Welcome
Shipboard paleomagnetists conduct paleomagnetic and rock magnetic measurements of recovered rocks and sediment to construct a magnetostratigraphy for each site and to examine its paleomagnetic and tectonic history. Typically, 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 with using the superconducting cryogenic rock magnetometer (SRM), although measurements are ceased if data quality are poor. Discrete samples (8 cc paleomagnetic cubes) are . In addition, discrete samples (~6-10 cm3Â paleomagnetic cubes or mini-cores) may be taken from the working half of cores for additional measurements . We will discuss a shipboard sampling scheme prior to arriving at our first siteusing the SRM or spinner magnetometers as well as other instruments in the lab.
