LABORATORY TESTS 



The core samples were subjected to standard index property tests 

 (water content, sieve analysis, hydrometer, Atterberg limits, grain 

 density, and carbonate content), miniature vane shear tests, 

 consolidated-undrained triaxial tests with pore pressure measurements, 

 and residual pore water pressure tests. Standard CEL procedures were 

 followed as described in earlier reports (Lee, 1973a and 1973b). Some 

 difficulties were encountered, however, because the sediments from Sites 

 III and IV were nearly or completely cohesionless. Atterberg limits 

 tests could not be performed; the samples retained no negative residual 

 pore water pressures, and most of the specimens could not be trimmed for 

 triaxial testing in the usual manner. The samples that could not be 

 trimmed were remolded and placed in a triaxial specimen former. An 

 attempt was made to place the sediment at its original density.
