The empirical equation to express the relationship of sea 
water pressure and depth as listed in Table 5 is represented 
by the parabolic equation: 
i aA - 6 f? 2 
P 14008242.333x10 "2 Eq. 1^ 
where 
P sea water pressure in decibars 
Z sea water depth in meters. 
The error of Eq. 14 is presented in Table 6.

Similarly, the empirical equation to express the relationship 
of sea water density and depth is represented by the parabolic 
equation: 
6 1152 
p 1.0281344,812x10 ^2-5.167x10 ^ Z Ed. 15 
p Sea water density in grams per milliliter (old) 
Z sea water depth in meters. 
Density vs. depth data determined from Ref. 6 is the base 
data from which the constants were chosen to derive Eq. 15. 
The error of Eq. 15 is presented in Table 7.
