Summary: We performed uniaxial consolidation tests on 41 whole-round samples from four sites along a shelf-slope transect (Integrated Ocean Drilling Program [IODP] Sites U1351-U1354) that were collected during Expedition 317. Each sample was loaded in 9-15 loading and unloading steps, with each step taking ∼24 h. The preconsolidation stress was estimated using a graphical procedure. However, this method has limitations because it requires that the transition from the re loading curve to the virgin compression curve is well defined on the semilogarithmic plot of void ratio versus vertical effective stress. The sediments are mostly strongly overconsolidated. In the uppermost 25 m, the maximum past effective overburden stress correlates very well among each site. Below this depth, the maximum past effective overburden stress tends to higher values at sites more distal to the slope (Sites U1353 and U1354) than at sites proximal to the slope (Sites U1351 and U1352).
