III. Development of ecosystem-monitoring tecnique

@Mid- and deep-sea (150?2000 m depth) ecosystems include various organisms, such as myctophid fish and jellyfish. State-of-the-art ocean observation techniques with acoustic and visual instruments are applied to such marine ecosystems and real-time data can be transferred using internet accesses and satellite communications. Development of such monitoring technique will provide a real-time analysis of oceanographic conditions and biological information.

(1)  Development of measuring system for jellyfish by Visual Plankton Recorder (VPR)

(2)   Development of acoustic survey for mid- and deep-sea fish biomass

(3)   Development of real-time data transfer system connecting laboratories and research vessels
