Summary: We performed uniaxial, constant-rate-of-strain consolidation experiments and grain size analyses to characterize the transport and deformation properties of eight samples from Integrated Ocean Drilling Program Expedition 341 Sites U1420 and U1421. Permeability, compression indexes, and swelling indexes were determined from consolidation experiments. Permeability values range from 1.2×10-17 m2 to 2.0×10-13 m2, are positively correlated with median grain diameter, and exhibit little depth dependence. Compression indexes, which define stress-strain behavior during virgin consolidation, range from 0.13 to 0.25 and are negatively correlated with median grain diameter. Swelling indexes, which define stress-strain behavior during elastic reconsolidation, range from 0.023 to 0.036 and are best correlated with compression indexes, generally being equal to 16.8% of the compression index value. Median grain diameters determined by Stokes settling analysis range from 0.00232 to 0.0969 mm, with samples consisting of roughly equal portions of sand, silt, and clay. The standard deviations of the grain size distributions indicate that the sediment grains are very poorly sorted.
