Paleoenvironments of the Bering Land Bridge at the End of the Last Glaciation

该奖项支持一项综合研究项目，以开发阿拉斯加西北部楚科奇海和白令海大陆架的年代地层和古环境记录。该项目将侧重于从现有岩心提取的晚更新世陆地和边缘海洋（沼泽）沉积物中的泥炭层古生物学。这些记录的发展将涉及对昆虫、花粉、植物大化石、介形虫和有孔虫的综合研究。该项目的目的是了解更新世古生态和白令陆桥的淹没历史。除了更好地了解更新世的古环境条件外，这项工作的结果还可以通过改进海平面变化记录来影响古气候学，并通过更好地年代学和了解白令陆桥来影响人类学。

This award supports an integrated research project to develop chronostratigraphic and paleoenvironmental records of the continental shelves of the Chukchi and Bering Seas, off northwestern Alaska. The project will focus on the paleontology of peat layers in late Pleistocene terrestrial and marginal marine (marsh) sediments from existing cores. Development of these records will involve an integrated study of insects, pollen, plant macrofossils, ostracods, and foraminifera. The goal of this project is to understand the Pleistocene paleoecology and the inundation history of the Bering land bridge. In addition to providing a better understanding of Pleistocene paleoenvironmental conditions, the results of this work have implications for paleoclimatology, through improved records of sea level change, and anthropology, through a better chronology and understanding of the Bering land bridge.
