ooze samples from near the sediment surface must be made on-board 

 ship immediately after obtaining the sample. 



Bulk Density 



In the laboratory, the measured total bulk densities of the 

 two box corer samples were 1,470 and 1,471 kg/m-^ (91.7 and 91.8 

 pcf). Using these final bulk densities and using the sample settlements 

 measured in the core boxes, the initial total bulk densities, at 

 time of trimming on the WILKES, were backfigured to be 1,454 and 1,460 

 kg/m (90,8 and 91.1 pcf). 



Water Content 



Water content measurements made before and after transport 

 are presented in Figures 7 and 8. These values represent the mass 

 lost during drying at 105 C divided by the mass remaining [29]. 

 Correction for salt content has not been made [30], Such correction 

 will raise the calculated water content by 5 to 6%. For example, 

 an uncorrected water content of 87.5% is equivalent to a corrected 

 value of 92.5%. Some variation between the two curves of each figure 

 should be expected because the two curves represent data from different 

 box corer samples, probably separated by several hundred meters 

 distance. However, the change in water content, from the initial 

 state immediately after sampling to the end state at the end of 

 transport, is so marked as to overshadow initial inter-sample differences. 

 An overall reduction in water content is indicated with lesser 

 reductions at the very top and bottom of the box cores. The data 

 of Figure 7, suggesting that the very bottom of the box core increased 

 in water content during transport, may not represent a true water 

 content change during transport. A facies change to coarse shell 

 material occurred at this depth, and the small water content samples 

 may not represent the average properly. 



Vane Shear Index 



Vane shear measurements were run in the laboratory on the top and one 

 side of box corer sample 4 (Figures 9 and 10). The trend of the 

 strength and sensitivity measurements does not correspond ideally 

 to what one would expect from the water content data in that, for 

 the depth interval from to 75 mm, the vane shear strength decreases 

 with a decrease in sample water content. This variation is believed 

 due to variation of material with depth rather than to differential 

 cementation or disturbance.
