ABSTRACTOCE-0136814 / OCE-0136907In this project researchers at the Woods Hole Oceanographic Institution and the University of Washington will attempt to develop a method to evaluate anthropogenic changes in the carbon isotopic composition (d 13C) of dissolved inorganic carbon (DIC)in the oceans, the so-called 13C Suess effect. Development of this method should permit reconstruction of the d 13C-DIC and DIC Suess effect globally using both the new WOCE/JGOFS/OACES d 13C-DIC and DIC datasets. These reconstructions will provide, for the first time, global coverage of (1) the relationship between the anthropogenic 13CO2 and 12 CO2 changes, ( 2) the total d 13C of DIC change in the oceans, and (3) the pre-industrial d 13C of DIC distribution. The reconstructions should also be of immediate benefit to modelers of the modern-day global carbon cycle and to the paleoceanographic community.

在这个项目中，伍兹霍尔海洋研究所和华盛顿大学的研究人员将试图开发一种方法来评估海洋中溶解无机碳（DIC）的碳同位素组成（d 13 C）的人为变化，即所谓的13 C苏斯效应。 该方法的开发应允许使用新的WOCE/JGOFS/OACES d 13 C-DIC和DIC数据集全局重建d 13 C-DIC和DIC Suess效应。 这些重建将首次提供（1）人为13 CO2和12 CO2变化之间的关系，（2）海洋DIC变化的总d 13 C，以及（3）工业化前DIC分布的d 13 C的全球覆盖范围。 这些重建也应该对现代全球碳循环的建模者和古海洋学界有直接的好处。
