The Antarctic cryosphere is an important driver of global climate change and ocean circulation. The Antarctic Ice Sheet is comprised of the stable, terrestrially-based East Antarctic Ice Sheet (EAIS) and the marine-based West Antarctic Ice Sheet (WAIS) that may be prone to a collapse that would contribute over 3 m to global sea level rise. The Antarctic Ice Sheets have unique evolutionary histories and understanding how they have influenced and been influenced by global changes through the Cenozoic will yield a more robust understanding of their response to future climate change. 98% of Antarctica is currently covered in ice, posing challenges for investigators. Much of our understanding of the evolution of the Antarctic cryosphere has been developed from far field oxygen isotope records of global temperature and ice volume change; however, more direct records of Antarctic Ice Sheet dynamics from the continent and margin conflict with interpretations derived from these records. The Ross Sea embayment in ...
