Coordination of PEP I Research Activities

1998年，美国雪城大学在“过去全球变化”（PAGES）项目中，提出了一项关于“极-赤道-极I”（PEP I）断面研究活动协调的建议，该建议旨在为协调沿PEP I断面的研究活动寻求资金。在获得V. Markovy的赠款之前，INSTAAR于1993年建立了第一个PEP I办事处。项目领导权现已移交给G。Seltzer，锡拉丘兹大学，以及所要求的资金将用于在今后五年内继续开展PEP I办公室的活动。1998年3月，PEP I在委内瑞拉梅里达举行了一次会议，结束了沿沿着这一断面的头五年协调活动。这次会议是在1998年5月在英国伦敦举行的环境和生态系统科学伙伴关系公开科学会议之前举行的。作为这两次会议的一项成果，许多科学重点领域需要在第一阶段的下一阶段活动中继续进行协调和分析。将根据这些重点领域为一系列年度讲习班选择主题。讲习班的目的是解决以下问题：（1）美洲现存古数据的性质是什么，这些数据的关键差距在哪里，特别是在热带和南美洲？(2)目前对北方和南半球之间气候遥相关的理解如何？以及（3）除了现有项目和数据的概要之外，如何为这些主题开发一个综合的观察和解释？这些讲习班将在下一次PEPI科学会议上达到高潮，在这次会议上，将介绍和出版关于拟议主题和其他问题的综合报告，PEPI办公室在实现这些目标方面的作用将是通过提供初步重点、想法和联系方式，帮助组织者为这些讲习班获得资金。PEPI的项目领导人将继续作为PEPI I样带的代表参加PAGES和其他有关项目的会议。将通过PAGES和IGBP通讯和万维网与科学界保持联系。最后，PEP I办公室将组织下一次样带科学会议。

AbstractATM-9904344Seltzer, Geoffrey 0.Syracuse UniversityTitle: Coordination of PEP I Research ActivitiesThis proposal seeks funds for coordination of research activities along the Pole-Equator-Pole I (PEP I) transect of the Past Global Changes (PAGES) project. Prior grants to V. Markgraf; INSTAAR, established the first PEP I office in 1993. Project leadership has now been transferred to G. Seltzer, Syracuse University, and the requested funds will be used to continue the activities of the PEP I office over the next five years.In March 1998 a meeting of PEP I was held in Merida, Venezuela, which ended the first five years of coordinated activity along this transect. The meeting preceded the open science meeting of PAGES, which was held in London, England, in May 1998. As an outcome of these two meetings, many areas of scientific focus warrant continued coordination and analysis during the next phase of PEP I activity. Based on these areas of emphasis, themes will be chosen for a series of annual workshops. The intent of the workshops will be to address the following questions: (1) what is the nature of the extant paleodata in the Americas and where are the critical gaps in these data, especially in the tropics and South America? (2) what is the current understanding of climatic teleconnections between the northern and southern hemispheres with regard to these overriding themes? and (3) other than a compendium of current projects and data, how can a synthesis of observations and interpretations be developed for these themes? These workshops will culminate in the next PEPI science meeting at which these syntheses on the proposed themes as well as other questions will be presented and published.The role of the PEP I office in carrying out these objectives will be to help organizers obtain funding for these workshops by providing preliminary focus, ideas, and contacts. The project leader of PEPI will continue to act as the representative of the PEP I transect to meetings of PAGES and other related projects. Contact with the scientific community will be maintained through the PAGES and IGBP newsletters and through the World Wide Web. Finally, the PEP I office will organize the next science meeting of the transect.
