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.

WAIS（西南极冰盖）会议自 1994 年以来每年举行一次。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，引起了政策制定者和公众的担忧。 对下个世纪海平面上升的预测表明，大型极地冰盖（特别是格陵兰冰盖、南极半岛和南极洲西部阿蒙森海区的边际融化）是主要贡献者，但这些贡献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的约束，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。在过去的二十年中，极地冰盖在全球环境和社会问题中的作用变得越来越重要。 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。 该研讨会奖项支持召开一次会议，该会议将研究这些问题并制定未来的社区战略。要解决的特定科学主题是：1）海洋与冰的相互作用：有多重要以及如何理解？ 2）基本属性：毫米到公里尺度的重要性；热流； 3）冰盖模型：最新进展和未来展望； 4) 观测：卫星、飞机、滑雪板和冰爪； 5）冰盖的历史：冰芯、海底特征、地质学。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，该奖项为参与者支持提供资金，这将降低许多参与者的出席成本。该奖项更广泛的影响是，将优先支持那些过去缺席的早期职业科学家、代表性不足群体的科学家、学生以及对 WAIS 重要的科学学科的科学家。会议将于 2010 年 9 月下旬在宾夕法尼亚州中部举行。WAIS 是一次强跨学科、高知名度的会议。学生和研究人员在非正式的环境中交流，鼓励自由交流思想。 WAIS 会议汇集了来自多个领域的科学家，重点关注了解冰盖和海平面的相互作用，而这两个领域目前还存在很大的不确定性。
