This report contains the results of triaxial and consolidation-compression testing on selected cores taken by the Atlantic Margin Coring Project, a 60-day expedition to obtain core samples by drilling beneath the Continental Shelf and Slope of the eastern United States. The coring took place in July, August and September, 1976 aboard the D/V GLOMAR CONCEPTION, and penetrated as much as 310 meters below the sea floor at 19 sites (Figure 1) along the continental margin from Georgia to Georges Bank off New England in water depth ranging from 20 to 300 meters.
