Shaver 0632139Bret-Harte 0632264Funds are provided to establish two observatories, in the U.S. and Russia, and form a PanArctic network of observatories where coordinated measures of landscape-level carbon, water, and energy balance are carried out and results made available in a unified database. The observatories will be establishedat two existing sites of research on landscape-level carbon, water, and energy balance - Toolik Lake (Alaska) and Cherskii (Siberia) - and the network of observatories across the Arctic where similar long-term observations of carbon, water and energy variables are made or proposed as part of IPY will include Toolik, Cherskii, Abisko (Sweden, the main site of the ABACUS project), Zackenberg (Greenland), and several sites in Arctic Canada.Funds are specifically provided for instruments and personnel at Toolik and Cherskii, as well as international workshops and visits among the sites to ensure that data and instrumentation are easily comparable. Rather than studying one process at a time, this effort focuses on simultaneous measurements of carbon, water, and energy fluxes of the Arctic terrestrial landscape at hourly, daily, seasonal, and multiyear time scales. These are majorregulatory drivers of the Arctic System, forming key linkages and feedbacks between the land surface, the atmosphere, and the oceans. The data collected will become a legacy by using measurement and data archiving approaches that are comparable among observatories. The data management protocols and archives used for nearly 20 years by the NSF Arctic Long Term Ecological Research (LTER) project (based at Toolik Lake) will be used; data will be archived in the Arctic LTER database and, through links to the National Snow and Ice Data Center (NSIDC), will be generally available to the community.

Shaver 0632139 Bret-Harte 0632264Funds用于在美国和俄罗斯建立两个观测站，并形成全北极观测站网络，在该网络中对地貌层面的碳、水和能源平衡进行协调测量，并在统一的数据库中提供结果。将在图利克湖(阿拉斯加)和切尔斯基湖(西伯利亚)这两个现有的地貌碳、水和能量平衡研究站点建立观测站，并在北极各地建立观测站网络，在那里作为国际地球年的一部分，对碳、水和能源变量进行或提议进行类似的长期观测，这些观测站网络将包括图利克、切尔斯基、阿比斯科(瑞典，算盘项目的主要站点)、扎肯贝格(格陵兰)和加拿大北极的几个站点。专门为图利克湖和切尔斯基湖的仪器和人员以及国际讲习班和站点之间的访问提供资金，以确保数据和仪器设备易于比较。这项工作不是一次研究一个过程，而是专注于在每小时、每天、季节和多年的时间尺度上同时测量北极陆地景观的碳、水和能量通量。这些都是北极系统的主要调节动力，形成了陆地表面、大气和海洋之间的关键联系和反馈。收集的数据将通过使用可在各观测站之间进行比较的测量和数据存档方法而成为遗产。将使用美国国家科学基金会北极长期生态研究项目(设在图利克湖)近20年来使用的数据管理协议和档案；数据将存档在北极长期生态研究数据库中，并通过与国家冰雪数据中心的链接向社区普遍提供。
