项目摘要

AbstractPI: Robert A. Bindschadler Proposal Number: 0732906Collaborative With: McPhee 0732804, Holland 0732869, Truffer 0732730, Stanton 0732926, Anandakrishnan 0732844 Title: Collaborative Research: IPY: Ocean-Ice Interaction in the Amundsen Sea Sector of West AntarcticaThe Office of Polar Programs, Antarctic Integrated and System Science Program has made this award to support an interdisciplinary study of the effects of the ocean on the stability of glacial ice in the most dynamic region the West Antarctic Ice Sheet, namely the Pine Island Glacier in the Amundsen Sea Embayment. The collaborative project builds on the knowledge gained by the highly successful West Antarctic Ice Sheet program and is being jointly sponsored with NASA. Recent observations indicate a significant ice loss, equivalent to 10% of the ongoing increase in sea-level rise, in this region. These changes are largest along the coast and propagate rapidly inland, indicating the critical impact of the ocean on ice sheet stability in the region. While a broad range of remote sensing and ground-based instrumentation is available to characterize changes of the ice surface and internal structure (deformation, ice motion, melt) and the shape of the underlying sediment and rock bed, instrumentation has yet to be successfully deployed for observing boundary layer processes of the ocean cavity which underlies the floating ice shelf and where rapid melting is apparently occurring. Innovative, mini ocean sensors that can be lowered through boreholes in the ice shelf (about 500 m thick) will be developed and deployed to automatically provide ocean profiling information over at least three years. Their data will be transmitted through a conducting cable frozen in the borehole to the surface where it will be further transmitted via satellite to a laboratory in the US. Geophysical and remote sensing methods (seismic, GPS, altimetry, stereo imaging, radar profiling) will be applied to map the geometry of the ice shelf, the shape of the sub ice-shelf cavity, the ice surface geometry and deformations within the glacial ice. To integrate the seismic, glaciological and oceanographic observations, a new 3-dimensional coupled ice-ocean model is being developed which will be the first of its kind. NASA is supporting satellite based research and the deployment of a robotic-camera system to explore the environment in the ocean cavity underlying the ice shelf and NSF is supporting all other aspects of this study. Broader impacts: This project is motivated by the potential societal impacts of rapid sea level rise and should result in critically needed improvements in characterizing and predicting the behavior of coupled ocean-ice systems. It is a contribution to the International Polar Year and was endorsed by the International Council for Science as a component of the "Multidisciplinary Study of the Amundsen Sea Embayment" proposal #258 of the honeycomb of endorsed IPY activities. The research involves substantial international partnerships with the British Antarctic Survey and the University of Bristol in the UK. The investigators will partner with the previously funded "Polar Palooza" education and outreach program in addition to undertaking a diverse set of outreach activities of their own. Eight graduate students and one undergraduate as well as one post doc will be integrated into this research project.
AbstractPI: Robert A. Bindschadler Proposal Number: 0732906Collaborative With: McPhee 0732804, Holland 0732869, Truffer 0732730, Stanton 0732926, Anandakrishnan 0732844 Title: Collaborative Research: IPY: Ocean-Ice Interaction in the Amundsen Sea Sector of West南极计划,南极综合和系统科学计划的南极病态已获得该奖项,以支持对海洋对冰川冰在最具动态的地区的稳定性的跨学科研究,即南极冰块西部,即在阿蒙德森海嵌入中的派恩岛冰川。 该协作项目基于非常成功的西南极冰盖计划所获得的知识,并由NASA共同赞助。 最近的观察结果表明,在该地区,海平面上升持续增长的10%占冰损的大量损失。这些变化在沿海地区最大,并迅速传播内陆,表明海洋对该地区的冰盖稳定性产生了关键影响。 虽然可以使用广泛的遥感和地面仪器来表征冰表面和内部结构的变化(变形,冰运动,融化)以及基础沉积物和岩石床的形状,但仪器尚未成功部署,以观察海洋腔的边界层过程,这些过程是浮冰和快速融化的层面,这显然是融化的。 可以开发并部署的创新的迷你海洋传感器可以通过冰架(约500 m厚)的钻孔降低,以在至少三年内自动提供海洋分析信息。 他们的数据将通过在钻孔中冷冻的电缆传输到表面,在那里将通过卫星进一步传输到美国的实验室。 地球物理和遥感方法(地震,GPS,高度测定,立体图,雷达分析)将用于绘制冰架的几何形状,亚冰架腔的形状,冰层表面几何形状和冰川冰内的变形。 为了整合地震,冰川和海洋学的观察,正在开发一种新的3维冰山模型,这将是同类的第一个。 NASA支持基于卫星的研究和机器人摄像机系统的部署,以探索冰架和NSF为基础的海洋腔中的环境支持本研究的所有其他方面。 更广泛的影响:该项目是由海平面快速上升的潜在社会影响所激发的,并应在表征和预测耦合海冰系统的行为方面迫切需要改善。 这是对国际极地年份的贡献,并得到了国际科学委员会的认可,这是“对阿蒙森海胚胎的多学科研究”的组成部分。 这项研究涉及与英国南极调查和英国布里斯托尔大学的实质性国际伙伴关系。 调查人员将与先前资助的“ Polar Palooza”教育和外展计划合作,除了自己进行各种外展活动外。 八名研究生和一名本科生以及一名邮政DOC将集成到该研究项目中。
