Unravelling the elements in ocean sediments

Liao and Tom recently visited the Integrated Ocean Drilling Program (IODP) center in College Station, Texas to analyse sediment cores obtained during IODP expedition 371 to the Tasman Sea. They performed X-ray fluorescence experiments on the cores, a technique that allows to determine chemical compositions of the sediments at very high speeds. This will allow to correlate variations in the magnetic signals, for example, NRM intensities, with variations in iron content along the section.
