PROBLEM TO BE SOLVED: To provide a method for detecting the flow state of oceanic layers and capable of grasping behaviors of a discharged liquid even in an oceanic intermediate layer. SOLUTION: Both an ocean towed body 4 to be towed by a ship 1 navigating on the ocean and a wire 11 for maintaining a data carrier 12 in an oceanic layer of a prescribed depth are provided. The state of diffusion of a fluorescent dye discharged is predicted on the basis of behaviors of a buoy 102 and tracked by adjusting the course of the ship. Tracking information is transmitted to the ship 1 via the ocean towed body 4 to grasp a distribution and behaviors of diffusion of the fluorescent dye and derive the flow state of the prescribed oceanic layer. It is thereby possible to derive the flow state of the oceanic layer of the prescribed depth. COPYRIGHT: (C)2007,JPO&INPIT
