Abstract: The apparatus for taking bedrock samples from the bottom of deep-water basins includes a self-contained device for obtaining spot samples of bedrock from the bottom of deep-water basins and more particularly to devices for taking bedrock samples from the bottom of deep-water basins.The apparatus for taking bedrock samples from the bottom of deep-water basins is provided with a working member made in the form of a split housing having an open bottom and accommodating a shell to be destroyed by an initiating device at the moment the working member comes in contact with the bottom of a water basin, and a device for catching and holding a sample.

Abstract: The arrangement is mainly designed for transporting solid minerals from the floor of the ocean to a support vessel. The arrangement comprises an endless flexible carrier which is made of interconnected container sections. Each section has two chambers -- a load chamber and a float chamber. The arrangement also has means for batched loading of the chambers with solid mineral and compressed gas. During operation of the arrangement, the load chambers are loaded with solid mineral and the float chambers are filled with gas so that the loaded sections of the carrier acquire a positive buoyancy thus enabling displacement of the entire carrier.

Abstract: The device comprises a housing made in the form of a polygon having hinged sides. Installed in close proximity to housing, supports are tanks connected with fluid sources and producing positive and negative buoyancies in the region of the housing near the supports. To rotate the supports use is made of a means for varying the angles between the housing sides.
