This award will support a long-term research stay in Japan for Thomas M. Cronin, U.S. Geological Survey, to conduct collaborative research with Noriyuki Ikeya at the Institute of Geosciences, Shizuoka University, Japan. The objective of this project is to develop a quantitative method for the paleoclimatic study of Neogene and Quaternary marine deposits of Japan and the western North Pacific Ocean. Building upon a previous Cronin-Ikeya paleoclimatic study which applied a qualitative analysis of Ostracoda, a small, bivalved Crustacea which is easily fossilized, this project will utilize the extensive ostracode collection and water temperature data which are available at Shizuoka University. After a quantitative analysis of the ostracode samples at different water temperatures, the team will employ Dr. Cronin's methodology to develop a transfer function for the osctracodes and to derive equations for computing summer and winter paleotemperatures from Pliocene and Quaternary fossil ostracode assemblages from the western North Pacific. The research results will be applied to measure the climatic change during the middle Pliocene period.

该奖项将支持美国地质调查局的Thomas M.Cronin长期在日本进行研究，与日本静冈大学地球科学研究所的Noriyuki Ikeya进行合作研究。该项目的目的是开发一种定量方法，用于日本和西北太平洋新近系和第四纪海相沉积的古气候研究。在之前的Cronin-Ikeya古气候研究的基础上，该研究对介形类进行了定性分析，介形类是一种很容易石化的小型双壳甲壳类动物，该项目将利用静冈大学提供的广泛的介形虫收集和水温数据。在对不同水温下的介形虫样本进行定量分析后，该团队将使用克罗宁博士的方法来开发介形虫的传递函数，并根据西北太平洋上新世和第四纪的介形虫化石组合推导出计算夏季和冬季古温度的方程。研究成果将应用于上新世中期气候变化的测量。
