Oceanic Variability from Southern Ocean Sediment Cores

As Antarctica changes, so does the ocean. The long-term evolution of the ice sheets and the shorter-term oscillations superimposed upon them, have produced far-reaching effects on the circulation and water masses of both hemispheres. In this section, we focus on the oceans' responses to G-I cycles over the last million years with emphasis on the last few cycles simply because they are generally the best documented. This younger part of the record is also assessed for the effects of millennial-scale change as driven from Antarctica but also from the NH. Here we review briefly the wealth of palaeoceanographic research and the reader is referred to the reference list as a window into an extensive literature.
