Abstract This MRI award to researchers and engineers from WHOI and University of Michigan seek to assemble a suite of instrumentation to further both research and educational training into the practical and theoretical aspects of the navigation and communication capabilities of Autonomous Underwater Vehicles (AUVs). The application focus is to encourage a more routine operation of relatively inexpensive AUVs in under sea-ice, floating ice shelves and large iceberg environments. Such studies are recognized (e.g. IPCC AR4) as critical needs to our understanding of climate induced changes in the cryosphere, and the implications such changes may have for future sea level rise, planetary albedo, and other aspects of climate prediction. Our current limited understanding of ice/ocean interactions at the terminal margins of Greenland and Antarctic ice sheets are notably lacking in direct and sustained observation of factors such as basal roughness, subglacial hydrology and topographic conditions, temporal and spatial variability of ice sheet and meltwater flow fields, ocean thermal, salinity and current fields. Awareness of the approach and progress to its realization will be communicated by the investigators to the public and K-12 activities under ongoing programs at their respective institutions. Successful results will be of immediate interest to polar and climate scientists engaged in observation and modeling studies. The increasing number of small AUVs that exist in the US academic and oceanographic agencies provides a natural focus for student involvement in research and development projects.

世界卫生组织和密歇根大学向研究人员和工程师颁发的这一MRI奖旨在组装一套仪器，以进一步研究和教育自主水下航行器(AUV)导航和通信能力的实践和理论方面的培训。应用重点是鼓励相对便宜的AUV在海冰下、浮动冰架和大型冰山环境中进行更常规的操作。这类研究(如IPCC AR4)被认为是我们理解气候引起的冰冻圈变化的关键需要，以及这种变化可能对未来海平面上升、行星反照率和气候预测的其他方面产生的影响。我们目前对格陵兰和南极冰盖末端边缘的冰/海洋相互作用的了解有限，明显缺乏对基准面粗糙度、冰川下水文和地形条件、冰盖和融水流场的时空变异性、海洋热力、盐度和洋流等因素的直接和持续观察。调查人员将根据各自机构正在进行的方案，向公众和K-12活动通报对这一方法及其实现进展的认识。成功的结果将直接关系到从事观测和建模研究的极地和气候科学家的利益。美国学术和海洋机构中越来越多的小型AUV为学生参与研究和开发项目提供了自然的焦点。
