Overview: This dataset includes core physical properties (e.g., bulk density, porosity, P-wave velocity) and magnetic susceptibility data for MV0811-14JC measured on the multisensor track (MST, Geotek Multisensor Core Logger).

Methods: MV0811-14JC contains 10 sections. MST and magnetic susceptibility data were first obtained using the Geotek core logger on board Melville at 1-cm interval in November, 2008. In 2010, MST and magnetic susceptibility of the first 3 sections were measured again at 0.5-cm interval using the Geotek core logger at the LacCore Facility, University of Minnesota.
