0637108GiosanThis Small Grant for Exploratory Research (SGER) project will send the principal investigator Dr. Liviu Giosan and postdoctoral researcher Dr. Andrew Ashton from Woods Hole Oceanographic Institute to the Danube Delta region in Romania to survey the deposits of the recent disastrous Danube floods of 2005 and 2006. The U.S. researchers will study the sediment beds resulting from the 2005-2006 floods to obtain a good understanding of flood indicators in sediments of the delta. The deposits of the recent flood will be transformed and/or disturbed by physical and biological processes as time goes by, and as more time elapses, the deposits will be harder to clearly identify. Thus, the researchers intend to travel to the Danube Delta to conduct their research in Fall 2006.The PI is collaborating with several Romanian scientists who have experience in the Danube Delta. Drs. Iuliana Armas, Stefan Constantinescu and Alfred Vespremeanu-Stroe, the main collaborators, are members of the Faculty of Geography at the University of Bucharest. They have been monitoring the flood and will participate in the field research together with doctoral, master's and bachelor's degree students from the University of Bucharest. The Romanian team has worked with the PI to plan the proposed research.Intellectual Merit:The Danube River is the largest river in the Central and Southeastern Europe. Flood and drought hazards along the river directly affect 10 countries. The researchers involved in this project will survey the deposits of the recent disastrous Danube floods of 2005 and 2006. The survey will take place at strategic positions primarily at the apex of the Danube delta and secondarily on the river-dominated sector on the Black Sea continental shelf. Both of these locations integrate the signal of the entire Danube basin and provide the opportunity to extend the analysis to the longer period of the late Holocene, when the sea level change was not an important factor in sedimentation. During this time significant climatic intervals such as the Little Ice Age or Medieval Warm Period occurred, probably leading to changes in the river hydrology. Understanding the sedimentary markers of modern floods will provide the community with tools for this paleoreconstruction. It will also provide input parameters for modeling of the Danube discharge regime that will be undertaken in the future. In addition, in-depth understanding of the flood sedimentation of the Danube will contribute to the knowledge of floodplain and prodelta sedimentation and development.Broader Impact:The Danube Delta is an area of special ecological importance, which had not attracted much attention from U.S. researchers. The floods of 2005-2006 were devastating to the area, and better understanding of the flooding behavior of the river has both scientific and societal value. This project supports two U.S. junior researchers in a well-founded intellectual collaboration with international partners.

0637108 giosanthisthis探索性研究（SGER）项目将派遣主要研究员Liviu Giosan博士和博士后研究人员的Andrew Ashton博士安德鲁·阿什顿（Andrew Ashton）博士到罗马尼亚多瑙河地区的Danube Delta地区的Andrew Ashton Dr.对三角洲沉积物中的洪水指标有很好的了解。随着时间的流逝，最近的洪水的沉积物将被物理和生物学过程转化和/或打扰，并且随着时间的流逝，这些沉积物将很难清楚地识别。因此，研究人员打算在2006年秋季前往多瑙河三角洲进行研究。PI与几位在多瑙河三角洲有经验的罗马尼亚科学家合作。博士。 Iuliana Armas，Stefan Constantinescu和主要合作者Alfred Vespremeanu-Stroe是布加勒斯特大学地理学院的成员。他们一直在监视洪水，并将与布加勒斯特大学的博士，硕士和学士学位学生一起参加现场研究。罗马尼亚团队与PI合作计划了拟议的研究。智能优点：多瑙河是中欧和东南欧最大的河流。河流沿河的洪水和干旱危害直接影响10个国家。参与该项目的研究人员将调查2005年和2006年最近发生的灾难性多瑙河洪水的沉积物。该调查将主要在多瑙河三角洲的顶点处于战略位置，其次是在黑海大陆架上以河流为主的部门进行的。这两个位置都整合了整个多瑙河盆地的信号，并提供了将分析扩展到更长的全新世晚期的机会，当时海平面变化不是沉积中的重要因素。在此期间，发生了很大的气候间隔，例如小冰河时代或中世纪的温暖时期，可能导致河流水文学的变化。了解现代洪水的沉积标志物将为社区提供这种古reconlectustruction的工具。它还将提供未来将要进行的多瑙河放电制度建模的输入参数。此外，对多瑙河的洪水沉积的深入了解将有助于洪泛区和Prodelta沉积和发展的知识。Broader的影响：多瑙河三角洲是一个特别重要的重要性领域，并没有引起美国研究人员的很多关注。 2005 - 2006年的洪水对该地区造成了破坏，对河流的洪水行为的更好理解既具有科学和社会价值。该项目支持两名与国际合作伙伴建立良好的智力合作进行的美国初级研究人员。
