US Support for Central Scientific Co-ordination and Integration Activities of the International Geosphere- Biosphere Programme

该奖项将继续支持国际秘书处和国际地圈-生物圈方案的核心业务。IGBP由国际科学联合会理事会（ICSU）于1986年建立，旨在促进国际合作研究，以描述和理解构成整个地球系统关键部分的相互作用的物理、化学和生物过程，以及这些组成部分内部和之间发生的变化。IGBP赞助了七个核心项目，每个项目都涉及一个对理解全球生物地球化学循环具有重要意义的科学问题。这些核心项目包括研究大气化学、海洋生物地球化学、海岸带过程、陆地生态系统和土地利用、水文循环的生物圈方面以及过去的全球变化。IGBP还支持国际数据和信息管理活动，并共同发起了全球变化分析、研究和培训系统（START）。通过该奖项，NSF将代表所有参与美国全球变化研究计划的机构，为IGBP提供三年的资金支持。美国的支持与其他40多个国家的捐助相匹配。

This award provides continued support for the International Secretariat and core operations of the International Geosphere-Biosphere Programme (IGBP). The IGBP was established in 1986 by the international Council of Scientific Unions (ICSU) in order to facilitate international collaborative research that would describe and understand the interactive physical, chemical, and biological process that constitute critical parts of the total Earth system and the changes that occur within and among those components. The IGBP sponsors seven core projects, each of which addresses a scientific question of major importance for an understanding of global biogeochemical cycles. These core projects include studies of atmospheric chemistry, ocean biogeochemistry, coastal zone processes, terrestrial ecosystems and land use, biospheric aspects of the hydrologic cycle, and past global changes. The IGBP also supports international data and information management activities, and it co-sponsors the Global Change SysTem for Analysis, Research and Training (START). Through this award, NSF will provide three years of funding for continued support of the IGBP on behalf of all agencies participating in the U.S. Global Change Research Program. U.S. support is matched by contributions from more than 40 other nations.
