This award is for the continuation of the Center for Remote Sensing of Ice Sheets (CReSIS), an NSF Science and Technology Center (STC) established in June 2005 to study present and probable future contributions of the Greenland and Antarctic ice sheets to sea-level rise. The Center?s vision is to understand and predict the role of polar ice sheets in sea level change. In particular, the Center?s mission is to develop technologies, to conduct field investigations, to compile data to understand why many outlet glaciers and ice streams are changing rapidly, and to develop models that explain and predict ice sheet response to climate change. The Center?s mission is also to educate and train a diverse population of graduate and undergraduate students in Center-related disciplines and to encourage K-12 students to pursue careers in science, technology, engineering and mathematics (STEM-fields). The long-term goals are to perform a four-dimensional characterization (space and time) of rapidly changing ice-sheet regions, develop diagnostic and predictive ice-sheet models, and contribute to future assessments of sea level change in a warming climate. In the first five years, significant progress was made in developing, testing and optimizing innovative sensors and platforms and completing a major aircraft campaign, which included sounding the channel under Jakobshavn Isbræ. In the second five years, research will focus on the interpretation of integrated data from a suite of sensors to understand the physical processes causing changes and the subsequent development and validation of models. Information about CReSIS can be found at http://www.cresis.ku.edu.The intellectual merits of the STC are the multidisciplinary research it enables its faculty, staff and students to pursue, as well as the broad education and training opportunities it provides to students at all levels. During the first phase, the Center provided scientists and engineers with a collaborative research environment and the opportunity to interact, enabling the development of high-sensitivity radars integrated with several airborne platforms and innovative seismic instruments. Also, the Center successfully collected data on ice thickness and bed conditions, key variables in the study of ice dynamics and the development of models, for three major fast-flowing glaciers in Greenland. During the second phase, the Center will collect additional data over targeted sites in areas undergoing rapid changes; process, analyze and interpret collected data; and develop advanced process-oriented and ice sheet models to predict future behavior. The Center will continue to provide a rich environment for multidisciplinary education and mentoring for undergraduate students, graduate students, and postdoctoral fellows, as well as for conducting K-12 education and public outreach. The broader impacts of the Center stem from addressing a global environmental problem with critical societal implications, providing a forum for citizens and policymakers to become informed about climate change issues, training the next generation of scientists and engineers to serve the nation, encouraging underrepresented students to pursue careers in STEM-related fields, and transferring new technologies to industry. Students involved in the Center find an intellectually stimulating atmosphere where collaboration between disciplines is the norm and exposure to a wide variety of methodologies and scientific issues enriches their educational experience. The next generation of researchers should reflect the diversity of our society; the Center will therefore continue its work with ECSU to conduct outreach and educational programs that attract minority students to careers in science and technology. The Center has also established a new partnership with ADMI that supports faculty and student exchanges at the national level and provides expanded opportunities for students and faculty to be involved in Center-related research and education activities. These, and other collaborations, will provide broader opportunities to encourage underrepresented students to pursue STEM careers. As lead institution, The University of Kansas (KU) provides overall direction and management, as well as expertise in radar and remote sensing, Uninhabited Aerial Vehicles (UAVs), and modeling and interpretation of data. Five partner institutions and a DOE laboratory play critical roles in the STC. The Pennsylvania State University (PSU) continues to participate in technology development for seismic measurements, field activities, and modeling. The Center of Excellence in Remote Sensing, Education and Research (CERSER) at Elizabeth City State University (ECSU) contributes its expertise to analyzing satellite data and generating high-level data products. ECSU also brings to the Center their extensive experience in mentoring and educating traditionally under-represented students. ADMI, the Association of Computer and Information Science/Engineering Departments at Minority Institutions, expands the program?s reach to underrepresented groups at the national level. Indiana University (IU) provides world-class expertise in CI and high-performance computing to address challenges in data management, processing, distribution and archival, as well as high-performance modeling requirements. The University of Washington (UW) provides expertise in satellite observations of ice sheets and process-oriented interpretation and model development. Los Alamos National Laboratory (LANL) contributes in the area of ice sheet modeling. All partner institutions are actively involved in the analysis and interpretation of observational and numerical data sets.

