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.

该奖项支持将于1989年3月25日至4月11日在阿根廷和智利举行的关于安第斯冰川的国际研讨会。实地考察将从乌斯怀亚开始，然后前往阿根廷拉戈、巴里洛什、奇洛岛，最后到达门多萨。20名参与者中约有一半来自南美：其他人来自北美、欧洲、澳大利亚和新西兰。主要调查人员是哥伦比亚大学Lamont-Doherty气候中心的Wallace Broecker和阿根廷火地岛乌斯怀亚CADIC(南方科学调查中心)主任Jorge Rabassa。将审查安第斯山脉南部的冰川记录，以寻找北半球和南半球冰川和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的。如果是这样的话，这只能通过大气-海洋系统的大规模重组来解释。这个国际专家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。未来的合作、多学科研究将集中于解决两个半球之间气候强迫的基本问题。
