Engineering properties of sediments in the vicinity of Guide Seamount.

MetadataShow full item record
The sophisticated vane shear apparatus for determining the shear strength of deep ocean sediment cores was modified so as to be portable and versatile for use In a laboratory and on board a ship. The apparatus utilizes a torque transducer that is insensitive to temperature changes or orientation and capable of measuring torque over the entire range of shear strength encountered in marine sediments. Shear strength measurements can be made with minimum disturbance to the sediment sample by testing directly in the core liner. The apparatus was used to determine shear strength of ten deep ocean cores from the Guide Seamount region, located about 70 miles west of the central California coast. The study also included the determination of other engineering properties of the sediment cores.
