An equipment complex for deploying and recovering marine geophysical seismic or electric-survey bottom stations is mounted on a ship. The complex includes—a powered capstan, —rotatable turntables and rolls, —load-bearing units connected to the bottom stations by various fasten means and capable of winding onto the capstan and turntables, a work platform supporting a bottom station placed thereon, —an indicator for registration of the bottom stations' coordinates, mounted on the platform, —a limit switch mounted on the platform, switching ON when the bottom station is placed on the work platform, and OFF when it's removed therefrom providing for operation of the indicator. The complex may include floating buoys, damping loads, and halyards for deploying the stations. Methods for deploying and recovering the bottom stations using the equipment complex are described. Some recovering methods contemplate winding the load-bearing units onto the capstan, while switching the turntables for each subsequent load-bearing unit.
