This award supports research that focuses on the collection and analysis of palynomorphs and megafossils of Permian and Triassic age from the Beardmore Glacier region in Antarctica. Research will include the biostratigraphy, correlation, and biology of plants preserved as impressions, compressions and permineralizations. Systematic collections will be made of samples with the aim at recovering palynomorphs that will help to better correlate the Buckley, Fremouw and Falla Formations (Beacon Supergroup) with those in other areas of Antarctica and other Gondwana continents. A component of this research will investigate digenetic effects on palynomorphs from areas (e.g., Mt. Achernar) where pollen is preserved in the vicinity of diabase sills. In addition, palynomorphs and megafossils (where available) will be collected in the vicinity of known vertebrate localities in order to better correlate these deposits and to contribute to paleoenvironment reconstructions. Impression/compression specimens will also be collected with the aim to better understand the floral composition and its possible use in biostratigraphy and biogeography.

该奖项支持的研究重点是收集和分析南极比尔德莫尔冰川地区二叠纪和三叠纪的孢粉化石和巨型化石。研究将包括生物地层学、对比和作为印迹、挤压和矿化保存的植物的生物学。将对样品进行系统收集，目的是恢复孢粉形态，这将有助于更好地将巴克利、弗雷穆夫和法拉地层(Beacon Supergroup)与南极洲其他地区和其他冈瓦那大陆的地层相关联。这项研究的一个组成部分将调查来自地区(例如，山)的双基因对孢子体的影响。Achernar)在辉绿岩岩床附近保存花粉。此外，将在已知脊椎动物所在地附近收集孢粉和巨型化石(如有)，以便更好地对这些沉积物进行对比，并为古环境重建做出贡献。还将收集印模/压缩标本，目的是更好地了解植物的组成及其在生物地层学和生物地理学中的可能用途。
