The Antarctic Glaciological Data Center: Continued Data Collection and Management for Antarctic Glaciology

该合同为国家冰雪数据中心（NSIDC）的南极冰川学数据中心（AGDC）提供了持续的支持，该中心是美国南极计划（USAP）的冰川学数据的存档和数据分发系统。这项正在进行的努力已经建立了一个网站，其中包括最近从许多主要研究人员那里收集的南极冰川学和相关数据，并汇编了重要的冰川学参数的产品，如冰流速度和10米温度。AGDC有两个指导目标：积累由美国国家科学基金会资助的南极冰川学资助的研究数据记录；并为南极冰川学项目的主要研究人员提供对野外规划、建模或研究分析有用的基本地球物理参数。AGDC与美国南极数据协调中心有关，但不是该中心的一部分，后者是有关所有南极研究的元数据信息的存储库。在第二个五年期间，AGDC将以若干方式改进总体活动。来自US-ITASE项目的大量P.I.数据集将随着这些数据的发布和存档而增加。来自当前冰川学研究的其他数据集也将被加入。AGDC将为处理选定的动力学和热力学建模结果以及破冰雷达数据集制定适当的方案。到目前为止，这两种数据类型已被证明难以管理。AGDC还将继续建立当前的“汇编产品”数据集，并在其中添加积雪测量和深冰温度剖面的汇编。将咨询一个新成立的主要研究人员审查小组，以提供指导和附加的数据建议。该项目的智力价值在于，数据中心通过向研究人员提供从过去和最近的活动中获得的详细描述的数据，从而支持基本的冰川学研究。通过让这些数据可以在网上访问，如果需要人工协助，调查人员可以更快地探索想法，更容易地找到所需的信息和引用。数据中心的更广泛的影响是，它还为感兴趣的公众提供了获取南极洲信息和图片的途径，并将这些高水平的信息链接到NSIDC网络上更面向外联的站点。此外，作为信息和数据的长期档案，AGDC站点是南极洲科学探索的记录，随着时间的推移，它将变得越来越有价值。

Scambos0338134This award provides continued support for the Antarctic Glaciological Data Center (AGDC) at The National Snow and Ice Data Center (NSIDC), an archive and data distribution system for glaciological data from the U.S. Antarctic Program (USAP). This on-going effort has created a website containing recently gathered Antarctic glaciological and related data from numerous principal investigators, and compiled products of important glaciological parameters such as ice flow velocity and 10-meter temperature. The AGDC has two guiding objectives: to accumulate a record of research data from NSF-funded Antarctic glaciology grants; and to provide principal investigators in the Antarctic Glaciology program with basic geophysical parameters useful for field planning, modeling, or research analysis. The AGDC is related to, but not a part of, the U.S. Antarctic Data Coordination Center, a repository of metadata information about all Antarctic research.In this second five-year period the AGDC will improve the overall activity in a number of ways. A large number of P.I. data sets from the US-ITASE project will be added as those data are published and becoming available for archival. Additional data sets from current glaciological research will be added as well. AGDC will develop appropriate schemes for handling selected dynamic and thermodynamic modeling results, and ice-penetrating radar data sets. These are two data types that have proven difficult to manage up to now. AGDC will also continue to build the current "Compiled Product" data sets, and add to them a compilation of snow accumulation measurements, and deep ice temperature profiles. A newly-formed review panel of principal investigators will be consulted for guidance and additional suggestions of data to incorporate. The intellectual merit of the project is that the data center supports basic glaciological research by providing researchers with ready access to well-described data from past and recent activities. By having these data web-accessible, with human assistance if needed, investigators can explore ideas more rapidly, and find needed information and citations more easily. The broader impacts of the data center are that it also provides the interested public with access to information and pictures of Antarctica, and links this somewhat high-level information to more outreach-oriented sites on the NSIDC web. Further, as a long-term archive of information and data, the AGDC site is a record of the scientific exploration of Antarctica, which will become increasingly valuable with the passage of time.
