Collaborative Research: Formation, Reworking and Accumulation of Sedimentary Deposits, Waipaoa River Shelf, New Zealand

沃尔什/哈里斯/奥格斯顿基金被提供给私人投资机构，以收集关于怀保阿大陆架的数据，以该地区以前的工作成果为基础。这项研究的目的是使用底部三脚架记录与沿一条明显的输送路线的沉积物过程有关的数据，并收集岩芯，并在某些地点测量临界剪应力。这项研究将考虑在前一次研究中收集岩心的地点，研究的一个主要重点是比较不同年份收集的岩心，以确定是否已经沉积了更多的岩层。还将在这些地点进行放射化学研究，以帮助量化沉积物的沉积情况。底部的三脚架将沿着架子上的一条线放置，靠近搁板断裂处，并放在上层看似是运输通道或沉积地点的区域。三脚架将部署一年。这项研究的第三个组成部分是建立和使用一个模型，其中包括“区域”内客观的后播沉积事件。这项研究包括学生的参与和培训，并将有助于理解陆架过程与由此形成的地层结构的关系，这是地层学中的一项重要挑战，并有可能有助于未来的资源勘探。

Walsh/Harris/Ogston Funds are provided to the PIs to collect data on the Waipaoa continental shelf to build on results of prior work in the area. The objective of the study is to use bottom tripods to record data relevant to sediment processes along an apparent transport route, and to collect cores and, at some sites, measure critical shear-stress. The study will consider locations where cores were collected during a prior study, and one major focus of the study is the comparison of cores collected in different years to determine if additional layers have been deposited. Radiochemical studies will also be undertaken at these sites to help quantify the deposition of sediments. The bottom tripods will be placed along a line on the shelf, near the shelf break and on the upper rise in areas that appear to be transport pathways or sites of deposition. The tripods would be deployed for a year. The third component of the study is the creation and use of a model with the objective hindcast sedimentation events in the area. The study includes student involvement and training and will lead to an understanding of the relationship of shelfal processes to resultant stratigraphic architecture which is an important challenge in stratigraphy and has the potential to aid exploration for resources in the future.
