Intellectual Merit: This award supports the development of an Arctic Oceanographic Data Discovery and Visualization System that complements those already available for the Atlantic, Pacific, Indian and Southern oceans. The effort focuses on geological and geophysical information of the Arctic Ocean and its neighboring seas extending south to 60°N. A significant component of the effort will be the processing, for the first time, of a large volume of multibeam echo-soundings acquired by the USCGC 'Healy' into digital elevation models and multiple-resolution tile sets. These data will be supplemented by water column data, sub-bottom reflection profiles, deep-sea sediment drilling results and seabed sediment sampling, as well as geophysical measurements of magnetic and gravity fields. Broader Impacts: Undergraduate students will be integral to the multibeam data processing. The data and information will be efficiently and effectively displayed and delivered via Web services for the benefit of researchers, educators, students and the general public. The established, non-proprietary Web applications, 'GeoMapApp' and 'Virtual Ocean', that are the backbone of the effort do not require expert skills, and, as a result, are appropriate tools for teaching and outreach. The project will develop 'mini-lessons' and outreach materials that exemplify the educational possibilities of 'GeoMapApp' and 'Virtual Ocean'.

智力优势：该奖项支持北极海洋学数据发现和可视化系统的开发，以补充大西洋，太平洋，印度洋和南大洋的现有系统。这项工作的重点是北冰洋及其向南延伸到60°N的邻近海域的地质和地球物理信息。这项工作的一个重要组成部分将是首次将USCGC“希利”号获得的大量多波束回声测深数据处理成数字高程模型和多分辨率瓦片集。这些数据将得到水柱数据、海底反射剖面、深海沉积物钻探结果和海底沉积物采样以及磁场和重力场地球物理测量的补充。更广泛的影响：本科生将成为多波束数据处理的一部分。数据和信息将通过万维网服务高效率和有效地显示和提供，以造福于研究人员、教育工作者、学生和公众。已建立的非专有网络应用程序"GeoMapApp“和”虚拟海洋“是这项工作的支柱，不需要专业技能，因此是教学和外联的适当工具。该项目将开发“微型课程”和宣传材料，以宣传“GeoMapApp”和“虚拟海洋”的教育可能性。
