Bulk density, porosity, and matrix density were measured on 88 basalt core plugs from Ocean Drilling Program Site 1256. Shipboard measurements using the multisensor track were reprocessed and edited to minimize the effects of core segmentation and calibration problems and are presented in this data report.
