Void ratio determinations on samples from the same approximate depths yielded values of , considerably closer to the void ratio values found for the sediment to depths of . m below the mudline. Bryant and others (1974) have attributed the "sensitive-like" nature of the e-log p curves (virgin curve which is concave up) to be characteristic of the Gulf of Mexico submarine sediments with void ratios greater than about A sample from a depth of m (core B-1) with an initial void ratio of less than was consolidated to a load of ^ kPa. The e-log p curve shows a broad recompression curve up to a preconsolidation pressure of X10^ kPa which is quite unlike the e-log p curves of the much higher void ratio (high porosity) overlying sedi- ment (fig. 37). Clearly this material represents a consider- ably greater degree of natural consolidation than the high void ratio sediment. Not
