A New Achievement of Soviet Marine Geology (The Sysoyev-Kudinov Hydrostatic Coresampler)

摘要

This device consists of a steel cylinder designed to stand considerable pressure, a valve mechanism, and the core tube. The valve mechanism closes the tank off before the apparatus is lowered away, and opens it automatically when the tube touches sea bottom. The core tube is in sections and thus may be of different lengths, according to the task in hand and the operating conditions. The inside diameter of the tube is 60 mm. Assembly of the tube and its lowering are handled by means of a special auxiliary device, and outboard rack along the ship's side. The chief merit of the sampler is claimed to be its ability to take cores of considerable length with an excellent quality of the soil sample.
