来自模型和地质数据的越来越多的证据表明，南极冰盖的行为可能不稳定，并随着气候变暖而迅速消退，这是推动努力改进对南极冰量对未来海平面上升贡献的估计的一个关键因素。在这里，我们回顾了南极自始新世中期气候最佳(约.50 Ma)，为未来从南极大陆内陆的冰下湖泊和沉积盆地中恢复沉积岩芯提供一个框架。虽然现有的岩心清单对南极洲的生物和气候演化产生了重要的见解，但地层有大量且往往很长的时间间隔，提供了一个随时间变化的“快照”框架。需要更多的岩芯和现有岩芯的更多工作，以使南极记录与记录全球冰量和深海温度演变的更连续的“远场”记录保持一致。为了实现这一目标，我们主张建立一个综合的钻探和取心任务组合，其中包括使用基于船舶和海冰/冰架的钻井平台的现有方法以及最近开发的基于海底的钻探和冰下通道系统。最后，我们回顾了需要克服的关键技术问题。
Mounting evidence from models and geological data implies that the Antarctic Ice Sheet may behave in an unstable manner and retreat rapidly in response to a warming climate, which is a key factor motivating efforts to improve estimates of Antarctic ice volume contributions to future sea-level rise. Here, we review Antarctic cooling history since peak temperatures of the Middle Eocene Climatic Optimum (approx. 50 Ma) to provide a framework for future initiatives to recover sediment cores from subglacial lakes and sedimentary basins in Antarctica's continental interior. While the existing inventory of cores has yielded important insights into the biotic and climatic evolution of Antarctica, strata have numerous and often lengthy time breaks, providing a framework of ‘snapshots’ through time. Further cores, and more work on existing cores, are needed to reconcile Antarctic records with the more continuous ‘far-field’ records documenting the evolution of global ice volume and deep-sea temperature. To achieve this, we argue for an integrated portfolio of drilling and coring missions that encompasses existing methodologies using ship- and sea-ice-/ice-shelf-based drilling platforms as well as recently developed seafloor-based drilling and subglacial access systems. We conclude by reviewing key technological issues that will need to be overcome.
