This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The Amundsen Sea Polynya is areally the most productive Antarctic polynya, exhibits higher chlorophyll levels during peak bloom and greater interannual variability than the better-studied Ross Sea Polynya ecosystem. Polynyas may be the key to understanding the future of polar regions as their extent is expected to increase with anthropogenic warming. The project will examine 1) sources of iron to the Amundsen Sea Polynya as a function of climate forcing, 2) phytoplankton community structure in relation to iron supply and mixed-layer depths, 3) the efficiency of the biological pump of carbon to depth and 4) the net flux of carbon as a function of climate and micronutrient forcing. The research also will compare results for the Amundsen Sea to existing data synthesis and modeling efforts for the Palmer LTER and Ross Sea. The project will 1) build close scientific collaborations between US and Swedish researchers; 2) investigate climate change implications with broad societal relevance; 3) train new researchers; 4) encourage participation in research science by underrepresented groups, and 5) involve broad dissemination of results via scientific literature and public outreach, including close interactions with NSF-supported PolarTrec and COSEE K-12 teachers

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。阿蒙森海Polynya实际上是南极最多产的Polynya，在高峰开花期间叶绿素水平较高，年际变化比研究得更好的罗斯海Polynya生态系统更大。冰湖可能是了解极地未来的关键，因为它们的范围预计会随着人为变暖而增加。该项目将研究1)阿蒙森海多冰区铁的来源作为气候强迫的函数，2)浮游植物群落结构与铁供应和混合层深度的关系，3)碳向深度的生物泵的效率，以及4)碳的净通量作为气候和微量营养素强迫的函数。该研究还将比较阿蒙森海的结果与帕尔默LTER和罗斯海的现有数据综合和建模工作。该项目将1)在美国和瑞典研究人员之间建立密切的科学合作；2)研究具有广泛社会意义的气候变化影响；3)培养新的研究人员；4)鼓励代表性不足的群体参与科学研究，5)通过科学文献和公众宣传广泛传播研究结果，包括与nsf支持的PolarTrec和COSEE K-12教师的密切互动
