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).

这一奖项是为了支持从南极洲西普尔穹顶恢复1000米高的冰芯，并为科学计划协调科学管理办公室。拟议中的项目是西南极冰盖(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，非常适合研究沿海气候条件和排干西南极冰盖的Siple海岸冰流的动态。该地点的年积冰量为每年7至11厘米，预计在此之前，每年的冰层将可识别出至少6000年的年龄。可用气候记录的长度将至少延长到现在的8万年前。这项建议为Siple Dome钻探计划提供了背景，并为个别科学家(他们提交了单独的建议)提供了在冰芯上工作的机会。这项提议将设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)、极地冰芯办公室(PICO)、南极支助协会(ASA)和国家冰芯实验室(NICL)。
