Antarctic Ice Margin Evolution Workshop, Hobart, Tasmania, Australia, July 6-11, 1997

鲍威尔9712995 摘要南极沉积记录已经提供了高分辨率的古环境和古气候变化信息，特别是在冰缘和出口冰川波动以及湖泊和海洋生态学和地球化学方面。 一个关于环极古环境研究的SCAR-GLOCHANT（全球变化和南极）和PAGES（过去的全球变化）协调倡议详细介绍了过去25万年的情况，将为了解南极现在和未来的变化提供坚实的基础。 SCAR-PAGES计划被称为ANTIME（南极冰缘演变），将集中在两个流：流1（过去2万年）侧重于最后一次冰消和间冰期环境，气候和冰盖变化。 流2（过去25万年）将侧重于环境，气候和冰盖对冰川-间冰期循环的反应。 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，以开始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为今后的研究优先事项拟订一份科学和执行计划草案。 它将包括关于个人和国家南极计划之间协作与合作的潜在机会的信息。

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.
