This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This project involves a resampling of several small ponds in the tundra near Barrow, Alaska that were studied intensively in the early 1970s as part of the International Biological Project (IBP) ? Tundra Biome Project. The principal objective of this proposal is to re-sample historic sites and, together with additional sampling methodologies, determine if the physical, chemical and biological environment of tundra ponds on Alaska?s coastal plain have changed in response to recent warming and/or anthropogenic alteration. Key activities will include: 1. Re-sampling IBP tundra ponds for physical, chemical and biological variables last surveyed nearly 40 years ago. 2. Comparing IBP tundra ponds, now being affected by a warming climate and encroaching development, to similar habitats in the region to determine whether they represent the best regional sites to monitor in the long-term, or if they have been overly impacted by development. 3. Investigating possible drivers of change for tundra pond ecosystems under several possible warming scenarios. 4. Establishing new protocols for continuous measurement of parameters of interest. 5. Educating the next generation of polar scientists about Arctic aquatic ecology, data rescue and scientific reporting.This project will support a graduate student and several undergraduates, and include outreach to the Barrow community and schools.

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。该项目涉及在阿拉斯加巴罗附近的苔原上重新种植几个小池塘，这些池塘在20世纪70年代初作为国际生物项目（IBP）的一部分进行了深入研究。苔原生物群落项目。这项建议的主要目标是重新对历史遗址进行取样，并结合其他取样方法，确定阿拉斯加苔原池塘的物理、化学和生物环境是否存在差异。的沿海平原已经改变了响应最近的变暖和/或人为改变。主要活动包括：1.对IBP苔原池塘进行重新取样，以确定近40年前最后一次调查的物理、化学和生物变量。2.比较IBP苔原池塘，现在受到气候变暖和侵蚀发展的影响，在该地区的类似栖息地，以确定它们是否代表最好的区域网站，以监测在长期内，或者如果他们已经过度发展的影响。3.在几种可能的变暖情景下调查冻原池塘生态系统变化的可能驱动因素。4.建立连续测量感兴趣参数的新协议。5.教育下一代极地科学家了解北极水生生态、数据抢救和科学报告。该项目将支持一名研究生和几名本科生，并包括与巴罗社区和学校的外联。
