Funds will be provided to investigate sedimentation processes in the mixed siliciclastic carbonate slope and basin environment in the Gulf of Papua as a part of the integrated source-to-sink experiment at the Fly River-Gulf of Papua focus site of MARGINS. Through the use of detailed acoustic surveys and seabed and water column sampling the proposers will estimate sediment fluxes and transport pathways from the shelf edge and carbonate reef margins to the ultimate sinks of the Ashmore and Pandora troughs over the last interglacial cycle. The work will lead to an understanding of the history of sediment accumulation on the continental slope and the deep ocean for the mixed system as well as sediment fluxes and transport mechanisms by identifying timing and geometry of deposition in the Gulf. The ultimate objective is to develop a model for mixed carbonate-siliciclastic deposition.

将提供资金调查巴布亚湾混合硅质碳酸盐斜坡和盆地环境的沉积过程，作为 MARGINS 弗莱河-巴布亚湾焦点地点综合源-汇实验的一部分。通过使用详细的声学调查以及海底和水柱采样，提议者将估计最后一个间冰期周期从陆架边缘和碳酸盐礁边缘到阿什莫尔和潘多拉海槽最终汇的沉积物通量和传输路径。这项工作将通过确定海湾沉积的时间和几何形状，了解混合系统的大陆坡和深海沉积物积累的历史，以及沉积物通量和运输机制。最终目标是开发混合碳酸盐-硅质碎屑沉积的模型。
