Antarctic Climate Evolution: Paleoclimate and Ice Sheet Modeling Workshop

该奖项由美国国家科学基金会极地项目办公室提供，为一个名为“南极气候演化：古气候和冰盖模型”的研讨会提供支持。ACE（南极气候演化）是最近从ANTOSTRAT（南极近海地层学）项目中发展起来的一项新的研究计划。ACE的目标是通过古气候和冰盖模拟研究，有目的地将古代南极气候和冰盖的直接和代理记录的地质调查结合起来，推进南极气候和冰川历史的研究。虽然ACE还不是一个正式的SCAR（南极研究科学委员会）计划，但一项提案将于2002年7月提交给SCAR第二十七届会议，希望将ACE建立为一个完全认可的国际研究计划，在SCAR的保护伞下运作。ANTOSTRAT和新任命的ACE指导委员会已经确定需要国际气候和冰盖建模社区的成员，对南极气候和冰川历史感兴趣，与地质学家一起重建古代南极气候和冰盖。为了促进这些小组之间的互动，ACE古气候和冰盖建模研讨会将于2002年5月30日至6月2日在马萨诸塞州北安普顿举行。研讨会的重点将放在评估南极古环境的气候和冰盖建模的“最新技术”，以及制定将地质数据纳入古气候、海洋和冰盖建模研究的策略。研讨会将考虑广泛的时间尺度，重点是古近系冰川开始和更长期（104年）的气候变化和冰盖行为。研讨会将从地质数据的角度更好地定义建模者的需求。反过来，建模社区将对模型边界条件、模型开发和模型验证可用数据的类型和质量有更好的理解。研讨会主题包括两大类：1)气候和冰盖模型：评估和应用；2)地质记录：边界条件和模型验证。参与者将通过提交扩展摘要，进行15分钟的口头陈述，并提交志愿海报来为这些类别中的一个做出贡献。会议人数将限制在30人以内。研讨会策略要求大致相同数量的建模师和地质学家。预计将进行热烈的讨论，重点是制定战略，以便更好地将地质数据纳入数值模拟练习，反之亦然。一些研讨会参与者将负责主持会议，领导分组讨论小组，并报告分组讨论活动。所有与会者都应参与讨论，并为最后的研讨会总结文件作出贡献。研讨会报告将包括扩展摘要、会议记录和最后的总结报告。该摘要将包括对未来研究策略的建议，旨在揭示南极气候和冰川演化。讲习班报告的草稿将于2002年7月提交SCAR第二十七届会议。将向主要文献提交一份简短的讲习班摘要，而完整的文件将通过硬拷贝邮寄、通过电子邮件列表服务器和通过万维网分发。马萨诸塞大学已经建立了一个ACE网站（http://www.geo.umass.edu/ace）。本次研讨会的成果将有助于指导今后ACE相关的研究。

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.
