Paleomagnetism

Layout of the Paleomagnetism Lab on the Core Deck. Top of the image is towards the front of the ship.

 


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.
