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.
