项目摘要

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

该奖项根据 2009 年《美国复苏和再投资法案》（公法 111-5）提供资金。阿蒙森海冰间湖是南极洲生产力最高的冰间湖，与经过深入研究的罗斯海冰间湖生态系统相比，在盛花期叶绿素水平更高，年际变化也更大。冰间湖可能是了解极地地区未来的关键，因为其范围预计会随着人为变暖而扩大。该项目将研究 1) 阿蒙森海冰间湖的铁来源与气候强迫的函数关系，2) 与铁供应和混合层深度相关的浮游植物群落结构，3) 生物泵将碳输送至深度和深度的效率。 4) 净碳通量作为气候和微量营养素强迫的函数。该研究还将阿蒙森海的结果与帕尔默 LTER 和罗斯海的现有数据合成和建模工作进行比较。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) 调查具有广泛社会意义的气候变化影响； 3）培训新的研究人员； 4) 鼓励代表性不足的群体参与科学研究，以及 5) 通过科学文献和公共宣传广泛传播成果，包括与 NSF 支持的 PolarTrec 和 COSEE K-12 教师密切互动
