RAPID: Impacts of Tropical Storm Debby in Apalachee Bay

热带风暴黛比(2012年6月24日至26日)是佛罗里达州阿帕拉奇湾的海岸屏障Bald Point 15年来的一次事件。由于风暴期间的涌浪高达1.8米，降雨量高达0.5米，洪水和洪水泛滥可能会对景观造成重大影响。这一快速反应项目将利用首席调查员、伍兹霍尔海洋研究所的一名科学家在这一领域已经开展的大量工作，描述位于Bald Point的TS Debby的地貌和沉积学特征。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/淤积。将从洗涤器表面和浅的、后阻挡岩芯收集沉积物样本，以进行质地和微化石分析。这项工作将有助于校准和验证以前根据Bald Point的屏障后地层学生成的热带风暴频率记录。该项目将使人们更好地了解墨西哥湾东北部地区强风暴的影响和历史频率。世界卫生组织REU项目的一名博士后研究员和一名本科生将得到支持。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的网站广泛提供。

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.
