Abstract:

Direct measurements of bulk density and penetration resistance, and indirect measurements of shear strength and water content in the Wilkinson and Murray Basins were made using the small submersible Alvin in July 1971. A probe consisting of a nuclear transmission densitometer and a static cone penetrometer was adapted for use on the submersible. A total of 10 test penetrations in 240-247 m water depths were made during three dives. The Alvin investigations showed that a small submersible is capable of developing the reaction force needed to penetrate a relatively large probe greater than 1 m in soft clay.
