The Abundance of the Stable Carbon Isotopic Ratio of Atmospheric Carbon Dioxide and Oceanic Carbon in Relation to the Global Carbon Cycle and Climatic Change

小行星9711882 该项目将继续基林教授的40年大气二氧化碳时间序列和他的测量溶解无机碳（DIC）和滴定碱度（TA）的表面海水在一系列站（13年的记录）。 这项工作的长期目标是记录碳循环如何对人类活动和气候变化做出反应。 作为这一科学目标的一部分，该项目将继续生成关于同一空气和水样本中二氧化碳和DIC的稳定碳同位素比率的时间序列数据，以确定对海洋和陆地碳循环的影响。 稳定同位素信息将与实验室研究相结合，根据DIC和TA数据高精度地预测海水中CO2的分压。 最后，将把时间序列数据集中的模式与全球温度和植被绿度记录中观察到的模式进行比较。 这一额外任务旨在通过探测大气CO2的时间和空间模式，了解自然系统中碳的通量和储存及其与气候的关系。 ATM-9711882

9711882 Keeling The project will continue Professor Keeling's 40-year atmospheric carbon dioxide time series and his measurements of dissolved inorganic carbon (DIC) and titration alkalinity (TA) of surface sea water at an array of stations (a 13-yr record). The long term goal of this work is to document how the carbon cycle is responding to human activities and to variability in climate. As part of this science objective, the project will continue to produce time series data on the stable carbon isotopic ratio of carbon dioxide and DIC on the same samples of air and water, to identify impacts on the oceanic and terrestrial carbon cycles. The stable isotope information will be combined with laboratory studies to predict to high accuracy the partial pressure of CO2 in sea water from DIC and TA data. Finally, the patterns in the time series data sets will be compared to patterns observed in records of global temperature and of the greenness of vegetation. This additional task is intended to produce knowledge about the fluxes and storage of carbon in natural systems and their relation to climate by detecting temporal and spatial patterns in atmospheric CO2.
