Última Jamstec/deep tow camera system (on the manned submersible "SHINKAI 2000 vehicle") ArchiMer Otsuka, K. The JAMSTEC/Deep Tow Camera System conducts pre-site-surveys for the manned submersible "SHINKAI 2000". The vehicle is towed by double armored coaxial cable (RG-8/U) of 4500 m length. The color composite video signal is converted to an FM signal with central frequency of 6.15 MHz because it is very difficult to compensate completely for the transmission loss of video frequency through the coaxial cable. The data from the CTD sensors and the altimeter are displayed with date and time on the monitor screen in real time. Temperature data has proved very important in finding hydrothermal anomaly phenomena. Two years ago, our research group found an active chimney at North Fiji Basin during cooperative cruise between France and Japan. Last year, we deployed...
