This project takes advantage of the major coastal extra-tropical storm, Hurricane Sandy that came ashore in New Jersey on November 6, 2012. The proposed research will evaluate the properties and processes in the coastal salt marshes immediately after and in the year following Sandy to compare with existing pre-storm data. The relationship of short-term hurricane induced flooding and sedimentation to marsh elevation change, accumulation rates of plants and dead material, and changes in soil and water chemistry will be determined for three salt marshes of the Delaware Estuary and three salt marshes of Barnegat Bay, New Jersey.This proposal addresses fundamental questions about the influences of major coastal storms on ecosystem structure and function. There are opportunities to directly observe effects of this severe disturbance on processes that have been monitored over time in the past with other funding. This proposal is a good fit for the RAPID funding mechanism because it addresses important and fundamental questions related to coastal marsh ecosystem dynamics, will enable new and additional sample collection and analyses, and is time-sensitive. It is critical to get plots re-established, baseline samples taken, and initial measurements made before the systems are further altered by the usual winter weather of this region. The prospect of future storms of this magnitude suggests the need to understand their effects on ecosystem dynamics as part of a new-normal for the East Coast. Information from this project about the impacts of Hurricane Sandy on local salt marshes will be of use to local wetland managers (e.g., U.S. Fish and Wildlife Service, Island Beach State Park) and to the coastal communities in the area. The information gained will also be extrapolated to predict future storm event effects, will serve as a case study applicable to other Atlantic coast wetlands, and will advance our understanding of storm effects on wetland ecosystem processes in general.

该项目利用了 2012 年 11 月 6 日在新泽西州登陆的主要沿海温带风暴桑迪飓风。拟议的研究将评估桑迪飓风过后和翌年沿海盐沼的特性和过程，以评估沿海盐沼的特性和过程。与现有的风暴前数据进行比较。将确定特拉华河口的三个盐沼和巴尼加特湾的三个盐沼的短期飓风引发的洪水和沉积与沼泽海拔变化、植物和死亡物质的积累率以及土壤和水化学变化的关系。新泽西州。该提案解决了主要沿海风暴对生态系统结构和功能影响的基本问题。有机会直接观察这种严重干扰对过去通过其他资金长期监测的过程的影响。该提案非常适合 RAPID 资助机制，因为它解决了与沿海沼泽生态系统动态相关的重要和基本问题，将实现新的和额外的样本收集和分析，并且具有时间敏感性。在系统因该地区通常的冬季天气进一步改变之前，重新绘制地块、采集基线样本并进行初步测量至关重要。 未来出现如此规模的风暴的前景表明，有必要了解其对生态系统动态的影响，作为东海岸新常态的一部分。该项目有关桑迪飓风对当地盐沼影响的信息将供当地湿地管理者（例如美国鱼类和野生动物管理局、岛屿海滩州立公园）以及该地区的沿海社区使用。获得的信息还将被推断以预测未来风暴事件的影响，将作为适用于其他大西洋沿岸湿地的案例研究，并将增进我们对风暴对湿地生态系统过程的总体影响的理解。
