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。这一合作性快速反应项目将评估超级风暴桑迪对河口和浅海岸环境的影响，重点是西海湾和牙买加湾。该项目将利用PI在风暴前收集的现有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调查人员计划的相关实地项目。将重新占用以前取样的地点进行沉积物取样（重力取样和箱式取样、抓取取样）以及结构和地球化学示踪物分析。将在以前勘测的地区收集多波束测深数据，并将覆盖一个新的落潮三角洲系统和较小的河口水道。这些数据将与迁移指标和碎片场测绘相结合，以评价超级风暴桑迪期间沉积物迁移的路径和机制，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预算，这是重建过程中一个潜在的重要考虑因素。研究生和本科生将参与这项研究。PI计划与区域合作伙伴（南海岸河口保护区，飞溅行动）合作，并参与公共宣传。
