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.

这个快速的项目将研究热带风暴如何分散沉积物以及受影响的沿海海湾周围的任何相关污染物。具体来说，它将研究伊恩（Ian）飓风（2022年9月）在埃斯特罗（Estero），那不勒斯和佛罗里达州欧元湾（Dollar Bay）和边缘成山的影响。该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对热带风暴如何影响脆弱的沿海系统在快速变化的气候制度中的可持续性的了解。教育更广泛的影响包括针对本科生和研究生的实地和实验室研究经验以及博士后研究员。该项目将通过在湾系统的可通航部分以及边缘红树林系统中收集沉积物核来评估风暴的影响。使用视觉观测，核心核心的X射线照相和核心沉积物的物理沉积学，将评估风暴层地层。此外，将分析沉积物样品的总汞和持续性有机污染物或POP（例如多环芳烃（PAHS）和多氯联苯（PCB））。将生成一系列地图，显示暴风雨层的厚度，相关沉积物的平均晶粒尺寸以及所评估的每种污染物的污染物载荷。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来通过评估来获得支持的。
