Laboratory geotechnical deformation tests on a claystone test specimen from 619 m depth in Ocean Drilling Program Hole 1070A provide evidence of low effective yield stresses and capillary pressures (1.2Β±1.5 MPa) in the sediment section near the acoustic basement. Effects from negative pore-Β―uid pres
