US-GERMANY workshop and joined field survey in the Arctic: Initiating a new collaboration with the COPER group (Alfred-Wegener-Institute) through a joined field survey.

该提案要求PI Stark和一名美国研究生参加即将到来的COPER（沿海永久冻土侵蚀，有机碳和营养物质释放到北极近岸地区，在德国波茨坦阿尔弗雷德-韦格纳研究所）对南波弗特海进行实地考察，并进行地质技术现场分析和沉积物采样，作为对预定的地貌学的补充。COPER群的沉积学、地质和地球化学调查。拟议的研究、合作和后续的研究工作将有助于填补关于北极海岸侵蚀和北极海岸线长期发展的知识空白。研究结果将改进对气候变化对北极影响的评估，以及制定保护环境和栖息地的对策。获得的经验会转移到PI Stark身上吗？沿海和海洋岩土工程课程，并将使学生意识到极地沿海岩土工程的新兴领域。拟议的合作工作将扩大对极地沿海地区的地质技术调查战略和侵蚀过程的了解，也将适用于工业目的或其他研究问题，并可能为在沿海极地地区进行更具成本效益和时间效益的地质技术调查铺平道路。气候变化及其导致的极地变化是科学、工程和社会最具挑战性和公认的现代问题之一。永久冻土的快速变化当然是最紧迫的问题之一，包括对海岸沉积物物理和岩土性质的影响，以及由此产生的海岸侵蚀后果。然而，控制北极海岸侵蚀的过程仍然知之甚少。其中一个潜在影响北极海岸侵蚀的因素，在以前的研究中还没有得到解决，那就是随着永久冻土水平的变化，近岸地区沉积物的岩土力学性质变化的影响。Hugues Lantuit博士是COPER小组（沿海永久冻土侵蚀，有机碳和营养物质释放到北极近岸地区，在德国波茨坦阿尔弗雷德-韦格纳研究所）的首席科学家，他已经认识到COPER研究中的这一知识差距，并开始与PI博士Nina Stark进行讨论，Nina博士是弗吉尼亚理工大学土木与环境工程助理教授，专门从事沿海地区的岩土工程野外测量。Lantuit将在考察期间提供基础设施和支持，共同监督美国研究生，并分享COPER数据，用于调查计划和随后的联合出版物。该数据集将通过对样品的后续测试和加入的出版物确保长期合作，并将作为一项更大的研究的概念证明，旨在对北极近岸地区进行有关海岸侵蚀的岩土技术调查。这项提议的工作还将为美国研究生提供对北极和国际研究的见解，并可能为极地沿海环境的岩土工程调查铺平道路。未来的研究重点。

a non-technical explanation This proposal requests travel funds for PI Stark and an U.S. graduate student to join the upcoming COPER (Coastal permafrost erosion, organic carbon and nutrient release to the Arctic nearshore zone, at the Alfred-Wegener-Institute in Potsdam, Germany) field expedition to the Southern Beaufort Sea, and conduct geotechnical in-situ profiling and sampling of sediment for following geotechnical laboratory experiments as a complement to the scheduled geomorphological, sedimentological, geological and geochemical investigations of the COPER group. The proposed study, collaboration and following research efforts will contribute to fill the gaps of knowledge regarding coastal erosion in the Arctic and long-term development of Arctic coastlines. The results will improve the assessments of impacts of climate change on the Arctic, and the development of countermeasures to secure environments and habitats. The gained experiences will be transferred into PI Stark?s Coastal and Marine Geotechnics classes, and will make students aware of the emerging field of coastal geotechnical engineering in the polar regions.a technical description The proposed collaborative work will widen the knowledge of geotechnical survey strategies and erosion processes in polar coastal zones, will be applicable also for industrial purposes or other research questions, and might pave the way for more cost- and time-efficient geotechnical surveys in the coastal polar zones.Climate change and the resulting change of the polar regions is one of the most challenging and recognized modern issues for sciences, engineering, as well as society. Rapid changes in the permafrost are certainly one of the most pressing issues, including the impact on physical and geotechnical coastal sediment properties, and the resulting consequences for coastal erosion. Nevertheless, the processes governing Arctic coastal erosion are still poorly understood. One of the factors that potentially influences coastal erosion in the Arctic, but has not been addressed in previous studies, is the impact of changes in geotechnical properties ofthe sediments in the nearshore zone following variations in the permafrost level. Dr. Hugues Lantuit, chief scientist of the COPER group (Coastal permafrost erosion, organic carbon and nutrient release to the Arctic nearshore zone, at the Alfred-Wegener-Institute in Potsdam,Germany) has recognized this gap of knowledge within the COPER studies, and initiated discussions with PI Dr. Nina Stark, assistant professor in Civil and Environmental Engineering at Virginia Tech, who is specialized on geotechnical field surveying in coastal zones. Lantuit will provide infrastructure and support during the expedition, co-supervise the U.S. graduate student, and share COPER data for survey planning and following joined publications. The data set will secure long-term collaborations via following testing of the samples and joined publications, and will serve as a proof-of-concept for a larger study aiming for the geotechnical investigation of the Arctic nearshore zone with regard to coastal erosion. The proposed work will also allow insights into Arctic and international research for a U.S. graduate student, and will possibly pave the way to make geotechnical investigations of polar coastal environments one of PI Stark?s future research foci.
