This award supports the study of Permian-Triassic fluvial deposits in the Beardmore Glacier region, Antarctica, which promises significant new insights into fluvial sedimentology, the evolution of the Transantarctic foreland basin, and the relationship of the Transantarctic basin with other Gondwana basins. Major objectives are: (1) to appraise fluvial channel and flood-plain depositional models; (2) to determine internal (e.g. channel processes) and external (e.g. climate, tectonic activity, and basin subsidence) controls on sedimentation; (3) to achieve a better understanding of the Late Paleozoic-Early Mesozoic Transantarctic basin including subsidence history, climate, and tectonic activity along the adjacent paleo-Pacific margin of Antarctica; and (4) to reconstruct environmental settings for Permo-Triassic floras and Triassic vertebrate faunas in conjunction with field parties engaged in paleontologic studies.

该奖项支持对南极洲比尔德莫尔冰川地区二叠纪-三叠纪河流沉积的研究，这将为河流沉积学、横贯北极前陆盆地的演化以及横贯北极盆地与其他冈瓦那盆地的关系提供重要的新见解。主要目标是：(1)评价河流和洪泛平原沉积模式；(2)确定沉积的内部(如河道过程)和外部(如气候、构造活动和盆地沉降)控制；(3)更好地了解晚古生代-早中生代横贯南极的盆地，包括邻近的南极古太平洋边缘的沉降史、气候和构造活动；(4)与从事古生物研究的野外考察队合作，重建二叠纪-三叠纪植物群和三叠纪脊椎动物群的环境。
