A new-version, cabin-style and trawl-resistant seabed based System is introduced. It can be deployed in regions with a water depth smaller than 200 m and used for continuous, long-term, multi-discipline observation.It is composed of the seabed platform, the floating body and the release device, and can carry multiple ocean monitoring sensors to carry out multidisciplinary observation. The method of deployment and recovery are also designed. Through in-situ experiments, this seabed based System shows advantages in auto measurement, concealment, and anti-trawling. It can be utilized for long-term, multi-discipline observations of marine environment.
