Description:
We present new paleomagnetic data for Quaternary u channel samples from two deep-sea gravity cores
from the west Pacific Southern Ocean. These cores were recovered in the Antarctic summers 1995–1996
during the oceanographic cruise of the R/V Italica. One was recovered beneath the present-day Antarctic
Polar Front (Anta 95-157), and the other is from within the Antarctic Zone (Anta 96-16). The Matuyama-
Brunhes boundary has been identified in both cores, with a longer history of sedimentation available in
Anta 96-16. A detailed rock magnetic study shows discrete occurrences of ice rafted debris, which were
influenced by 100-kyr orbital eccentricity variations during the Brunhes Chron. This is consistent with the
main periodicity of the climate system since the mid-Pleistocene climate transition.
