Superstorm Sandy had a historic impact on the New York and New Jersey coastlines. This collaborative Rapid Response project will assess the effect of Superstorm Sandy in estuarine and shallow coastal environments, focusing on the Western Bays and Jamaica Bay. The project will leverage pre-existing geophysical and sedimentological data collected by the PIs prior to the storm, and will complement a related field program planned by investigators at the University of Texas Institute for Geophysics. Previously sampled sites will be reoccupied for sediment sampling (gravity and box cores, grab samples) and textural and geochemical tracer analyses. Multibeam bathymetry will be collected in previously surveyed areas and will cover a new ebb-tidal delta system and smaller estuarine channels. These data will be combined with transport indicator and debris field mapping to evaluate the pathways and mechanisms of sediment transport during Superstorm Sandy.This work will lead to a better understanding of the response of the shallow seafloor to extreme storms and will help to constrain the regional sediment budget, a potentially important consideration in the rebuilding process. Graduate and undergraduate students will be involved in the research. The PIs plan to work with regional partners (South Shore Estuary Reserve, Operation Splash) and engage in public outreach.

超级风暴桑迪对纽约和新泽西海岸线产生了历史性的影响。这一合作快速反应项目将评估超级风暴桑迪在河口和浅海环境中的影响，重点是西湾和牙买加海湾。该项目将利用PIS在风暴之前收集的预先存在的地球物理和沉积学数据，并将补充德克萨斯大学地球物理研究所研究人员计划的相关实地项目。以前的采样点将被重新占用，用于沉积物采样(重力岩心和盒子岩心、抓取样品)以及纹理和地球化学示踪分析。多波束测深将在以前调查的地区收集，并将覆盖一个新的落潮三角洲系统和较小的河口航道。这些数据将与搬运指标和碎屑场图结合起来，以评估超级风暴桑德期间沉积物搬运的路径和机制。这项工作将有助于更好地了解浅海海底对极端风暴的反应，并将有助于限制区域沉积物收支，这可能是重建进程中的一个重要考虑因素。研究生和本科生将参与这项研究。投资促进机构计划与区域伙伴(南岸河口保护区、飞溅行动)合作，并开展公众宣传活动。
