Latest Neogene Northeast Asian Climate Variability, Focusing on the Middle Pliocene Warming Event

该奖项支持一项关于明显广泛和持久的上新世变暖的时间和空间性质的研究，该变暖已被引用为全球气候变暖的模型。将每隔10-20ka对日本海和西北太平洋的海洋孢粉和硅质微型动物进行分析，以：(1)记录东北亚陆地生态系统的性质和变化速度：(2)确定近海水团的性质和变化以及与之相关的西北太平洋和日本海的海洋和环流变化；(3)建立了上新世早期和中期东北亚季风变化的时间和频率模型：(4)将我们的资料与其他地区的可比古气候资料进行比较，以评估上新世暖事件的时空特征；(5)提供区域陆地和海洋古气候资料，以验证全球气候变暖中轨道、大气和海洋强迫作用的大气环流模式实验结果。

This award supports a study of the temporal and spatial nature of an apparently extensive and protracted Pliocene warming which has been cited as a model for global climate warming. Marine pollen and siliceous microfauna from the Japan Sea and the northwest Pacific will be analyzed at 10-20ka intervals in order to : (1) document the nature and rate of variation of northeast Asian terrestrial ecosystems; (2) define the nature and variation in offshore water masses and associated northwest Pacific and Sea of Japan oceanographic and circulation changes; (3) develop a model of early and middle Pliocene northeast Asian monsoon variability in the time and frequency domain; (4) compare our data with comparable paleoclimatic data elsewhere to assess the spatial and temporal character of the Pliocene warm event; (5) contribute regional terrestrial and marine paleoclimatic data to verify the results of general circulation model experiments investigating the roles of orbital, atmospheric and oceanic forcing in global climate warming.
