ABSTRACT OF THE DISCLOSURE The present invention relates to the self-contained tech- nical means and may be advantageously used for carrying out geological, hydrographic and oceanological works. An apparatus for taking bedrock samples from the bottom of deep-water basins comprises a float with a rod and support- ing frame, containers with ballast weights and a working member. A casing of the working member is made split with an open bottom. Disposed inside the working member casing is a shell destroyed when acted upon by an initiating device at the moment the work- ing member gets in contact with the bottom of a water basin, and a device for catching and holding a sample. The initiating device is installed in the upper part of the working member and provided with a release mechanism operatively associated with a device for dropping ballast weights. The upper part of the working member casing is provided with a thrower. The lower part of the working member casing is provided with a packing ring. The device for dropping ballast weights is located in the middle part of the supporting frame coinciding with the float rod provided with pin-type catches cooperating with flex- ible links fixing the ballast weights.
