Scientists from Woods Hole Oceanographic Institution and the Woods Hole Research Center will characterize the sources, pathways, and timescales of riverine export of carbon, especially organic carbon, from land to sea. To attain their goal, the proponents will integrate geochemical measurements on the temporal and spatial changes in the composition of dissolved and particulate river loads combined with spatial and temporal data on relevant ecosystem, hydrologic, geologic, geomorphologic, and climatologic characteristics obtained from remote sensing and GIS mapping. The study will be conducted on six large river basins, namely the Brahmaputra, Congo, Ganges, Lena, Fraser, and Yangtze. This represents an integrated, multi-disciplinary project that focuses on an emerging topic in carbon cycling because processes occurring at the land/ocean boundary have not been adequately addressed to date. Lack of this information represents a glaring omission for marine scientists involved in establishing the carbon cycle of the ocean. As regards broader impacts, a traveling art exhibition based on the artwork of students living near their study sites in Siberia, Bangladesh, India, Canada, China, and Africa will be developed. The exhibition idea is based on their successful pilot program entitled 'My River, My Home' carried out on the Lena River. It is anticipated that the exhibit will engage local populations at the study sites as well as document the scientific and cultural aspects of the project to a broader public audience. In addition, the project represents a strong collaborative effort between scientists in the United States and colleagues in Russia, China, Canada, Bangladesh, the Republic and Democratic Republic of Congo and France. Two graduate students and one postdoc will be supported and trained as part of this project.

来自伍兹霍尔海洋研究所和伍兹霍尔研究中心的科学家将描述河流从陆地向海洋输出碳，特别是有机碳的来源、途径和时间尺度。为了实现他们的目标，倡议者将把溶解和颗粒河流负荷组成的时空变化的地球化学测量与遥感和地理信息系统制图获得的有关生态系统、水文、地质、地貌和气候特征的时空数据结合起来。这项研究将在六大河流流域进行，即雅鲁藏布江、刚果河、恒河、勒拿河、弗雷泽河和长江。这是一个综合的、多学科的项目，重点关注碳循环中的一个新兴主题，因为迄今为止，在陆地/海洋边界发生的过程还没有得到充分的解决。对于参与建立海洋碳循环的海洋科学家来说，缺乏这些信息是一个明显的遗漏。在更广泛的影响方面，将以居住在西伯利亚、孟加拉国、印度、加拿大、中国和非洲学习地点附近的学生的艺术作品为基础，举办巡回艺术展。这次展览的想法是基于他们在勒拿河上成功开展的名为“我的河，我的家”的试点项目。预计这次展览将吸引研究地点的当地居民，并向更广泛的公众展示该项目的科学和文化方面。此外，该项目代表了美国科学家与俄罗斯、中国、加拿大、孟加拉国、刚果共和国和民主共和国以及法国的同事之间的强有力合作努力。作为该项目的一部分，将支持和培训两名研究生和一名博士后。
