Relationship of wet unit weight to water content for the Gulf of Mexico (after Bryant and Trabant, 1972) Wet Unit Weight and Porosity The well defined correlation between wet unit weight, porosity, and water content for a given specific gravity was discussed ear- lier. Although not shown, the same inverse relationship of wet unit weight to porosity exists for wet unit weight and void ratio. It is commonly accepted that wet unit weight increases as depth be- low the sea floor increases. This is obviously not a linear func- tion but one dependent on such factors and changes in grain size, cementation, overburden, depositional history, etc. Bryant and TrabanC (1972) have developed a least squares curve, based on their 1480 analyses from the Gulf of Mexico, showing the increase in wet unit weight with depth (Fig. 7). It is clear from this figure that such a curve can serve only as a very rough rule of thumb and con- firms the generalization that density increases as depth of burial increases. Both wet unit weight and porosity are closely correlated with s-ediment grain size. Although the relationships are not linear throughout their respective limits, there is a definite inverse correlation between mean grain size and porosity (Hamilton, 1972) and a directly proportional relationship with wet unit weight. 971.
