Density mecsurements were obtained by inserting a chrome cylinder of known 

 weight and volume into the core and extruding the core from the liner for a distance 

 equal to the length of the cylinder. After trimming and wiping the exterior and ends 

 of the cylinder clean of excess sediment, the weight of the sediment and its container 

 were obtained. This procedure measured the wet unit weight of the sedimentary 

 material . 



Water content of the sediment was measured by longitudinally splitting the 

 increment used in the density measurement, extracting a sufficient quantity of the 

 sediment from the center of the increment, weighing the sample immediately, drying 

 at 105°C, and reweighing. The water content was calculated by the equation: 



\A/ . r- . . fo/\ (Wet Weight - Dr y Weight) 



Water Content, w(%), = ^ J^ ,., . / ^ x 100.

The void ratio was determined by the equation:

 Void Ratio, e, = —

where V - — ^ *-

and Wy= 1 -Vj. 



Porosity of the sediment was obtained by the equation: 



Porosity (%) = T , I \/ I X 100 = j^ . 



' ^ ' Total Volume I + e 



The values presented In Table II show approximately 70 percent of the cores in 

 the near-flank area decreasing in water content, void ratio, and porosity with depth 

 in the sediment and increasing in density with depth. However, particle grain size 

 is strikingly similar through the sediment, and the mineralogical composition is almost 

 wholly CaCOo. The increase in density with depth in the sediment is most likely the 

 result of compaction and consequent loss of interstitial water. 



Below are the maximum, minimum, and average values of the properties tabulated 

 in Table II:
