Marine Life Monitoring System

Non-invasive marine life monitoring system combining an open frame with an underwater camera

This technology is a marine life monitoring system that uses a structure combining an upper frame equipped with a camera and an open lower frame. It can be attached to underwater drones or installed in a fixed position to collect ecological data in a non-invasive manner.

Conventional ecological survey methods using divers or underwater robots often disturb the target species and face challenges in maintaining stable, long-term monitoring from a fixed location.

This technology proposes a design that houses an underwater camera and battery within an aluminum or STS316 pressure-resistant enclosure, mounted inside a fixed frame with an open structure that allows marine life to move in and out freely. This enables long-term monitoring without disturbing the organisms, while simultaneously performing underwater noise measurement, sonar detection, and water quality analysis. It is applicable to aquaculture management, marine ecological surveys, and fishery resource monitoring, providing a practical solution for research and industrial sites that require long-term data collection without disturbing marine life.

Key Features:

• Upper frame consisting of first upper and lower horizontal frames, a first central frame, and a plurality of first vertical frames
• Underwater camera unit included in the upper frame, with the camera lens facing downward and configured for underwater drone installation
• Lower frame coupled to the upper frame and positioned below it, consisting of second upper and lower horizontal frames
• Frame structure configured in an open form to allow marine life to enter and exit freely
