项目摘要
Costs of rapid sea level rise globally to infrastructure (houses, roads, and farms, etc.) is likely to be large. A possible source of water for sea level rise is the West Antarctic Ice Sheet, and Thwaites Glacier in particular. Ice sheets and glaciers contain vast quantities of water (in the form of ice) that is continually shed to the ocean, and continually replenished by snowfall (from water that evaporates from the oceans). If the amount of ice that Thwaites Glacier loses to the ocean over the next decades is much greater than the amount it receives as snowfall, then sea level in all the world's oceans would rise, possibly as much as a meter (approximately 3 feet). In order to estimate how likely such a catastrophic scenario would be, we need to better understand the surface over which Thwaites Glacier slides. If we can better characterize that layer ("is to smooth? Is it rough? Is it soft? Is it hard?"), then computer models of Thwaites would be much improved and we can make better projections of the amount of ice that Thwaites Glacier would shed to the ocean.
全球海平面快速上升对基础设施(房屋、道路和农场等)造成的成本可能会很大。海平面上升的一个可能的水源是南极西部冰盖,特别是思韦茨冰川。冰盖和冰川含有大量的水(以冰的形式),这些水不断地流入海洋,并不断地被降雪(从海洋蒸发的水)补充。如果斯韦茨冰川在未来几十年内流失到海洋中的冰量远远大于降雪量,那么世界上所有海洋的海平面都将上升,可能高达1米(约3英尺)。为了估计这种灾难性情景的可能性,我们需要更好地了解Thwaites冰川滑动的表面。如果我们能更好地描述该层(“是平滑?很粗糙吗?是软的吗?很难吗?),那么斯韦茨的计算机模型将得到很大的改进,我们可以更好地预测斯韦茨冰川将流入海洋的冰量。
