Summary: The results from these sediments, in particular the consolidation test results, appear inconsistent with the known geological history of the area. The consolidation test results are substantiated by both the anomalous relationships occurring between index properties (i.e. grain size increases as void ratio increases) and the shear-strength results. A number of possibilities are presented to explain these observations, including core disturbance, particle cementation, formation of bonded clay aggregates, and inadequate techniques for determining the preconsolidation stress. Available information precludes definitive conclusions as to which is most significant, although it is likely that each process has influenced the results to some degree. The results do show conclusively that conventional geotechnical relationships developed largely from terrestrial studies should not be applied to the marine environment without very careful consideration and analysis.
