The opportunistic collection of sediment cores before and after the landfall of Hurricane Ian in Florida provided the opportunity to assess potential impact(s) of the storm on the seafloor of Boca Ciega Bay in the Tampa Bay area. In late September of 2022, Hurricane Ian developed into a category 4 hurricane with the eye making landfall in Fort Myers, Florida. The range of this hurricane, although distant, stretched far enough to reach Boca Ciega Bay in the Tampa Bay area. Offshore winds pushed water out of Tampa Bay with tides ~7 feet lower than predicted, exposing large areas of the seafloor. The resurgence of the water created a reverse storm surge, with the potential for sediment resuspension, transport, and deposition within the bay. Due to the rapid drain and flood of the bay waters, sediments can be transported from the high energy water movement from one place to another. This transport of sediments can alter the bathymetry of the bay along with changing the benthic environment such as covering seagrass beds. Initial visual comparison of pre-storm and post-storm sediment cores displayed a thick sedimentary layer (~5-10cm) that likely accumulated during the storm event. The purpose of this project is to distinguish a signature left by this event through texture and composition analyses of sediment cores and surface sediment samples, as well as observing radioisotope and trace element signatures. The use of these processes will serve as a guideline for the environment's reaction to similar weathering processes in the future.
