Collaborative Research: Late Quaternary Siliciclastic and Carbonate Sediments and Sediment Fluxes on the Slopes and Basin Floors of the Ashmore and Pandora Troughs, Gulf of PNG

将提供资金调查巴布亚海湾混合硅屑碳酸盐斜坡和盆地环境中的沉积过程，这是在边缘的飞河-巴布亚海湾重点地点进行的从源到汇的综合实验的一部分。通过使用详细的声学调查以及海床和水柱采样，建议者将估计上一个间冰期周期中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下沉的沉积物通量和输送路径。这项工作将通过确定墨西哥湾的沉积时间和几何形状，使人们了解混合系统在大陆斜坡和深海沉积的历史，以及沉积物的通量和输送机制。最终目的是开发一种碳酸盐-硅屑混合沉积模式。

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.
