Collaborative Research : Reconstructing the Oceanic 13C Suess Effect Using a Novel Approach

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尝试开发一种方法来评估海洋中溶解无机碳的碳同位素组成(D 13C)的人为变化，即所谓的13C苏斯效应。这种方法的发展应允许使用新的WOCE/JGOFS/OACES d 13C-DIC和DIC数据集在全球范围内重建d13C-DIC和DIC Suess效应。这些重建将首次提供(1)人为13CO2与12个二氧化碳变化之间的关系的全球覆盖，(2)海洋DIC变化的总d13C，以及(3)DIC分布的工业化前的d13C。重建还应该对现代全球碳循环的模型者和古海洋学社区产生直接的好处。

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.
