SGER: Stratigraphy, Sedimentology, Microfossil Content and Preservation of Hurricane Ike Storm Surge Deposits in Southeast Texas and Southwest Louisiana.

该项目将研究飓风艾克在德克萨斯州东南部和路易斯安那州西南部的风暴潮的影响。具体地说，这项研究将检查由潮汐产生的沉积物，以及它们在沿海环境中的分布。通过将这些沉积物与飓风卡特里娜和丽塔的类似沉积物进行比较，该项目将提供对这些极端事件在重塑沿海环境方面的重要性的定量估计。该项目将从飓风登陆前已经取样的湖泊中收集沉积物岩心。对飓风前后沉积物的比较将提供一幅非常清晰的图片，在这一证据可能被生物扰动掩盖之前，沉积物和微化石被输送到湖床上。这项研究的结果将有助于更好地了解风暴潮对沿海环境的影响，包括更可靠地评估飓风袭击的重现间隔和相关的飓风风险，改进飓风袭击高危海岸线的地理变异性的记录，以及记录史前飓风活动，可用于评估飓风的频率和强度与气候变化之间的关系。

This project will study the effects of the storm surge of Hurricane Ike in southeast Texas and southwest Louisiana. Specifically, the research will examine the sediments resulting from the surge, and their distribution within the coastal environment. By comparing these deposits to similar sediments from Hurricanes Katrina and Rita, this project will provide quantitative estimates of the significance of these extreme events in reshaping the coastal environment. The project will collect sediment cores from lakes that had already been sampled prior to the hurricane landfall. Comparison of pre- and post-hurricane deposits will provide a very clear picture of the exact nature of sediments and microfossils that were transported onto the lake beds, before this evidence is potentially obscured by bioturbation. It will also provide a baseline for identifying hurricane deposits that have occurred in the region over the past several hundred years.The results of the study will contribute to a better understanding of the effects of storm surge on the coastal environment.These include more reliable assessments of the recurrence interval of hurricane strikes and associated hurricane risk, an improved record of the the geographic variability of hurricane strikes along at-risk coastlines; and the documentation of prehistoric hurricane activity that can be used to assess the relationship between the frequency and strength of hurricanes and climate change.
