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，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年度会议。该奖项的学术价值在于，目前对下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。对下个世纪海平面上升的预估表明，大型极地冰盖（特别是格陵兰冰盖和南极半岛以及西南极洲阿蒙森海部分的边缘融化）是主要因素，但这些因素的幅度和时间存在很大的不确定性。要获得对这些不确定性的更好约束，需要更好的冰盖模型和更好的冰盖模型输入，以及包括冰盖建模者、海洋建模者和观测工作在内的协调一致的跨学科努力。在过去二十年中，极地冰盖在全球环境和社会问题方面的作用越来越重要。WAIS团体由冰川学家、地质学家、大气和地球科学家、海洋学家等组成。这个工作坊奖将支持一个会议，该会议将审查这些问题，并将为未来制定社区战略。要讨论的特定科学主题是：1)海洋与冰的相互作用：有多重要？2)基础性质：mm - km尺度重要性；热流;3)冰盖模型：最新进展与未来展望；4)观测：卫星、飞机、雪橇、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，该奖项为参与者提供资金支持，这将降低许多参与者的出席成本。该奖项更广泛的影响是，将优先支持早期职业科学家、来自代表性不足群体的科学家、学生和来自对WAIS重要的科学学科的科学家，这些科学家过去一直缺席。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鼓励自由交流思想的非正式环境中交流。WAIS会议将来自许多领域的科学家聚集在一起，他们的中心重点是了解冰盖和海平面的相互作用，这些相互作用还存在很大的不确定性。
