Oceanography Measurement of shear strength was made by either of two methods: the laboratory vane shear or the unconfined compression test. The vane shear technique provides a rather simple yet suitable test for the relatively soft sub- marine sediments. In some instances, it was the only test that could be used be- cause of the very low shear strengths encountered. This test is made by inserting a small four-bladed vane into the sample and applying an increasing torque until a shear occurs (Evans and Sherratt, 1948; Richards, 1961). Unconfined compression tests were made on many of the more cohesive sam- ples. The test procedure is similar in principle to the standard test described in various soil mechanics texts, however, both the equipment and procedure were modified slightly to accommodate the relatively weak submarine sediments (Richards, 1961). For the purpose of this study, the sediments were considered to. I'ig. 3 38.
