Science-Driven Cyberinfrastructure: Integrating Permafrost Data, Services, and Research Applications

科学驱动的网络基础设施：整合永久冻土数据、服务和研究应用该项目建议使用网络基础设施工具，为科学界提供服务，以便访问和发现选定的永久冻土数据集。多年冻土被全球气候监测机构视为环境指标和基本气候变量--S。为了更好地了解其当前和过去的状态，有必要改进对永久冻土数据集(目前分散在网络上的许多地方)的访问。全球科学界和政策界需要全面、最新的永久冻土分布和状况地图。通过使多年冻土数据更易于使用，该项目支持目前由每个实验室使用永久冻土数据重复的数据集成工作，并将通过腾出关键时间进行独特研究来促进知识的发展。项目成果对政策制定者、更广泛的科学研究人员、土著社区、基于社区的监测项目以及居住在永久冻土上或靠近永久冻土并对其进行研究的其他人直接有用。通过科学驱动的网络基础设施，研究团队将产生一套可扩展的、多方面的服务，以解决永久冻土数据获取和可用性的复杂性。认识到在这一领域协调努力的重要性，该项目将从以前的努力停止的地方开始。这项研究利用了国际多年冻土协会和全球陆地冻土网络(GTN-P)网络基础设施方面的进展，促进了多年冻土社区的利益，并为这一必要的系统提供了宝贵的功能和数据。具体的项目目标是：1)以经济高效的方式聚合、提取、预处理、标准化和重组GTN-P网络以外的数据，通过整合国家冰雪数据中心(NSIDC)、冻土数据中心(FGDC)和高级北极合作数据和信息服务(ACADIS)网关持有的宝贵数据，增加GTN-P系统的广度和深度。2)通过扩展GTN-P本体来扩展语义基础设施，以包括更广泛的冻土和气候建模概念以及用于数据发现、集成和重用的术语。3)将GTN-P元数据和系统集成到北极数据探索器分布式搜索门户网站和北极观测查看器数据采集地图中，以支持联合数据访问。4)通过开发可视化服务来提高数据可用性，这些服务可以快速生成多个空间比例的定制地图，以向研究人员、公民科学家和政策制定者提供信息。

Science-Driven Cyberinfrastructure: Integrating permafrost data, services, and research applicationsThis project proposes the use of cyberinfrastructure tools for providing services to the scientific community for accessing and discovering selected permafrost datasets. Permafrost is deemed as an Environmental Indicator and an Essential Climate Variable by agencies monitoring the Earth?s climate. Improved access to permafrost datasets (currently scattered over many places on the web) is necessary for better understanding its current and past state. Global scientific and policy communities need comprehensive, up-to-date maps of permafrost distribution and status. By making permafrost data easier to use, this project supports data integration work currently duplicated by every lab using permafrost data and will advance knowledge by freeing critical time for unique research. Project outcomes are directly useful to policy-makers, broader science researchers, indigenous communities, community-based monitoring programs, and others living on or in close proximity to and studying permafrost. Through science-driven cyberinfrastructure, the research team will produce a set of scalable, multi-faceted services to address the complexity of permafrost data access and usability. Recognizing the importance of coordinated efforts in this area, the project will start where previous efforts left off. This research leverages progress in International Permafrost Association and Global Terrestrial Network - Permafrost (GTN-P) cyberinfrastructure, advances permafrost community interests, and contributes valuable functionality and data to this necessary system. Specific project objectives are: 1) Aggregate, extract, pre-process, standardize, and reorganize data from beyond the GTN-P network in a cost-effective manner, increasing the breadth and depth of the GTN-P system by integrating valuable data holdings from the National Snow and Ice Data Center (NSIDC) Frozen Ground Data Center (FGDC) and Advanced Cooperative Arctic Data and Information Service (ACADIS) Gateway. 2) Extend semantic infrastructure by expanding the GTN-P ontology to include broader permafrost and climate modeling concepts and terms for data discovery, integration, and reuse. 3) Integrate GTN-P metadata and systems into the Arctic Data Explorer distributed search portal, and Arctic Observing Viewer data collection map to support federated data access. 4) Improve data usability by developing visualization services that quickly produce customized maps at multiple spatial scales to deliver information to researchers, citizen scientists, and policy makers.
