Abstract—In 2019, a new instrument was included in the multifunctional measuring complex at the Gelendzhik Research Site (Shirshov Institute of Oceanology, Russian Academy of Sciences, IO RAS), which allows automatic measurement of the hydrophysical parameters of the aquatic environment from the bottom layer to the surface of the waterbody with on-line transfer of data to the coastal center. This is a stationary station that uses a bottom winch for automatic vertical profiling of natural waterbodies. The model of the station was developed in 2018. It measures temperature profiles with temperature and pressure sensors located in a streamlined body: a carrier that moves according to a programmed algorithm. The carrier has positive buoyancy and is connected by a thin strong coaxial cable to the station’s bottom unit. The bottom unit includes a winch and electronic control units. The cable provides power to the carrier sensors and transmission and recording of measurement data in the station’s solid-state memory. Parameter measurements with a fine-structure vertical resolution are carried out with probes moving up and down. The data obtained are transmitted via a fiber-optic cable laid along the sea bottom to the coastal center located at the end of the pier of the Southern Branch of IO RAS. This cable also supplies the station with power. The first results demonstrated the qualitatively new possibilities of the station for measuring the parameters of the marine environment in the entire water column, including the near-surface layer.
