中文摘要
该项目将继续美俄合作,编纂泛北极排水系统的数据。俄罗斯主要河流系统的数据将被提供,数字化,并用于水平衡模型。该项目将通过将河流流量、气候和组成数据库更新到2000年来扩大目前的估计。建模工作将扩展时间范围,以模拟6000至20000年前选定时期的河流径流、河流路线和排放制度。改善的水和成分平衡将有助于了解欧亚的水文和物质循环,了解欧亚陆地和大陆架之间的耦合,以及了解北极和全球环流。该项目将为了解北极水文对全球淡水平衡的作用提供基础。平衡的变化至关重要,因为水量巨大(世界上10%的淡水径流流向北冰洋),而且它在对全球变暖敏感的海冰形成中起着重要作用。
英文摘要
This project will continue a U.S.-Russian collaboration to compile data on the pan-Arctic drainage system. Russian data for the major river systems will be made available, digitized, and used in a water balance model. The project will extend current estimates by updating the river discharge, climate, and constituent databases to the year 2000. The modeling effort will extend the time horizon to simulate river runoff, river routing, and discharge regimes at selected periods from 6000 to 20,000 years ago. The improved water and constitution balances will provide understanding of Eurasian hydrologic and material cycles, for understanding the coupling between the Eurasian land and shelf, and for understanding Arctic and global circulation. This project will provide the basis for understanding the role of the Arctic hydrologic on global freshwater balance. Changes in the balance are critically important because of the large volume (10% of the world's freshwater runoff goes to the Arctic Ocean) and its role on sea ice formation which is sensitive to global warming.
