项目摘要

Powell OPP 9712995 Abstract The Antarctic sedimentary record has already yielded high- resolution information on paleoenvironmental and paleoclimatic changes, particularly on ice marginal and outlet glacier fluctuations and in lacustrine and marine ecology and biogeochemistry. A coordinated SCAR-GLOCHANT (Global Change and the Antarctic) and PAGES (Past Global Changes) initiative on circumpolar paleoenvironmental research detailing the last 250 thousand years, will provide a solid basis for the understanding of present and future variability in the Antarctic. The coordinated SCAR-PAGES initiative, termed ANTIME (Antarctic Ice Margin Evolution), will be focused in two streams: Stream 1 (last 20 thousand years) focuses on the last deglaciation and interglacial environmental, climatic, and ice-sheet variability. Stream 2 (last 250 thousand years) will focus on the environmental, climatic, and ice-sheet response to glacial- interglacial cycles. A workshop will be held in Hobart, Tasmania, Australia during 6- 11 July, 1997, to commence the ANTIME initiative. This award supports travel for U.S. scientists to participate in the ANTIME workshop. The principal result of the workshop will be a draft science and implementation plan for future research priorities. It will include information about potential opportunities for collaboration and cooperation among individual and national Antarctic programs.

南极沉积记录已经提供了关于古环境和古气候变化的高分辨率信息，特别是关于冰缘和出口冰川波动以及湖泊和海洋生态和生物地球化学的信息。一个协调的SCAR-GLOCHANT（全球变化和南极）和PAGES（过去全球变化）倡议，详细介绍了过去25万年的环极古环境研究，将为了解南极现在和未来的变率提供坚实的基础。协调的SCAR-PAGES倡议，称为ANTIME（南极冰缘演变），将集中在两个方面：第一项（过去2万年）侧重于最后一次冰消和间冰期环境、气候和冰盖的变化。流2（过去25万年）将侧重于环境、气候和冰盖对冰期-间冰期旋回的响应。将于1997年7月6日至11日在澳大利亚塔斯马尼亚州的霍巴特举行一次讲习班，以启动安泰倡议。该奖项为参加ANTIME研讨会的美国科学家提供旅费支持。研讨会的主要成果将是未来研究重点的科学和实施计划草案。它将包括有关个人和国家南极项目之间潜在合作机会的信息。
