Figure 3. Example of millennial- and suborbital-scale variability on top of longer orbital periods of 40 k.y. in the magnetic susceptibility of sediments from Site 983. The susceptibility signal reflects changes in mineral input to the site which varies with the state of climate. This interval is from about 1.9 Ma. Depth is based on a composite scale obtained from correlating results from the Site 983 holes.
