ITASE Synthesis Workshop

Mayewski 0829227该奖项支持一个研讨会，汇集参与国际跨南极科学考察（ITASE）的科学家。 自1999年以来，美国一直支持穿越东南极洲和西南极洲的计划（US ITASE）。美国ITASE是ITASE多国努力的一部分，旨在了解南极洲和南大洋过去200-1000多年的气候变化。 ITASE是在南极研究科学委员会的主持下组织的，目前由21个国家组成。ITASE的国际代表过去曾举行过几次会议，讨论国家导线测量计划;协调努力;综合结果;发展数据解释的统计和其他技术。讲习班将为综合全舌区ITASE过去气候重建的进程提供额外的动力。通过南极研究科学委员会赞助的Ice READER数据库，可以获得所有ITASE和其他冰芯站点的新汇编，讲习班的一个目标是更新这一元数据清单。研讨会还将重点确定过去200-1000多年来影响南极和周围海洋的气候变化特征，以便为评估政府间气候变化专门委员会（IPCC）预测的该地区约4-6摄氏度变暖所导致的巨大变化提供基础。这次研讨会的成果也将成为ITASE冰芯研究人员、气象学家、海洋学家和气候模拟人员之间未来合作的基础，这些合作源于国际冰芯科学伙伴关系（IPICS）和国际极地年（IPY）等国际倡议。最后，研讨会的结果将列入即将发表的由南极研究科学委员会发起的题为“南极气候变化与环境”的文件。

Mayewski0829227This award supports a workshop to bring together scientists involved in the International Trans-Antarctic Scientific Expedition (ITASE). Since 1999 the US has supported a program of traverses across both East and West Antarctica (US ITASE). US ITASE is part of the ITASE multi-national effort to understand the past 200-1000+ years of climate change over Antarctica and the Southern Ocean. ITASE is organized under the auspices of Scientific Committee for Antarctic Research (SCAR) and now comprises twenty-one countries. The international representatives from ITASE have met several times in the past to discuss national traverse plans; coordinate efforts; synthesize results; and develop statistical and other techniques for the interpretation of data. The workshop will provide additional momentum to the process of synthesizing the Antarctic-wide ITASE reconstruction of past climate. An emerging compilation of all ITASE and other ice core sites is available through the Ice READER database sponsored by SCAR and one workshop goal is to update this metadata listing. The workshop will also focus on identifying the characteristics of climate change that have impacted the Antarctic and surrounding ocean in the past 200-1000+ years in order to provide a basis for assessing the dramatic changes expected as a consequence of the ~4-6 degrees C warming projected for this region by the Inter-governmental Panel for Climate Change (IPCC). Results from this workshop will also form the basis for future collaborative efforts between ITASE ice core researchers, meteorologists, oceanographers, and climate modelers stemming from international initiatives such as the International Partnerships in Ice Core Sciences (IPICS) and the International Polar Year (IPY). Finally, workshop findings will be included in the forthcoming document: "Antarctic Climate Change and the Environment" initiated by SCAR.
