This project will extend a long-term program to measure trends of atmospheric carbon dioxide (CO2) and dissolved inorganic carbon (DIC) in seawater, and their 13C/12C isotopic ratios. These measurements, that date back several decades, will be used along with other climatic data, such as satellite-borne radiometric data of greenness of land vegetation, to estimate net exchanges of CO2 between the oceans, the atmosphere, and the terrestrial biosphere. This research is relevant to understanding the impacts of climate and human activities on the global carbon cycle. Data collected as part of this project will become part of the Carbon Dioxide Information Analysis Center (CDIAC) data archive.

该项目将扩展一项长期计划，以测量大气中二氧化碳（CO2）和海水中溶解无机碳（DIC）的趋势及其13 C/12 C同位素比值。 这些可追溯到几十年前的测量数据将沿着其他气候数据，如关于陆地植被绿度的卫星辐射测量数据，用于估计海洋、大气和陆地生物圈之间的二氧化碳净交换。 这项研究有助于了解气候和人类活动对全球碳循环的影响。 作为该项目的一部分收集的数据将成为二氧化碳信息分析中心（CDIAC）数据档案的一部分。
