Rapid Grant: Collaborative Investigations of the Impact of Superstorm Sandy on the South Shore of Long Island

超级风暴桑迪对纽约和新泽西的海岸线造成了历史性的影响。这一合作快速反应项目将评估超级风暴桑迪对河口和浅海沿岸环境的影响，重点是西湾和牙买加湾。该项目将利用PIs在风暴之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研究人员计划的相关野外项目。先前采样的地点将重新用于沉积物采样（重力和箱形岩心，抓取样本）以及结构和地球化学示踪剂分析。多波束测深将在以前调查过的地区收集，并将覆盖一个新的退潮三角洲系统和较小的河口水道。这些数据将与输沙指标和碎屑场制图相结合，评估超级风暴“桑迪”期间泥沙输沙的途径和机制。这项工作将有助于更好地理解浅层海底对极端风暴的反应，并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研究。保护区计划与区域伙伴（南岸河口保护区、飞溅行动）合作，并参与公众宣传。

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.
