ABSTRACT:
A method of delivering to the ocean bottom and raising to the surface of a station provided with instrument packages for deep-water researches is realized by way of free submergence of the station in a water mass under the action of negative buoyancy of a ballast weight, landing of the station to the bottom, dropping of the ballast weight upon completing the bottom researches, and free emergence of the station under the action of positive buoyancy of a float module. In the course of free submergence, the station is divided into a unit comprising the instrument packages and a unit comprising the ballast weight and the float module, the unit comprising the instrument packages is directed along a path differing from the path of the free-falling unit comprising the ballast weight, thus ensuring the landing of the instrument packages at a predetermined distance from the ballast weight. After the ballast weight has been dropped the instrument packages are lifted off the ocean bottom with the float module attaining a constant ascending speed. A station for deep-water researches comprises a float module and a ballast weight connected therewith by means of a flexible link, a flexible link release controlled through a hydroacoustic channel, as well as instrument packages. The instrument packages are interconnected by means of a cantilever rod mounted on the float module for a free upward movement, fastened thereto by an elastic rope and provided with a means to create hydrodynamic resistance to the movement of the cantilever rod during submergence of the station.
