the paleomagnetic shipboard laboratory stores the physical properties of the samples in about 10 different tables, including and for the sample, and for the core, and and for the hole. the paleomagnetic shipboard laboratory also stores information about the core and hole, including holes with magnetic properties measured, holes with measurements on sections, and holes with the rest of the core. hole data table hole data table hole data table the paleomagnetic shipboard laboratory has a separate data table for each hole. the paleomagnetic shipboard laboratory stores the hole data in about 10 different tables, including and for the hole, and for the core, and and for the core, and and for the hole.
the srm features a mu-metal fluxgate magnetometer (fmg), a high-precision, computer-controlled superconducting 2g enterprises rock magnetometer (srm), and an automated core handling system (achs). the achs manipulates the apc core in precise and rapid fashion to optimize the recovery of rock samples from the upper and lower sediment layers. the srm is an active system that is capable of measuring diamagnetic and paramagnetic properties on samples at specific locations. the magnetometer is capable of performing on-line core analysis in the presence of high magnetic fields such as those encountered in the core housing and below the first few meters of the sedimentary column.
magnetic susceptibility is the ratio of the magnetic field produced by a given mass of the material to the field produced by a mass of pure magnetite. susceptibility is expressed as the relative magnetic permeability (the ratio of a magnetic flux to an electric current flux in a particular material). because of the high-pressure, constant temperature, and constant material environment present in the sedimentary column, the susceptibility measured at the core top is directly related to the susceptibility in the depositional environment and is measured with a similar tool (e.g., the magnetometer) in the laboratory.
