The cohesion, or strength, of marine sediments of cores from ten sites in St. Andrew Bay was studied as a function of other sediment characteristics by multiple linear regression and non-linear regression. Strength, measured by unconfined compression of vane shear tests, is found to decrease as sediment water increases, to increase with depth in core, and to increase with increase in ratio of kaolinite to illite. All these variables are linearly related to strength, but they are also associated with second-order effects which may both increase and decrease strength. Penetration depends on sediment water content, mean grain size, sorting, and void ratio.
