The project will focus on tracing key horizons to obtain stratigraphic information using ICEGRAV and Polar GAP surveys (Fig.1). Using bed and ice characteristics, combined with the mapped englacial stratigraphy, processes which have formed and deformed the stratigraphy can be investigated. By using ice-depth models and/or ice cores taken at the South Pole and EPICA, which intersect radar data (Cavitte et al, 2016; Winter et al, 2019a), this project can reconstruct ice sheet history within the Weddell Sea Sector. This will constrain ISM parameters, including the influence of enhanced geothermal heat and basal shear and the impacts on sliding, internal deformation and consequential ice sheet stability.

该项目将侧重于追踪关键层位，以利用ICEGRAV和Polar GAP调查获得地层信息（图1）。利用河床和冰的特征，结合绘制的冰内地层图，可以研究地层的形成和变形过程。通过使用南极和EPICA的冰深模型和/或冰芯，这些模型和冰芯与雷达数据相交（Cavitte等人，2016年; Winter等人，2019年a），该项目可以重建威德尔海域内的冰盖历史。这将限制ISM参数，包括增强的地热和基底剪切的影响以及对滑动、内部变形和随之而来的冰盖稳定性的影响。
