This award supports the establishment of an archive and data distribution system for glaciological and cryospheric data from the U.S. Antarctic Program (USAP). The archive would create a permanent record for upcoming and past field data and would ensure the availability of older data as programs from previous years come to an end or as P.I.s retire. The Antarctic Glaciological Data Center (AGDC) would be modeled on the current Arctic System Science (ARCSS) data management program at NSIDC, which has been a demonstrated success over the last eight years, and would be a logical extension of NSIDC's role as the U.S. Antarctic Data Coordination Center (ADCC), which provides data set information on the spectrum of USAP research activities. The presence of a data center removes the burden of archiving and distributing data from P.I.s- a burden they retain under the currently-funded ADCC. A data protocol would be developed in concert with key USAP inititatives like the West Antarctic Ice Sheet (WAIS) program and the U.S. component of the International Trans-Antarctic Scientific Expedition (US ITASE) to ensure eventual broad access to their data, while including an appropriate period during which P.I.s would have exclusive use of the data. Examples of the types of data that would be collected and archived include physical and geochemical data from ice cores and snow pits, ice surface elevations, internal layer records, ice thickness and bedrock topography from radar profiles, snow accumulation, grain-size, ablbedo, surface and 10-meter snow temperatures, ice velocity measurements from remote sensing imagery, field survey data and well-characterized digital seismic and radar profile data. The fundamental purpose of the proposed effort is to provide a simple, coordinated, and appropriate means of facilitating the broadest possible utilization of glaciological and related data collected by the USAP.

该奖项支持建立美国南极计划（USAP）冰川学和冰冻圈数据的档案和数据分发系统。 该档案将为即将到来和过去的现场数据创建永久记录，并将确保旧数据的可用性，因为前几年的计划即将结束或P.I.退休。 南极冰川学数据中心（AGDC）将以NSIDC目前的北极系统科学（ARCSS）数据管理计划为模型，该计划在过去八年中取得了成功，并将成为NSIDC作为美国南极数据协调中心（ADCC）的角色的合理延伸，该中心提供有关USAP研究活动范围的数据集信息。 数据中心的存在消除了P.I.的归档和分发数据的负担-这是他们在目前资助的ADCC下保留的负担。 数据协议将与USAP的关键倡议（如西南极冰盖（WAIS）计划和国际跨南极科学考察（US ITASE）的美国部分）一起制定，以确保最终广泛获得他们的数据，同时包括一个适当的时期，在此期间，PI将独家使用数据。 将收集和存档的数据类型的例子包括：从冰芯和雪坑获得的物理和地球化学数据、冰面高程、内层记录、从雷达剖面图获得的冰厚和基岩地形、积雪、粒度、消融、表面和10米雪温、从遥感图像获得的冰速测量值、现场勘测数据和特征明确的数字地震和雷达剖面数据。 建议的努力的基本目的是提供一个简单的，协调的，适当的手段，促进尽可能广泛地利用冰川和相关数据收集的USAP。
