies of ocean deeps have made great strides. Especially these submersibles allowed to conduct physiological and biochemical experiments on benthic fauna directly on the bottom or on board with alive retrieved animals. A second great interest is the possibility to work in chaotic areas and on microenvironments. Without DSRVs most of measurements and observations obtained on hydrothermals vents would had been impossible. We will present the different equipment designed for the two French DSRVs used during the cruises conducted by the Departement "Environnement Profond" de l'IFREMER to study hydrothermal and "normal" deep-sea ecosystems. We will discuss the new devices... |

| The gelatinous macroplanktonic organisms living in the deep sea can only be studied with manned submersibles. There is presently in increasing interest in the study of the role of this part of the pelagic ecosystem, because they are strongly involved in the transformation of the particulate organic matter. Their transparency, small size and mobility present technical challenges, unanticipated by the designers of the first submersibles, aimed at the sea bottom observation. Despite these limitations, the use of conventional submersibles has brought very interesting results. It is hoped that engineers will take into account the requirements of pelagic observations in the design of future submersibles. |
