研究方向及成果

同位素及元素地球化学，古气候/古海洋/古环境，第四纪气候变化，全球碳 循环，海洋碳酸岩体系，大气 CO2变化，海洋酸化，生物碳酸岩成因机理，古环境指标开发及测试，古洋流与气候变化耦合关系。主要成果如下：

（1）建立可靠有效的生物碳酸岩元素 ICPMS 测试方法 (Yu et al., G3, 2005)，对小达 60ug 的样品同时 测十几个微量元素含量，此方法为国际首次精确可靠的分析有孔虫 B/Ca 比值。

（2）有效的区分出可靠的生物碳酸岩清洗方法（Yu et al., G3, 2007)，两位评审人评价该研究与以往 研究截然不同，提供了独到的见解，为有孔虫的洗涤研究提供了最前沿的信息。

（3）系统研究海洋生物碳酸岩微量元素控制因素，这些元素包括 B（Yu et al., Paleoceanography, 2007; Yu & Elderfield, EPSL, 2007）, Mg （Yu & Elderfield, EPSL, 2008), U (Yu et al., GCA, 2008), 和 Sr(Yu et al., QSR, 2014)元素，这些研究为全球元素和碳的循环循环规律提供了可靠的基础。
