International Travel: AGU Chapman Conference on the Gaia Hypothesis; Valencia, Spain; June 19-23, 2000

该奖项是为研究生和年轻科学家提供旅行支持，以参加将于2000年6月19日至23日在西班牙瓦伦西亚举行的关于盖亚假说的查普曼会议。地球科学中的一个基本知识问题是生命在调节生物圈的地球化学循环和气候中的作用。盖亚假说认为，生物群与物理和化学环境之间的相互作用足够大，可以作为生态气候控制的主动反馈能力。另一方面，许多地质时间尺度上的环境变化可以用地球化学参数来解释，而不管对生命的贡献如何。1988年举行了第一次关于盖亚假说的查普曼会议，以研究主动气候调节系统的可能性以及有机和无机环境成分之间反馈过程的相对重要性。自那次会议以来，已经间隔了十年。第二次会议的目标是集中讨论自第一次会议以来开始的工作，并更新第一次会议的材料

This award is for travel support for graduate students and young scientists to attend the Chapman Conference on The Gaia Hypothesis to be held in Valencia, Spain June 19-23 2000. A fundamental intellectual question in geosciences is the role of life in regulating the biosphere's biogeochemical cycles and climate. The Gaia hypothesis asserts that interaction between the biota and the physical and chemical environment is large enough to serve as an active feedback capacity for biogeoclimatologic control. On the other hand many environmental changes over geological time scales can be explained using geochemical arguments, regardless of the contribution to life. The first Chapman conference on the Gaia hypothesis was held in 1988 to examine the possibility of active climate regulation systems and the relative importance of feedback processes between organic and inorganic environmental components. A ten-year interval has elapsed since that conference. The objective of the second conference is to focus on the work initiated since, and to update material from the first conference
