SGER: Sedimentologic and Geomorphic Response of a Tidal Flat System to Hurricane Michelle: Andros Island, Bahamas

本提案要求为小型探索性研究（SGER）提案提供资金，以支持一项快速响应研究，利用现场观测校准的超高分辨率遥感数据，分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学和地貌影响。风暴前的超高分辨率遥感数据可提供给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一个星期实地工作的重点，该工作将描述变化的地貌和沉积属性。通过整合变化的地图模式及其沉积学特征，我们将开发大风暴对海岸系统稳定性影响的模型，包括但不限于海岸线。这些变化还将与PI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系统的稳定性、控制这些系统演变的参数以及对潮滩地质记录的解释产生影响。由于需要快速获取超高分辨率遥感数据和现场验证以评估飓风的影响，因此该建议适合SGER。

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.
