High-Latitude Southern Ocean Paleontology Workshop

哈伍德9634616摘要从植物、动物和原生生物化石研究中获得的信息在地质学研究中提供了有关年龄和古环境的宝贵数据。古生物学家正在积极研究南大洋和南极地区演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空白。最近和今后的努力旨在通过地层钻探来填补一些主要空白。罗伯茨角项目(CRP)是最新的钻探工作，目标是恢复1亿至3000万年前的记录。这将建立在维多利亚陆地盆地边缘(Ciros&amp；MSSTS)和大洋钻探计划(ODP)最近在南大洋进行的钻探工作的基础上。新的CRP倡议将侧重于南极东部冰盖的早期历史，以及该地区在冰盖形成之前的条件，当时该地区要温暖得多。将于1996年5月21日至23日在新西兰惠灵顿举办一次讲习班，讨论与南极洲生物群和南部高纬度过去的环境变化有关的广泛问题。讲习班将审查目前的知识状况，并为科学家提供一个论坛，为未来的研究制定战略和方法。对该讲习班至关重要的是生物地层分区方案的制定和整合。将对南大洋和澳大利亚、新西兰和南美洲周围大陆边缘的参考剖面进行比较，为1996年和1997年在罗伯茨角进行钻探做准备。该奖项为美国古生物学家提供旅行支持，他们涵盖了一系列化石群，并拥有丰富的DSDP和ODP经验，他们参加了研讨会，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。这一努力将使对罗伯茨角项目岩芯的生物地层学和古生物学分析采取更加协调一致的方法，并提供一个论坛，以解决与南部高纬度地区的生命记录和环境变化有关的更大问题。

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.
