The samples are rectangular in shape, 8x12 inches in plan and a maximum of 18 inches high. Good cores have been obtained from clayey material as well as from gravelly sand. No disturbances due to coring were observed on the collected samples. These large samples make it possible to conduct many varieties of investigations, such as study of living organisms and shear strength measurements, as soon as the sample is on deck of a ship; radiography of slices, peeling and impregnation techniques, granulometry, mineralogy, porosity, fossil contents, etc. Construction and use of the box core and applications of some of these analytical techniques are described." Purpose: Samples were collected as trials for the sampler. Supplemental_Information: Data are included in the Deck41 compilation held at NGDC; samples in that compilation have been decommissioned in usSEABED.
