A considerable portion of E. Antarctica ice (average of 1.6 km height) rests on bedrock of 2000+ ft above sea level. https://www.physicsforums.com/showthread.php?t=344123" Would such a core suffice to cover enough glacial and inter-glacial periods; giving an adequate sample? Would any evidence of oceanic sediment, current flows, foraminifora etc. be consistent with breaching of such isthmus; hence consistent with significant sea level elevation, consistent with E. Antarctica dissolution? Would there be any other possible causes of significant sea level elevation? Might we thus have a historical record of whether or not E. Antarctica is stable; using the Isthmus of Panama as our proxy?
