Overview

Shipboard paleomagnetists conduct paleomagnetic and rock magnetic measurements of recovered rocks and sediment for a variety of studies, such as those on magnetostratigraphy, geomagnetism, tectonics, and environmental change. Typically measurements are conducted on the archive half of each core using the 2G Enterprises 760-4K Superconducting Rock Magnetometer (SRM). In addition, discrete samples (~6-10 cm3 paleomagnetic cubes or mini-cores) may be taken from the working half of cores for additional measurements using the SRM or spinner magnetometers as well as other instruments in the lab.
