This proposal requests funds for a Small Exploratory Research (SGER) proposal to support a rapid-response study to isolate and evaluate the sedimentologic and geomorphic impact of Hurricane Michelle on the coastal systems of Andros Island, Bahamas using ultra-high resolution remote sensing data calibrated by field observations. Pre-storm ultra-high resolution remote sensing data are available to the PI and serve as a baseline for comparison. Differences between the pre-storm data and the post-storm data acquired through this funding will serve as focal points for a week of field work that will characterize the geomorphic and sedimentologic attributes of the changes. By integrating the map patterns of change and their sedimentologic characteristics, we will develop models for the impact of major storms on the stability of coastal systems, including but not limited to the shoreline. These changes will also be compared with historical changes (~60 year) recently documented by the PI.Results of this study will have implications for the stability of shorelines and entire coastal systems landward of the shoreline, the parameters that control the evolution of these systems, and the interpretation of the geologic record of tidal flats. The need for rapid acquisition of the ultra-high resolution remote sensing data and the field validation to assess the hurricane's impact make this proposal appropriate for an SGER.

该提案要求为一项小型探索性研究项目提供资金，以支持一项快速反应研究，该研究利用经实地观测校准的超高分辨率遥感数据，隔离和评估飓风米歇尔对巴哈马安德罗斯岛沿海系统的沉积和地貌影响。风暴前的超高分辨率遥感数据可以提供给PI，并作为比较的基线。通过这笔资金获得的风暴前数据和风暴后数据之间的差异将成为为期一周的实地工作的焦点，这些工作将描述变化的地貌和沉积学属性。通过综合地图变化模式及其沉积学特征，我们将开发主要风暴对海岸系统稳定性的影响模型，包括但不限于海岸线。这些变化还将与国际地球物理研究所最近记录的历史变化(~60年)进行比较。这项研究的结果将对海岸线和整个海岸体系的稳定性、控制这些体系演化的参数以及潮滩地质记录的解释具有重要意义。由于需要快速获取超高分辨率遥感数据并进行实地验证以评估飓风的影响，因此这一建议适用于SGER。
