Explore the integration of magnetic and oxygen isotope stratigraphies in this 56-minute Bullard Lecture from the AGU Fall Meeting 2008. Delve into topics such as polarity time scales, magnetic stratigraphy, Arctic excursions, and magnetic properties with James E.T. Channell from the University of Florida's Department of Geological Sciences. Examine thermal demagnetization, IRM acquisition curves, and various analytical techniques including wavelet power, orbital power, and coherence. Gain insights into the correlation between magnetic and oxygen isotope data, and understand the implications for paleointensity studies and excursion durations.
