The marine litter should be regarded as a major point of marine pollution that destroys the ecological and economic value of marine ecosystem and its components. Especially, the problem caused by the derelict fishing nets called "ghost fishing". In order to solve the problems raised by the marine liters, we have developed a practical and efficient survey system for sea bottom fishing nets. The apparatus consists of a guide frame, three deep-sea cameras for 1,000m water depth, buoys for keeping balance of survey system, a position tracking device, etc. The underwater survey system has a guarantee the survey of 7 meter range in width, and it is connected by high tension wire to surface ship such as towed type. The present paper shows the results on the development of an equipment to survey the marine litter, especially, such as fishing net, efficiently and practically at the bottom of deep sea, East Sea, Korea. The system was tested in in-situ test has been carry out to evaluate the efficiency and practical application of the system in 1,000m in depth. It is regard that the developed system will be available for sea-bed research such as deep ocean organism and geological survey.
