RAPID: Impacts of Tropical Storm Debby in Apalachee Bay

热带风暴黛比（2012年6月24日至26日）是佛罗里达州阿巴拉契亚湾海岸屏障Bald Point的15年一遇事件。风暴期间的涌浪高达1.8米，降雨量为0.5米，洪水和过冲可能对景观造成重大影响。这一快速反应项目将利用伍兹霍尔海洋研究所的科学家、首席调查员在这一领域已经开展的大量工作，描述秃角TS Debby的地貌和沉积特征。风暴前收集的激光雷达将与风暴后的全站仪测量进行比较，以量化净侵蚀/堆积。将从冲刷面和浅的障壁后岩心收集沉积物样品，用于结构和微体化石分析。这项工作将有助于校准和验证以前生成的热带风暴频率记录的基础上秃头点的后障地层。该项目将导致更好地了解墨西哥湾东北部沿海地区严重风暴的影响和历史频率。一名博士后研究员和一名来自WHOI REU项目的本科生将得到支持。该项目的结果将传达给沿海管理团体和公众。数据将通过世界卫生组织海岸系统小组网站广泛提供。

Tropical Storm Debby (June 24-26, 2012) was a 1 in 15 year event for Bald Point, a coastal barrier in Apalachee Bay, FL. With as much as 1.8 m of surge and 0.5 m of rainfall during the storm, significant impacts on the landscape due to flooding and overwash are likely. This Rapid Response project will characterize the geomorphic and sedimentological signature of TS Debby at Bald Point, leveraging substantial work already conducted in this area by the principal investigator, a scientist at the Woods Hole Oceanographic Institution. LiDAR collected before the storm will be compared to post-storm total station surveys to quantify net erosion/accretion. Sediment samples from washover surfaces and shallow, backbarrier cores will be collected for textural and microfossil analyses. This work will help to calibrate and verify previously generated records of tropical storm frequency based on Bald Point's backbarrier stratigraphy. The project will lead to a better understanding of the impacts and historical frequency of severe storms in the northeastern Gulf Coast region. A post-doctoral researcher and an undergraduate student from WHOI's REU program will be supported. Results of the project will be communicated to coastal management groups and the general public. Data will be made broadly available through the WHOI Coastal Systems Group website.
