Recovery and Science Coordination of an Ice Core at Siple Dome, Antarctica

该奖项旨在支持从南极洲Siple Dome恢复1000米冰芯，并协调科学管理办公室的科学计划。 该项目是西南极冰盖（WAIS）计划的一部分，该计划旨在了解西南极冰盖的当前行为，并破译其过去的气候历史。 Siple Dome位于冰流C和D之间，非常适合调查沿海气候条件和Siple海岸冰流的动态，这些冰流排出南极西部冰盖。 该地点每年积累7至11厘米的冰，预计每年的冰层将可识别到至少6 000年前的年龄。 可用的气候记录的长度将延伸到至少8万年前。 该提案为Siple Dome钻探计划提供了背景，并为个人科学家（他们已经提交了单独的提案）提供了在冰芯上工作的机会。 该提案将建立一个科学协调办公室，协调参与该项目的各个组织的活动，包括国家科学基金会（NSF），极地冰芯取芯办公室（皮科），南极支持协会（阿萨）和国家冰芯实验室（NICL）。

This award is for support for the recovery of a 1000-meter ice core from Siple Dome, Antarctica and the coordination of a science management office for the scientific program. The proposed project is part of the West Antarctic Ice Sheet (WAIS) program, which seeks to understand the current behavior of the West Antarctic ice sheet and to decipher its past climate history. Siple Dome is located between ice streams C and D and is well-situated to investigate coastal climate conditions and the dynamics of the Siple Coast ice streams which drain the West Antarctic ice sheet. The annual accumulation at the site is 7 to 11 cm of ice per year and it is anticipated that annual layers will be identifiable to an age of at least 6,000 years before present. The length of the usable climate record will extend to at least 80,000 years before present. This proposal provides the background for the Siple Dome drilling program and develops the opportunity for individual scientists (who have submitted separate proposals) to work on the ice core . This proposal would establish a Science Coordination Office that would coordinate the activities of the various organizations involved in the project, including the National Science Foundation (NSF), the Polar Ice Coring Office (PICO), Antarctic Support Associates (ASA), and the National Ice Core Laboratory (NICL).
