This award, provided by the Office of Polar Programs of the National Science Foundation, provides support for a workshop entitled "Antarctic Climate Evolution: Paleoclimate and Ice Sheet Modeling." ACE (Antarctic Climate Evolution) is a new research initiative that has recently grown out of the ANTOSTRAT (ANTarctic Offshore STRATigraphy) project. The goal of ACE is to advance the study of Antarctic climate and glacial history, through paleoclimate and ice sheet modeling studies, purposefully integrated with geological investigations of the direct and proxy record of ancient Antarctic climates and ice sheets. While ACE is not yet an official SCAR (Scientific Committee for Antarctic Research) program, a proposal will be presented to SCAR XXVII in July 2002, with the hope of establishing ACE as a fully sanctioned, international research initiative, operating under the SCAR umbrella. The ANTOSTRAT and newly appointed ACE steering committees have identified the need for members of the international climate and ice sheet modeling community, with interests in Antarctic climate and glacial history, to be identified and united with geologists working on the reconstruction of ancient Antarctic climates and ice sheets. In order to promote interaction between these groups, an ACE Paleoclimate and Ice Sheet Modeling Workshop will be held in Northampton Massachusetts, May 30-June 2, 2002. The emphasis of the workshop will be placed on evaluating the "state of the art" in modeling the climates and ice sheets of the Antarctic paleoenvironment and developing strategies for incorporating geologic data into paleoclimate, ocean, and ice sheet modeling studies. The workshop will consider a wide range of timescales, with an emphasis on Paleogene glacial inception and longer-term (10 4 year) climate change and ice sheet behavior. The workshop will better define modeler's needs, from a geologic data perspective. In turn, the modeling community will have a better understanding of the types and quality of data available for model boundary conditions, model development, and model validation. Workshop topics cover two general categories: 1) climate and ice sheet models: assessment and applications, and 2) the geologic record: boundary conditions and model validation. Participants will contribute to one of these categories by submitting an extended abstract, giving 15-minute oral presentations, and presenting volunteered posters. The meeting will be limited to 30 participants. The workshop strategy calls a roughly equal number of modelers and geologists. Lively discussion, focused on developing strategies to better incorporate geologic data into numerical modeling exercises and vice versa, is anticipated. Some workshop participants will be charged with chairing sessions, leading breakout groups, and reporting on breakout session activities. All participants are expected to engage in discussion and to contribute to the final workshop summary document. The workshop report will include extended abstracts, meeting proceedings, and a final summary report. The summary will include recommendations for future research strategies aimed at unraveling Antarctic climate and glacial evolution. A draft version of the workshop report will be presented to SCAR XXVII in July 2002. An abbreviated workshop summary will be submitted to the primary literature, while the complete document will be disseminated via hardcopy mailings, through email list servers, and via the world-wide-web. An ACE website has already been established at the University of Massachusetts (http://www.geo.umass.edu/ace). It is intended that the results of this workshop will help guide ACE related research for years to come.

该奖项由国家科学基金会极地计划办公室提供，为题为“南极气候进化：古气候和冰盖建模”的研讨会提供了支持。 ACE（南极气候进化）是一项新的研究计划，最近从Antostrat（南极海上地层）项目中发展出来。 ACE的目的是通过古气候和冰盖建模研究来推进对南极气候和冰川历史的研究，并有目的地与对古代南极气候和冰盖的直接和代理记录的地质研究有目的地融合。尽管ACE尚未是正式的疤痕（南极研究科学委员会）计划，但将于2002年7月向Scar XXVII提出一项提案，希望将ACE确立为一项全面批准的国际研究计划，并在Scar伞下运作。 Antostrat和新任命的ACE转向委员会已经确定了对国际气候和冰盖建模社区成员的需求，对南极气候和冰川历史有兴趣，并与地质学家合并并结合了与古代南极气候和冰的重建的地质学家床单。为了促进这些群体之间的互动，ACE古气候和冰盖建模研讨会将在马萨诸塞州北安普敦举行，2002年5月30日至6月2日。建模南极古环境的气候和冰盖，并制定将地质数据纳入古气候，海洋和冰盖建模研究的策略。该研讨会将考虑各种各样的时间尺度，重点是古近期的冰川成立和长期（10 4年）气候变化和冰盖行为。从地质数据的角度来看，研讨会将更好地定义建模者的需求。反过来，建模社区将更好地了解用于模型边界条件，模型开发和模型验证的数据的类型和质量。研讨会主题涵盖了两个一般类别：1）气候和冰盖模型：评估和应用，以及2）地质记录：边界条件和模型验证。参与者将通过提交扩展的摘要，提供15分钟的口头演讲并介绍志愿海报，从而为这些类别之一做出贡献。会议将限制为30名参与者。研讨会策略称大约相等的建模者和地质学家。预计，专注于制定策略以更好地将地质数据纳入数值建模练习中，反之亦然。一些研讨会的参与者将被控主持会议，领导分组讨论小组以及报告突破性会议活动。所有参与者均应进行讨论，并为最终的研讨会摘要文件做出贡献。研讨会报告将包括扩展的摘要，会议程序和最终摘要报告。该摘要将包括旨在揭示南极气候和冰川进化的未来研究策略的建议。研讨会报告的草案将于2002年7月提交给Scar XXVII。缩写的研讨会摘要将提交给主要文献，而完整的文档将通过硬拷贝邮件，通过电子邮件列表服务器以及通过世界 - 宽网络。 ACE网站已经在马萨诸塞大学（http://www.geo.umass.edu/ace）建立。本研讨会的结果将有助于指导未来几年与ACE相关的研究。
