This award is for support of a study of late Neogene foraminifera and molluscs from Dry Valleys glaciomarine sediment. Oxygen, carbon, and strontium isotopes will be measured on foraminifera from the thick glaciomarine sequences in Eastern Taylor Valley, and molluscs from the Prospect Mesa gravels in central Wright Valley. The principal result will be a well-dated history of the temperature and salinity for late Neogene fjords in Taylor and Wright Valleys. Because fjord inflow comes from the Ross Sea, this history reflects that of the principal water mass in the Ross Sea which is stamped with the climate of the Ross Sea region. This is a collaborative proposal between Prentice at the University of Maine, Ishman of the U.S. Geological Survey, and Berkman at The Ohio State University.

该奖项旨在支持对干谷冰川沉积物中新近纪晚期有孔虫和软体动物的研究。 将对泰勒谷东部厚冰洋序列的有孔虫和莱特谷中部 Prospect Mesa 砾石的软体动物进行氧、碳和锶同位素测量。 主要成果将是泰勒谷和赖特谷新近纪晚期峡湾温度和盐度的详细历史记录。 由于峡湾的流入来自罗斯海，这段历史反映了罗斯海主要水体的历史，并带有罗斯海地区气候的印记。 这是缅因大学的普伦蒂斯、美国地质调查局的伊什曼和俄亥俄州立大学的伯克曼之间的合作提案。
