AntArchitecture: constraining East Antarctic Ice Sheet dynamics with radar-derived englacial stratigraphy and structure

该项目将重点追踪关键层位，以利用ICEGRAV和极地缺口调查获得地层信息(图1)。利用海床和冰层特征，结合填图的冰川地层，可以研究地层的形成和变形过程。通过使用在南极和EPICA采集的与雷达数据相交的冰深度模型和/或冰芯(Cavitte等人，2016；温特等人，2019a)，该项目可以重建韦德尔海区域内的冰盖历史。这将限制ISM参数，包括增强的地热和底部剪切的影响，以及对滑动、内部变形和由此产生的冰盖稳定性的影响。

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.
