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

该奖项用于资助研究生和年轻科学家参加2000年6月19日至23日在西班牙巴伦西亚举行的盖亚假说查普曼会议。地球科学中一个基本的智力问题是生命在调节生物圈的生物地球化学循环和气候方面的作用。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，足以作为生物地理气候控制的主动反馈能力。另一方面，地质时间尺度上的许多环境变化可以用地球化学论点来解释，而不考虑对生命的贡献。1988年举行了关于盖亚假说的第一次查普曼会议，以审查活跃的气候调节系统的可能性以及有机和无机环境组成部分之间反馈过程的相对重要性。自那次会议以来，已经过去了十年。第二次会议的目标是侧重于自第一次会议以来启动的工作，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
