Career: Geochemical Approaches to Oceanography and Climatology: A Plan for Research and Education

小行星9733688 该奖项支持一项研究，教学和课程开发计划，重点关注有关海洋和气候在一系列时间尺度的历史问题。 在一个项目中，我们将研究热带太平洋过去几十年的海洋环流。 使用珊瑚作为海洋表面放射性碳含量的固定监测器，我们将研究炸弹产生的放射性碳如何渗透到海洋表面，然后通过上升流和表面洋流的运动重新分布，基本上增加了一个时间维度的信息从地表水采样GEOSECS程序。 第二个项目 是 关注于重建 在几千年前的时间窗口内，印度尼西亚低压系统位置的年际变化，目的是更好地了解ENSO如何对平均气候状态的变化作出反应。 我们将从印度尼西亚隆起的珊瑚礁中收集珊瑚化石，这些珊瑚化石来自现代珊瑚的氧同位素记录显示与ENSO有很强的相关性的地方。 全新世的时间序列 将与海洋环流模型的预测进行比较。 对于教学部分，该奖项将支持一项新的倡议，该倡议为政府和公共政策学生提供气候学研究的机会，作为施拉格研究小组的参与者。

9733688 Schrag This award supports a program of research, teaching and curriculum development focused on questions regarding the history of oceans and climate over a range of timescales. In one project, we will examine the last several decades of ocean circulation in the tropical Pacific. Using corals as stationary monitors of surface ocean radiocarbon content, we will examine how bomb-produced radiocarbon has penetrated into the surface ocean, and then has been redistributed by upwelling and the movement of surface currents, essentially adding a time dimension to the information gained from surface water sampling by the GEOSECS program. The second project is concerned with reconstructing interannual variability in the position of the Indonesian Low Pressure System for windows of time several thousand years ago, with the objective of better understanding how ENSO responds to changes in the mean climate state. We will collect fossil corals from uplifted coral reefs in Indonesia from locations where oxygen isotope records from modern corals show strong correlation with ENSO. The Holocene timeseries we produce will be compared with predictions from ocean circulation models. For the teaching component, the award will support a new initiative which provides students in government and public policy exposure to research in climatology as a participant in Schrag's research group.
