了解南极冰盖将如何应对全球变暖依赖于它在过去的表现。使用数值模型是定量预测未来的唯一手段,但由于现在和过去地形数据的局限性,以及在了解次表层海洋、冰川和水文过程如何相互作用方面的局限性,这一工作受到了阻碍。阐明这些过程的多样性和相互作用,在多个时空尺度上运作,对于模拟南极系统的演变至关重要,需要在具有挑战性的地点进行直接观测。由于这些过程不遵守学科界限,我们未来的研究也不应该。在南极系统中研究不足的是冰盖、海洋和地质基底之间的地下界面。在这里,作者回顾了我们对这些组成部分的理解,并提出了整体动态建模的新途径,以实现对过去,现在和未来极地气候的统一理解。
Understanding how the Antarctic ice sheet will respond to global warming relies on knowledge of how it has behaved in the past. The use of numerical models, the only means to quantitatively predict the future, is hindered by limitations to topographic data both now and in the past, and in knowledge of how subsurface oceanic, glaciological and hydrological processes interact. Incorporating the variety and interplay of such processes, operating at multiple spatio-temporal scales, is critical to modeling the Antarctic’s system evolution and requires direct observations in challenging locations. As these processes do not observe disciplinary boundaries neither should our future research. Understudied in the Antarctic system are the subsurface interfaces between ice-sheet, ocean and geological substrate. Here, the authors review our understanding of these components and propose new avenues of holistic dynamic modeling to achieve a unified understanding of past, present and future polar climate.
