ABOUT DANIEL'S WORK
Daniel Schrag investigates the history and mechanisms of global climate change by combining empirical geochemical measurements with models of chemical and oceanographic processes.
Schrag’s investigation of changes in oceanic carbon chemistry revealed that the biosphere essentially shut down several times in the distant past, when the globe was apparently completely covered with glacial ice. He has also determined that the oceans cooled nearly to the freezing point in the most recent ice age, resolving a longstanding debate. To study the El Niño climatic oscillations over the last decades and in the geologic past, Schrag uses the isotopic composition of coral shells to assess the state of the ocean at the time they were alive. His research underscores the dependence of effective environmental policy on a comprehensive understanding of the physical, chemical, and biological processes that shape the biosphere.
BIOGRAPHY
Schrag is a professor of geochemistry in the Department of Earth and Planetary Sciences at Harvard and director of its Center for the Environment. He taught at Princeton University from 1993-1997. His articles have appeared in such journals as Science, Paleoceanography, and Nature.
Schrag received a B.S. (1988) from Yale University and a Ph.D. (1993) from the University of California, Berkeley.

关于丹尼尔的工作
丹尼尔-施拉格通过将经验地球化学测量与化学和海洋学过程的模型相结合,研究全球气候变化的历史和机制。
施拉格对海洋碳化学变化的调查显示,在遥远的过去,生物圈基本上关闭了好几次,当时全球显然完全被冰川冰覆盖。 他还确定,在最近的冰河时期,海洋几乎冷却到冰点,解决了一个长期的争论。 为了研究过去几十年和地质学上的厄尔尼诺气候震荡,施拉格利用珊瑚壳的同位素组成来评估它们活着时的海洋状态。 他的研究强调了有效的环境政策取决于对塑造生物圈的物理、化学和生物过程的全面理解。
个人简历
施拉格是哈佛大学地球和行星科学系的地球化学教授和环境中心主任。 1993-1997年,他在普林斯顿大学任教。 他的文章出现在《科学》、《古海洋学》和《自然》等杂志上。
施拉格在耶鲁大学获得学士学位(1988年),在加州大学伯克利分校获得博士学位(1993年)。
