THE BASAL MELTING OF ANTARCTIC ICE SHELVES

该项目旨在确定南极冰架融化成海洋的机制。在变暖的海洋中，冰架基面融化的速度更快，导致南极洲的冰层消失，冰川速度加快，预计融化将对未来全球海平面上升做出更大贡献。通过独特的实验室实验、湍流解析计算和理论分析，该项目将评估融水、洋流、内波破碎以及大陆架和冰下洞穴之间的水交换所起的作用。这些结果将有助于我们理解南极洲的测量结果，并有助于更可靠地预测海平面上升。

The project aims to determine the mechanisms that govern melting of Antarctic ice shelves into the ocean. Faster basal melting of ice shelves in the warming ocean is contributing to loss of grounded ice from Antarctica and increased glacier speeds, and melting is projected to become a larger contribution to future global sea level rise. Using unique laboratory experiments, turbulence-resolving computation and theoretical analysis the project will evaluate the roles of meltwater, ocean currents, internal wave breaking and water exchanges between the continental shelf and sub-ice cavities. The results will assist our understanding of measurements made in Antarctica and more reliable predictions of sea level rise.
