An Archive and Data Distribution System for Glaciological and Cryospheric System Data from the U.S. Antarctic Program: The Antarctic Glaciological Data Center (AGDC)

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的和过去的现场数据创建一个永久记录，并将确保在前几年的项目结束或私家侦探退休时获得较旧的数据。南极冰川学数据中心(AGDC)将仿照NSIDC目前的北极系统科学(ARCS)数据管理计划，该计划在过去八年中取得了证明的成功，并将是NSIDC作为美国南极数据协调中心(ADCC)角色的合理延伸，ADCC提供关于USAP研究活动频谱的数据集信息。数据中心的存在消除了从私人投资者那里归档和分发数据的负担--这是他们在目前由ADCC资助的情况下保留的负担。数据协议将与西南极冰盖(WAIS)计划和国际跨南极科学考察(US ITASE)的美国部分等USAP关键倡议协调制定，以确保最终广泛获取其数据，同时包括一段适当的时间段，在此期间私人投资者将独家使用数据。收集和存档的数据类型包括来自冰芯和雪坑的物理和地球化学数据、冰面海拔高度、内层记录、来自雷达剖面的冰厚度和基岩地形、积雪、颗粒大小、能见度、地表和10米积雪温度、来自遥感图像的冰速测量数据、实地勘测数据和特点良好的数字地震和雷达剖面数据。拟议工作的基本目的是提供一种简单、协调和适当的手段，促进最广泛地利用USAP收集的冰川学和相关数据。

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.
