The WAIS (West Antarctic Ice Sheet) meetings have been held annually since 1994. This award supports the 17th annual WAIS meeting at the Pennsylvania State University. The intellectual merit of this award is that there are currently large uncertainties in sea-level rise estimates over the next century that are cause for concern for policymakers and the public. Projections of sea-level rise for the next century implicate the large polar ice sheets (in particular, marginal melt of the Greenland Ice Sheet and of the Antarctic Peninsula and the Amundsen Sea sector of West Antarctica) as the major contributors, but with significant uncertainty on the magnitude and timing of those contributions. Obtaining better constraints on those uncertainties requires better ice-sheet models and better inputs to the ice-sheet models, and a concerted, interdisciplinary effort including ice sheet modelers, ocean modelers, and observational efforts. Over the last two decades, the role of the Polar ice sheets has grown in importance with regards to global environmental and societal concerns. The WAIS community consists of glaciologists, geologists, atmospheric- and earth-scientists, oceanographers, and others. This workshop award supports a meeting that will examine these questions and will formulate a community strategy for the future. The particular science topics to be addressed are: 1) Ocean & Ice interactions: how important and how well-understood?; 2) Basal properties: mm to km scale importance; heat flow; 3) Ice sheet models: recent advances and future prospects; 4) Observations: satellites, airplanes, skidoos, and crampons; 5) History of the ice sheet: ice cores, ocean-bottom features, geology. In order to encourage a broad representation of early career scientists and scientists who might not have attended WAIS previously, this award provides funding for participant support that will lower the cost of attendance for many of the attendees. The broader impacts of this award are that priority for support will be given to early-career scientists, scientists from underrepresented groups, students, and scientists from science disciplines of importance to WAIS who have been absent in the past.The meeting will be held in central Pennsylvania in late September, 2010. WAIS is strongly interdisciplinary and high-visibility meeting. Students and researchers mingle in an informal setting that encourages the free exchange of ideas. WAIS meetings bring together scientists from many fields with a central focus on understanding ice sheets and sea level interactions, which as yet have large uncertainties.

自1994年以来，WAIS（西南极冰盖）会议每年举行一次。该奖项支持在宾夕法尼亚州立大学举行的第17届WAIS年会。该奖项的学术价值在于，目前对下一个世纪海平面上升的估计存在很大的不确定性，这引起了决策者和公众的关注。 对下一个世纪海平面上升的预测表明，极地大冰盖（特别是格陵兰冰盖和南极半岛以及南极洲西部阿蒙森海部分的边缘融化）是主要的促成因素，但这些促成因素的程度和时间却很不确定。为了更好地限制这些不确定性，需要更好的冰盖模型和更好的冰盖模型输入，以及协调一致的跨学科努力，包括冰盖建模，海洋建模和观测工作。在过去的二十年里，极地冰盖的作用在全球环境和社会问题方面变得越来越重要。WAIS社区由冰川学家，地质学家，大气和地球科学家，海洋学家等组成。 这个研讨会奖支持一个会议，将审查这些问题，并将制定一个社区的未来战略。要解决的具体科学问题是：1）海洋冰的相互作用：有多重要和如何理解？ 2)基本性质：毫米到公里尺度的重要性;热流; 3）冰盖模型：最近的进展和未来的前景; 4）观测：卫星，飞机，滑雪，冰爪; 5）冰盖的历史：冰芯，海底特征，地质。为了鼓励早期职业科学家和以前可能没有参加过WAIS的科学家的广泛代表性，该奖项为参与者提供资助，这将降低许多与会者的出席成本。该奖项的更广泛的影响是，优先支持将给予早期的职业科学家，科学家从代表性不足的群体，学生，科学家的重要性，WAIS谁是在过去缺席的科学学科。会议将于2010年9月下旬在宾夕法尼亚州中部举行。 WAIS是一个跨学科和高知名度的会议。学生和研究人员在一个非正式的环境中混合，鼓励自由交流思想。 WAIS会议汇集了来自许多领域的科学家，重点是了解冰盖和海平面的相互作用，这还具有很大的不确定性。
