The cruise will address goals set by the Antarctic CRC Natural Variability (sediments) sub-program, which are to promote a better understanding of global climate change by providing statements of the Antarctic and Southern Ocean palaeoenvironments over the following time intervals: (A)0-10,000 years (post-glacial warming) (B)0-160,000 years (last glacial cycle) (C) 0-5,000,000 years (Pliocene "warming" of Antarctica) These goals will be achieved by studying the Antarctic and Southern Ocean sedimentary record for evidence of Antarctic ice sheet and Southern Ocean circulation changes.
