the core nose or core cutter; 





where Co is the outside clearance ratio that controls outside friction, Dw is the max?- 

 imum outside diameter of the core nose, and Df Ss the outside diameter of the core 



r = w " e ^j Volume of displaced sediment * 



_ 2 volume of the sample 



where C a is the area or Kerf ratio. These ratios, shown in Table \ t are significant , 

 and their application to the cores coliected in this program has been discussed in 

 part one, where it was concluded that all cores are, strictly speaking, disturbed 

 samples; those obtained with the Hydroplasfic corer appear to be among the least 

 disturbed „
