High-Latitude Southern Ocean Paleontology Workshop

摘要植物、动物和原生生物化石的研究为地质研究提供了宝贵的年代和古环境资料。古生物学家正在积极研究南大洋和南极地区的进化和环境变化的地层记录，以解决与4000多万年前南极冰盖发展有关的气候变化问题，以及生命对逐渐冷却和冰盖进退的反应。地质记录中存在许多缺口。最近和未来的努力目标是通过地层钻探来填补一些主要的空白。Cape Roberts项目（CRP）是最近的钻探工作，目标是恢复1亿至3000万年前的记录。这将建立在最近在维多利亚陆地盆地边缘（CIROS & &； MSSTS）和海洋钻探计划（ODP）在南大洋的钻探工作的基础上。新的CRP计划将把重点放在东南极洲冰盖的早期历史和冰盖形成之前的条件上，当时该地区要暖和得多。将于1996年5月21日至23日在新西兰惠灵顿举行一次讲习班，讨论与南极洲生物群和南部高纬度地区过去的环境变化有关的广泛问题。该研讨会将审查目前的知识状况，并为科学家制定未来研究的战略和方法提供一个论坛。对这次讲习班至关重要的是发展和整合生物地层学分区方案。将比较来自南大洋和澳大利亚、新西兰和南美洲周围大陆边缘的参考剖面，以便为1996年和1997年在罗伯茨角的钻探做准备。该奖项为美国古生物学家提供旅费支持，这些古生物学家涵盖了一系列化石组，并具有相当的DSDP和ODP经验，他们可以参加研讨会，并与参与罗伯茨角项目的其他国家的古生物学家和地层学家直接交流。这项工作将为罗伯茨角项目岩心的生物地层学和古生物学分析提供更连贯的方法，并为解决与南部高纬度地区生命记录和环境变化有关的更大问题提供一个论坛。

Harwood 9634616 Abstract Information derived from the study of fossil plants, animals, and protists provides valuable data on age and paleoenvironment in geological studies. Paleontologists are actively studying the stratigraphic record of evolution and environmental change in the Southern Ocean and Antarctic area, in order to address questions regarding climate change associated with the development of the Antarctic Ice Sheet more than 40 million years ago and the response of life to progressive cooling and ice sheet advance and retreat. Many gaps exist within the geologic record. Recent and future efforts are targeted at filling some of the major gaps through stratigraphic drilling. The Cape Roberts Project (CRP) is the most recent drilling effort, with a target to recover a record from 100 to 30 million years ago. This will build on recent drilling efforts on the margin of the Victoria Land Basin (CIROS & MSSTS) and in the Southern Ocean by the Ocean Drilling Program (ODP). The new CRP initiative will focus on the early history of ice sheets in East Antarctica and the conditions there prior to the development of the ice sheet, when this region was much warmer. A workshop to address broad issues related to AntarcticaOs biota and past environmental change in the southern high-latitudes will be held on 21 to 23 May, 1996 in Wellington, New Zealand. The workshop will review the current state of knowledge and provide a forum for scientists to develop strategies and approaches for future research. Of critical importance to this workshop will be the development and integration of biostratigraphic zonal schemes. Reference sections from the Southern Ocean and surrounding continental margins of Australia, New Zealand and South America will be compared in preparation for the 1996 and 1997 drilling at Cape Roberts. This award provide travel support U.S. paleontologists, covering a range of fossil groups and considerable DSDP and ODP experience, to particip ate in the workshop and communicate directly with paleontologists and stratigraphers from other countries involved with the Cape Roberts Project. This effort will enable a more coherent approach to the biostratigraphy and paleontological analysis of Cape Roberts Project cores and provide a forum to address larger issues related to the record of life and environmental change in the southern high-latitudes.
