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.

南大洋偏远太平洋地区的阿蒙森海是研究最少的南极大陆架地区之一。它与其他南极冰架区域具有共同的特征，但也表现出独特的方面。 Amundsen Sea Polynya（ASP）是几个末端冰川底部的一个开放区域，排干南极冰盖的冰层表现出：1）大量的热量从变暖的圆形深水（MCDW）上升到大陆架子上的圆形冰层（MCDW）上升到大陆架上的大陆架子，2）在盖尔克（Antortal Belf）上，2）最重要的杂物（16），均为16层（3），3层（3），3层（3），3层（3），3层（3）大气中的二氧化碳水槽和4）地球上季节性海冰季节性海冰地区一些最快下降的地区。在较早的海洋现场计划之后，Amundsen Sea Polynya国际研究探险（Aspire; 2011）试图更好地综合和模拟物理海洋冰链接，生物生产和碳出口术语的相对贡献，并将其与其他极度圆形反激区域进行比较。中心特征将是使用区域耦合的物理生物地球化学模型遵循每年在Amundsen Sea Polyna中每年发生的大型浮游植物开花的动力学。这项研究将提供一种方法，以定位南极冰架系统连续体的Amundsen Sea Properties，并了解这些系统可能会随着气候变化的响应而发生变化。PepogogicalTechniques将用于为三个不同的目标人群提供教育外展：中学生，服务前科学教师和服务科学教师。将与科学教师教育者建立合作伙伴关系，以在本科和研究生级别的科学教师教育课程中实施STEM职业发展课程。
