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.

该奖项支持一个综合研究项目，以开发阿拉斯加西北部楚科奇和白令海大陆架的年代地层学和古环境记录。该项目将重点研究晚更新世泥炭层的古生物学，以及现有岩心的陆地和边缘海洋(沼泽)沉积物。这些记录的发展将涉及对昆虫、花粉、植物大型化石、介形类和有孔虫的综合研究。该项目的目的是了解更新世的古生态和白令大陆桥的淹没历史。除了更好地了解更新世的古环境条件外，这项工作的结果还对古气候学和人类学有影响，因为这项工作改进了海平面变化的记录，通过更好的年代学和对白令大陆桥的了解。
