Version 2 - Friction velocity dependence of sediments from the Nankai Trough, Japan

To investigate frictional behavior of sediments along the Kumano transect in the Nankai Trough, Japan, friction experiments were conducted using a single-direct shear device at MARUM, University of Bremen under room temperature conditions with 3.5% simulated seawater. Intact sediment cores from the input, prism toe, and inner prism sites collected by the IODP NanTroSEIZE project were tested. In this dataset, parameters of the rate- and state-dependent friction law for each sample were reported, which were obtained by the velocity step tests from 0.01 to 30 μm/sec.