该奖项是对冰盖遥感中心(CReSIS)的延续，该中心成立于2005年6月，是美国国家科学基金会的一个科学和技术中心(STC)，目的是研究格陵兰和南极冰盖对海平面上升的当前和未来可能的贡献。S中心的愿景是了解和预测极地冰盖在海平面变化中的作用。特别是，S中心的任务是开发技术，进行实地调查，汇编数据，了解为什么许多出口冰川和冰川正在迅速变化，并开发解释和预测冰盖对气候变化响应的模型。S中心的使命也是在中心相关学科教育和培训多样化的研究生和本科生，并鼓励K-12学生在科学、技术、工程和数学(STEM)领域追求职业生涯。长期目标是对快速变化的冰盖区域进行四维表征(空间和时间)，开发诊断和预测冰盖模型，并为未来评估气候变暖中的海平面变化做出贡献。在最初的五年中，在开发、测试和优化创新传感器和平台方面取得了重大进展，并完成了一项主要的飞机活动，其中包括在雅各布港·伊斯布雷的航道上进行探测。在第二个五年中，研究将集中在解释来自一套传感器的综合数据，以了解引起变化的物理过程以及随后的模型开发和验证。有关CRESIS的信息可以在http://www.cresis.ku.edu.The上找到，STC的智力优势在于它使其教职员工和学生能够从事多学科研究，以及它为各级学生提供广泛的教育和培训机会。在第一阶段，该中心为科学家和工程师提供了一个合作研究环境和互动机会，使高灵敏度雷达能够与几个机载平台和创新的地震仪器相结合。此外，该中心还成功地收集了格陵兰三个主要快速流动冰川的冰厚度和河床条件的数据，这些数据是研究冰动力学和开发模型的关键变量。在第二阶段，该中心将在快速变化地区的目标地点收集更多数据；处理、分析和解释收集的数据；并开发先进的面向过程的模型和冰盖模型，以预测未来的行为。中心将继续为本科生、研究生和博士后研究员提供丰富的多学科教育和辅导环境，并为开展K-12教育和公众宣传提供丰富的环境。该中心的更广泛影响来自于解决具有重大社会影响的全球环境问题，为公民和政策制定者提供一个了解气候变化问题的论坛，培训下一代科学家和工程师为国家服务，鼓励未被充分代表的学生从事与STEM相关的职业，以及将新技术转移到工业中。参与该中心的学生找到了一种激发智力的氛围，在这种氛围中，学科之间的合作是常态，接触各种方法和科学问题可以丰富他们的教育经验。下一代研究人员应该反映我们社会的多样性；因此，该中心将继续与ECSU合作，开展外联和教育方案，吸引少数族裔学生投身科学和技术职业。该中心还与ADMI建立了新的合作伙伴关系，支持国家层面的教职员工交流，并为学生和教职员工提供更多参与中心相关研究和教育活动的机会。这些合作，以及其他合作，将提供更广泛的机会，鼓励代表不足的学生追求STEM职业。作为牵头机构，堪萨斯大学(KU)提供全面的指导和管理，以及雷达和遥感、无人驾驶飞行器(UAV)以及数据建模和解释方面的专业知识。五个伙伴机构和一个能源部实验室在STC中发挥关键作用。宾夕法尼亚州立大学(PSU)继续参与地震测量、野外活动和建模的技术开发。伊丽莎白城州立大学遥感、教育和研究英才中心(CERSER)为分析卫星数据和生成高水平数据产品贡献了其专门知识。ECSU还将他们在指导和教育传统上代表不足的学生方面的丰富经验带给该中心。ADMI，少数民族院校计算机和信息科学/工程系协会，将S项目扩大到全国范围内代表性不足的群体。印第安纳大学(IU)在CI和高性能计算方面提供世界一流的专业知识，以应对数据管理、处理、分发和归档方面的挑战，以及高性能建模要求。华盛顿大学(UW)在卫星观测冰盖以及面向过程的解释和模型开发方面提供专门知识。洛斯阿拉莫斯国家实验室(LANL)在冰盖模拟领域做出了贡献。所有伙伴机构都积极参与对观测和数字数据集的分析和解释。
