0742526 GoniAbstract Funds are provided for the PIs to carry out a multi-faceted, multi-disciplinary research towards understanding sediment and organic matter fluxes in the Fly River, Papua New Guinea. The work builds on previous study by the PIs working in the lower reaches of the Fly River River to understand sediment delivery and dispersal, and in the Fly delta and offshore clinoform to understand organic matter burial in the system. The work will test three related hypotheses, all important as the stated goals of the MARGINS' source-to-sink initiative: 1) that the Fly River transports, buries and sequesters a globally significant amount of organic carbon; 1) sediment exchange processes between channels and floodplains modulate biogeochemical fluxes, and 3) partial and full channel avulsions govern sediment and carbon accumulation across the distal floodplain. Field surveys and sampling and coring of the floodplains is planned, as are lab studies and modeling efforts at three different institutions.

0742526 GoniAbstract 为 PI 提供资金，以开展多方面、多学科的研究，以了解巴布亚新几内亚弗莱河的沉积物和有机物通量。这项工作建立在之前研究人员在弗莱河下游工作以了解沉积物输送和扩散的研究基础上，以及在弗莱河三角洲和近海斜坡上工作以了解系统中有机物埋藏情况的研究基础上。这项工作将测试三个相关的假设，这些假设对于 MARGINS 的“源到汇”倡议的既定目标都很重要：1）弗莱河运输、埋藏和封存了全球大量的有机碳； 1）河道和洪泛区之间的沉积物交换过程调节生物地球化学通量，3）部分和全部河道撕扯控制着远端洪泛区的沉积物和碳积累。计划对洪泛区进行实地调查、采样和取芯，以及三个不同机构的实验室研究和建模工作。
