This RAPID project will study how tropical storms disperse sediments and any associated pollutants around impacted coastal bays. Specifically, it will study the impacts of the storm surge and associated flood deposit left by Hurricane Ian (September 2022) in Estero, Naples and Dollar Bay, Florida, and fringing mangroves. The study will compare the impact of this storm on urbanized estuaries vs. natural and wildlife areas. The project Broader Impacts include an improved understanding of how tropical storms impact the sustainability of fragile coastal systems in a rapidly changing climate regime. Educational Broader Impacts include field and laboratory research experience for undergraduate and graduate students and a postdoctoral fellow. The project will assess storm impacts by collecting sediment cores throughout the navigable portions of the bay systems, as well as fringing mangrove systems. Using a combination of visual observations, x-radiography of the cores and physical sedimentology of the sediment within the cores, the storm layer stratigraphy will be assessed. In addition, sediment samples will be analyzed for Total Mercury and Persistent Organic Pollutants or POPs (such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs)). A series of maps will be generated showing the thickness of the storm layer, the mean grain size of the associated sediment, and the contaminant loads for each of the respective contaminants assessed.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个快速项目将研究热带风暴如何分散受影响的沿海海湾周围的沉积物和任何相关污染物。具体地说，它将研究飓风伊恩(2022年9月)在佛罗里达州埃斯特罗、那不勒斯和美元湾以及边缘红树林留下的风暴潮和相关洪水沉积的影响。这项研究将比较这场风暴对城市化河口与自然和野生动植物地区的影响。该项目更广泛的影响包括更好地了解热带风暴如何在快速变化的气候制度下影响脆弱的沿海系统的可持续性。更广泛的教育影响包括本科生和研究生以及博士后的实地和实验室研究经验。该项目将通过在海湾系统的通航部分以及红树林系统的边缘收集沉积物岩心来评估风暴影响。结合目视观测、岩芯x射线照相和岩芯内沉积物的物理沉积学，将对风暴层地层学进行评估。此外，将对沉积物样本进行总汞和持久性有机污染物或持久性有机污染物(如多环芳烃和多氯联苯)的分析。将生成一系列地图，显示风暴层的厚度、相关沉积物的平均粒度以及所评估的每种污染物的污染物负荷。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
