Figure F2. The effect of a nonmagnetic core barrel on the sediment NRM of Hole 1235C. Sediments recovered with a nonmagnetic core barrel (odd-numbered cores; shaded) had initial NRM intensities significantly lower than sediments recovered with a normal steel (magnetic) core barrel (even-numbered cores). Both the nonmagnetic and steel core barrels had steep positive inclinations prior to demagnetization. After AF demagnetization, the inclinations of the nonmagnetic core barrels are close to the expected inclinations due to the Earth's magnetic field at this site. Even after AF demagnetization, the inclinations of the steel core barrels deviate from the expected values.
