Soviet Rivers: Analytical Component

1990年夏天，在一次非常成功的探险中，从苏联领土流入黑海的河流被取样。建议通过将这项工作扩展到东部的河流，继续和发展与苏联科学家的合作。我们的苏联同事提议在1991年春季对咸海的两个富水区阿姆达里亚和锡尔达里亚的源头进行采样，在1991年夏天开始上莱纳河的工作，并在1992年研究下莱纳河和印地吉尔卡河。这些研究将提供有关苏联河流风化产生量的宝贵信息，从而大大加强全球物质平衡研究的数据库。东部的河流排干了独特的未冰川的亚北极环境。这将允许对风化过程与南美洲著名的热带河流进行比较研究，这些河流排放类似的岩石类型。该项目还将提供最有可能首先受到温室气体变暖影响的地区的基线信息。

The rivers flowing into the Black Sea from the territory of the Soviet Union were sampled on a very successful expedition in the Summer of 1990. It is proposed to continue and develop this collaboration with Soviet scientists by extending this work to the rivers of the East. Our Soviet colleagues have proposed that the headwaters of the two affluents of the Aral Sea, Amu Darya and Syr Darya, be sampled in the Spring of 1991, that work on the Upper Lena begin in the Summer of 1991 and that the Lower Lena and Indigirka be studied in 1992. These studies will provide valuable information on the weathering yield from the rivers of the Soviet Union thereby greatly strengthening the data base for global mass balance studies. The rivers of the East drain a unique unglaciated sub-Arctic environment. This will allow a comparative study of weathering processes with the well known Tropical rivers of South America which drain similar rock types. This project will also provide base line information on the region most likely to be first impacted by any greenhouse warming.
