Intellectual meritLong-term preservation of digital data is critical in the sciences and especially so in the ocean sciences where the cost of data acquisition is very high, typically $750K per project for ship time alone, and re-acquiring datasets is generally not feasible. Instrumentation, media and formats are rapidly evolving, more diverse types of sensors are being used, and the volume of data collected is increasing exponentially. While there have been dramatic advances in storage technology, raw storage capacity alone will not solve the long-term data retrieval and preservation problems. Years after data were collected, researchers seeking to re-use the data struggle to discover information about the context of original observations. There is a critical lack of metadatainfrastructure, and substantial barriers often exist between individual projects, diverse computer systems, and different institutions. Because the requirements for long-term preservation of data and those for independent re-use of data have a great deal in common, they can both be met by a common approach, the publication of information in a digital library designed for handling scientific data. This award will establish a multi-institution, scalable digital archiving testbed, combining the efforts of the San Diego Supercomputer Center (SDSC), the Scripps Institution of Oceanography (SIO), and the Woods Hole Oceanographic Institution (WHOI). This inter-institutional demonstration project, will implement a fully functioning digital library, providing a spectrum of curatorial functions including automated ingest, metadata extraction, provenance tracking, validation, quality control, and access control. The combined SIO/WHOI digital library will allow data from approximately 60 new oceanogrphic research projects to be preserved each year, augmenting data from roughly 1600 awards to dozens of institutions over the last 4 decades, over a wide range of disciplines. With the introduction of WHOI data, the testbed will provide access to data, photographs, video images and documents from WHOI ships, Alvin submersible and Jason ROV dives, and deep-towed vehicle surveys. Notions of scalability will be tested, as data volumes range from 3 CDs per cruise to 200 DVDs per cruise. An interactive digital library interface will allow combinations of distributed collections to be browsed, metadatainspected, and objects displayed or selected for download. In addition, web services will be implemented to insure computer-to-computer interoperability, thus helping to streamline data interchange with the NOAA's National Data Centers, and with other major research consortia. Broader impactData and technology from this effort will be incorporated in the second national teachers' workshop for the grantees' ERESE (Enduring Resources for Earth Science Education) Project, scheduled for summer, 2005 at SIO. These efforts will result in direct access for 3000 students in the classrooms of participating teachers, and a wider audience across the Internet as a component of NSF's National Science Digital Library. Seafloor photos and video from Alvin have enthralled schoolchildren around the world for generations. This effort will make these images much more readily accessible to students, teachers and the general public.

在科学中，智力熟悉数字数据的保存至关重要，尤其是在海洋科学中，数据获取成本非常高，通常仅在船舶时间内每项项目$ 750k，而重新获得数据集则通常是不可行的。仪器，媒体和格式正在迅速发展，正在使用更多类型的传感器，并且收集的数据量呈指数增加。尽管存储技术取得了巨大进步，但仅原始存储容量就无法解决长期数据检索和保存问题。收集数据后几年，寻求重新利用数据的研究人员努力发现有关原始观察环境的信息。严重缺乏元素基础设施，单个项目，各种计算机系统和不同机构之间经常存在重大障碍。由于对数据的长期保存和独立重复使用数据的要求有很大的共同点，因此可以通过共同的方法来满足它们，因此在数字图书馆中发布信息，旨在处理科学数据。该奖项将建立一个多机构，可扩展的数字档案测试床，结合了圣地亚哥超级计算机中心（SDSC），Scripps海洋学机构（SIO）和伍兹霍尔海洋学机构（WHOI）的努力。这个机构间的演示项目将实施一个功能齐全的数字图书馆，提供一系列策展功能，包括自动摄入，元数据提取，出处跟踪，验证，验证，质量控制和访问控制。 SIO/WHOI数字图书馆组合将允许每年保存大约60个新的Oceanogrphic研究项目的数据，从而在过去40年中从大约1600个奖励到数十个机构增加数据，并在广泛的学科中增加数据。随着WHOI数据的引入，测试台将提供来自Whoi船，Alvin潜水器和Jason Rov Dives的数据，照片，视频图像和文档的访问权限，并进行了深入的车辆调查。 将测试可扩展性的概念，因为数据量从每次巡航3 CD到每次巡航的200 dvds。交互式数字库界面将允许浏览，元数据和显示或选择的对象的分布式集合的组合。此外，将实施Web服务以确保计算机对计算机的互操作性，从而有助于简化与NOAA国家数据中心以及其他主要研究联盟的数据互换。这项工作中更广泛的影响力和技术将纳入第二个国家教师的ERESE（地球科学教育资源）项目的第二个国家教师研讨会，该项目计划于2005年夏季在SIO举行。这些努力将导致参与教师的教室中有3000名学生以及在互联网上的更多受众群体的直接访问，这是NSF国家科学数字图书馆的组成部分。来自阿尔文（Alvin）的海底照片和视频已经吸引了几代世界各地的学童。这项工作将使这些图像更容易被学生，老师和公众访问。
