The PI's are funded to study high-sedimentation rate cores from coastal back-barrier ponds and sink holes at three different sites on Cape Cod, Massachusetts, Apalachee Bay, Florida, and Grenada in the Caribbean to reconstruct a late Holocene hurricane frequency record. They will also use storm-surge models to examine the significance spatial and temporal patterns in hurricane-induced deposition and test potential climate forcing. Earlier data from Puerto Rico suggests specific trends in hurricane frequency, e.g., an increase in hurricane landfall during the past 300 years. Improving understanding of long-term trends in hurricane landfall statistics is important for understanding the socioeconomic impacts of hurricanes and future projections.Broader impacts of the study are strong: reconstructing the history of hurricane frequency/intensity in the study area with important implications for climate modeling and coastal zone management. Graduate student support is also included.

PI的资助研究高沉积速率的核心从沿海后障池和沉孔在三个不同的地点在科德角，马萨诸塞州，阿巴拉契亚湾，佛罗里达，格林纳达在加勒比海重建一个晚全新世飓风频率记录。他们还将使用风暴潮模型来研究飓风引起的沉积的重要性空间和时间模式，并测试潜在的气候强迫。来自波多黎各的早期数据显示了飓风频率的具体趋势，例如，在过去的300年里，飓风登陆的次数有所增加。加强对飓风登陆统计数据长期趋势的理解对于理解飓风的社会经济影响和未来预测非常重要。该研究的更广泛影响是强大的：重建研究区域飓风频率/强度的历史，对气候建模和沿海地区管理具有重要意义。研究生的支持也包括在内。
