U.S.-Argentina: Andean Glaciation Field Conference; March 25-April 11, 1989

该奖项支持将于1989年3月25日至4月11日在阿根廷和智利实地举行的关于安第斯冰川作用的国际讲习班。实地考察将从乌斯怀亚开始，前往阿根廷湖湖、巴里洛切、奇洛伊岛，最后在门多萨结束。20名参与者中约有一半来自南美，其余来自北美、欧洲、澳大利亚和新西兰。主要研究人员是哥伦比亚大学拉蒙特-多尔蒂气候中心的华莱士·布鲁克和火地岛乌斯怀亚南部科学调查中心主任豪尔赫·拉巴萨，阿根廷。将审查南安第斯山脉的冰川记录，以寻找北半球和南半球冰川与气候循环之间联系的证据。现有的冰川和古植物学证据表明，这些事件可能是同步发生的。如果是这样的话，这只能用大气-海洋系统的大规模重组来解释。这个国际专家小组将审查有争议的实地证据，这些证据构成了安第斯山脉冰川历史的基础。未来的多学科合作研究将集中于解决半球间气候强迫的基本问题。

This award supports an international workshop on Andean glaciation to be held in the field in Argentina and Chile from March 25 to April 11, 1989. The fieldtrip will begin in Ushuaia, proceed to Lago Argentina, Bariloche, Isla de Chiloe and end in Mendoza. About half of the 20 participants are from South America: the others from North America, Europe, Australia and New Zealand. The principal investigators are Wallace Broecker of the Lamont-Doherty Climate Center at Columbia University and Jorge Rabassa, Director of CADIC (Southern Center for Scientific Investigation) in Ushuaia, Tierra del Fuego, Argentina. The glacial record in the southern Andes will be reviewed for evidence of a link between glacial and climatic cycles in the northern and southern hemispheres. Available glacial and paleobotanical evidence suggest that these events may be synchronous. If so, this can only be explained by a massive reorganization of the atmosphere-ocean system. This international group of experts will review controversial field evidence which forms the basis for the history of Andean mountain glaciation. Future cooperative, multidisciplinary research will focus on solving the basic problem of climate forcing between the hemispheres.
