项目摘要

The Amundsen Sea, in the remote Pacific sector of the Southern Ocean, is one of the least well studied Antarctic continental shelf regions. It shares characteristics in common with other Antarctic ice shelf regions, but exhibits unique aspects also. The Amundsen Sea Polynya (ASP), an open region at the base of several of the terminal glaciers draining the West Antarctic Ice sheet exhibits: 1) large intrusions of heat delivered from the warming modified circumpolar deep water (mCDW) rising up onto the continental shelf, 2) the fastest melting ice sheets in Antarctica, 3) the most productive coastal polynya (161 g C m-2) together with a significant atmospheric CO2 sink, and 4) some of the most rapidly declining regions of seasonal off-shore sea ice on Earth. Following on from an earlier oceanographic field program, the Amundsen Sea Polynya International Research Expedition (ASPIRE; 2011), this study seeks to better synthesize and model the relative contributions of both physical ocean-ice linkages and biological production and carbon export terms and to compare these with other circumpolar Antarctic regions. A central feature will be the use of a regionally coupled physical-biogeochemical model to follow the dynamics of the large phytoplankton blooms that occur annually in the Amundsen Sea Polyna. This study will provides a means to locate the Amundsen Sea properties along the continuum of Antarctic ice shelf systems, and to understand how these system might change in response to climate change.Pedagogical techniques will be used to provide educational outreach for three distinct target populations: secondary students, pre-service science teachers, and in-service science teachers. Partnerships will be developed with science teacher educators to implement the STEM career-development lessons in undergraduate and graduate level science teachereducation courses.
阿蒙森海位于南大洋遥远的太平洋部分,是研究最少的南极大陆架区域之一。它与其他南极冰架地区有共同的特点,但也表现出独特的方面。阿蒙森海波利尼亚(ASP)是一个开放的区域,位于几个末端冰川的底部,这些冰川正在排出南极西部冰盖的水。1)从变暖的环极深水(mCDW)上升到大陆架上的热量的大入侵,2)南极洲最快融化的冰盖,3)最具生产力的沿海冰间湖(161 g C m-2)以及显著的大气CO2汇,4)地球上季节性离岸海冰下降最快的一些地区。继从早期的海洋学领域的计划,阿蒙森海Polynya国际研究考察(ASPIRE; 2011年),这项研究旨在更好地综合和模拟的物理海洋-冰的联系和生物生产和碳输出条款的相对贡献,并与其他环极南极地区进行比较。一个主要特点是使用一个区域耦合的物理-地球化学模型,跟踪阿蒙森海波利纳每年发生的大型浮游植物水华的动态。这项研究将提供一种方法来定位阿蒙森海属性沿着南极冰架系统的连续性,并了解这些系统可能会如何变化,以应对气候变化。教学技术将被用来提供教育推广的三个不同的目标人群:中学生,职前科学教师,在职科学教师。将与科学教师教育工作者建立伙伴关系,在本科和研究生水平的科学教师教育课程中实施STEM职业发展课程。
