This project will explore the sources and fates of organic matter as it travels from source to sink in the Waipaoa Rivers system in New Zealand. Because the organic matter content, age, and isotopic character are influenced by sediment transport processes and rates, this information provides valuable insight into the movement of sediment through the system. The project will provide an independent view on sediment fluxes and residence times in various environments from the sediment source to offshore depocenters. A large fraction of the terrestrial organic matter delivered to the sea comes from small rivers on active continental margins and studies of this subject are sparse. This type of study was identified as important by a MARGINS program review committee. The S2S initiative with MARGINS program offers an appropriate venue to conduct such research in a holistic manner.The project will involve graduate and undergraduate students. It also involves substantial international cooperation with New Zealand scientists. The study will use and develop biogeochemical tools to assess the transport and burial of organic matter in a source to sink system. The study of storage and burial of organic carbon is of importance to understanding regional and global carbon cycling and will impact other climate, sea-level and sediment transport studies

这个项目将探索有机物质的来源和命运，因为它从源头到汇在新西兰怀帕阿河系统。由于有机质含量、年龄和同位素特征受沉积物输运过程和速率的影响，这些信息为沉积物在系统中的运动提供了有价值的见解。该项目将提供从沉积物源到近海沉积中心的各种环境中沉积物通量和停留时间的独立视图。输送到海洋的陆相有机质的很大一部分来自活跃大陆边缘的小河，而这方面的研究很少。这种类型的研究被一个边际项目审查委员会认定为重要的。S2S倡议与边际计划提供了一个适当的场所，以全面的方式进行此类研究。该项目将涉及研究生和本科生。它还涉及与新西兰科学家的大量国际合作。该研究将使用和开发生物地球化学工具来评估从源到汇系统中有机物的运输和埋藏。有机碳的储存和埋藏研究对于了解区域和全球碳循环具有重要意义，并将影响其他气候、海平面和沉积物运输研究
