Antarctic climate warming and atmospheric CO2 rise during the last deglaciation may be attributed in part to sea ice reduction in the Southern Ocean. Yet, glacial–interglacial Antarctic sea ice dynamics and underlying mechanisms are poorly constrained, as robust sea ice proxy evidence is sparse.
Although many Quaternary records have allowed the study of major glacial-interglacial change in the … Southern Ocean, Holocene records from deep-sea cores are few and far between and are currently … limited to the South Atlantic. Low sedimentation rates combined with deep seafloors…
The Southern Hemisphere westerlies in the southwest Pacific are known to have waxed and waned numerous times during the last … two glacial cycles, though even semi-continuous histories of the westerlies extend back no more than about 20,000 years.
