项目摘要

"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."Tidal marshes must grow vertically to keep pace with sea level rise, or risk permanent flooding. This research focuses on the processes that regulate vertical accretion in coastal marshes. These processes are tightly interconnected and are influenced by changes in climate and land use. As suspended sediment from watersheds declines, the projected increase in the rate of sea level rise put into question the ability of marshes to keep pace with rising sea levels. This project will examine how marsh plant production, rates of sediment delivery and changes in marsh surface elevation vary spatially in the Delaware River Estuary, a large mid-Atlantic estuarine system. Field experiments will also be used to determine how both tidal freshwater and salt marsh plant production and sediment delivery respond to changing sea levels and salinity. This will lead to a more predictive understanding of ecosystem responses to climate change, a major challenge that is of interest to scientists, land managers and planners, and the general public. Villanova University is a primarily undergraduate institution with solid commitment and history of educating undergraduate students through active involvement in research. In this case, two students a year will participate in a summer internship to learn techniques, design and conduct their own research project, and learn about other fields of study from active researchers. Focused recruitment of women and minorities will increase involvement of underrepresented groups in the sciences. Additional undergraduate student involvement in the proposed research will be attained through employment and Senior Thesis research credits, with results incorporated into several courses. Results will also be disseminated in the scientific literature, through talks at international scientific meetings, and to managers and stakeholders in the Delaware River and other coastal regions.
“该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。“潮汐沼泽必须垂直生长,以跟上海平面上升的步伐,否则就有永久性洪水的危险。这项研究的重点是在沿海沼泽调节垂直加积的过程。这些过程紧密相连,并受到气候和土地使用变化的影响。随着流域的悬浮沉积物减少,海平面上升速度的预计增加使人们对沼泽地跟上海平面上升速度的能力产生疑问。本项目将研究如何沼泽植物生产,沉积物输送率和沼泽表面高程的变化在空间上变化的特拉华州河口,一个大的中大西洋河口系统。还将利用实地实验来确定潮汐淡水和盐沼植物的生产和沉积物的输送如何对海平面和盐度的变化作出反应。这将导致对生态系统对气候变化的反应有更有预见性的理解,这是科学家、土地管理者和规划者以及公众感兴趣的一个重大挑战。维拉诺瓦大学是一所主要的本科院校,通过积极参与研究,具有坚定的承诺和教育本科生的历史。在这种情况下,每年有两名学生将参加暑期实习,学习技术,设计和进行自己的研究项目,并从活跃的研究人员那里了解其他研究领域。重点招聘妇女和少数民族将增加代表性不足的群体在科学领域的参与。额外的本科生参与拟议的研究将通过就业和高级论文研究学分,与结果纳入几门课程实现。研究结果还将通过在国际科学会议上的演讲在科学文献中传播,并传播给特拉华州河和其他沿海地区的管理人员和利益相关者。
