项目摘要
Intellectual Merit: The PI hypothesizes that bedforms found in the Central and Joides troughs can be interpreted as having been formed by rapid retreat, and possible collapse of an ice stream that occupied this area. To test this hypothesis, the PI proposes to conduct a detailed marine geological and geophysical survey of Central and Joides Troughs in the western Ross Sea. This project will bridge gaps between the small and isolated areas previously surveyed and will acquire a detailed sedimentological record of the retreating grounding line. The PI will reconstruct the retreat history of the Central and Joides troughs to century-scale resolution using radiocarbon dating methods and by looking at geomorphic features that are formed at regular time intervals. Existing multibeam, deep tow side-scan sonar, and core data will provide a framework for this research. The western Ross Sea is an ideal study area to investigate a single ice stream and the dynamics controlling its stability, including interactions between both East and West Antarctic Ice Sheets. Broader impacts: This proposal includes a post-doc, a graduate and two undergraduate students. The post-doc is involved with teaching an in-service K-12 teacher development and training course at Rice University for high-need teachers with a focus on curriculum enhancement. The project fosters collaboration for the PI and students with researchers at Louisiana State University and international colleagues at the Institute for Paleobiology at the Polish Academy of Sciences. The results from this project could lead to a better understanding of ice sheet and ice stream stability. This project will yield implications for society's understanding of climate change, as this work improves understanding of the behavior of ice sheets and their links to global climate.
智力优势:PI假设,在中央和Joides槽中发现的底形可以被解释为是由快速撤退形成的,并且可能是占据这一地区的冰流的崩溃。为了验证这一假设,PI建议对罗斯海西部的中央和Joides槽进行详细的海洋地质和地球物理调查。该项目将弥补先前勘测的小的孤立地区之间的差距,并将获得后退接地线的详细沉积记录。PI将使用放射性碳测年方法并通过观察定期形成的地貌特征,重建中央槽和Joides槽的退缩历史,以达到世纪尺度的分辨率。现有的多波束、深拖侧扫声纳和岩心数据将为这项研究提供一个框架。罗斯海西部是研究单一冰流及其控制其稳定性的动力学的理想研究区域,包括东南极冰盖和西南极冰盖之间的相互作用。更广泛的影响:该提案包括一名博士后,一名研究生和两名本科生。博士后参与教学在职K-12教师发展和培训课程在赖斯大学的高需求的教师,重点是课程的增强。该项目促进了PI和学生与路易斯安那州立大学研究人员和波兰科学院古生物学研究所的国际同事的合作。该项目的结果可以更好地了解冰盖和冰流稳定性。该项目将对社会对气候变化的理解产生影响,因为这项工作提高了对冰盖行为及其与全球气候联系的理解。
