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.

POWELL OPP 9712995摘要南极沉积记录已经获得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。关于环极古环境研究的协调的SCAR-GLOCHANT(全球变化与南极)和PAGE(过去的全球变化)倡议，将为理解南极现在和未来的变异性提供坚实的基础。协调的SCAR-PAGE倡议，称为ANTIME(南极冰缘演化)，将集中在两个流：流1(过去两万年)侧重于最后一次冰川消融和间冰期环境、气候和冰盖的可变性。流2(过去25万年)将侧重于环境、气候和冰盖对冰期-间冰期循环的响应。将于1997年7月6日至11日在澳大利亚塔斯马尼亚的霍巴特举办一次讲习班，以启动ANTIME倡议。该奖项支持美国科学家参加ANTIME研讨会的旅行。讲习班的主要成果将是未来研究优先事项的科学和实施计划草案。它将包括关于个人和国家南极计划之间合作与合作的潜在机会的信息。
