The Chronology of Late Neogene Antarctic Climate Change: Dry Valleys Fjord Fossil Evidence: Collaborative Research

该奖项是为了支持对干谷冰川海洋沉积物中新世晚期有孔虫和软体动物的研究。氧、碳和锶同位素将在东泰勒谷厚厚的冰川期海洋序列中的有孔虫和赖特谷中部Prospect Mesa砾石中的软体动物上进行测量。主要的结果将是泰勒和赖特山谷中新纪晚期峡湾的温度和盐度的准确历史。由于峡湾的流入来自罗斯海，这一历史反映了罗斯海主要水团的历史，这一历史烙印着罗斯海地区的气候。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共同提出的一项建议。

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.
