A Science Management Office for the U. S. Component of the International Trans Antarctic Expedition (US ITASE SMO)ûA Collaborative Pgrm of Research from S. Pole to N. Victoria Lan

该奖项支持一个科学管理办公室进行一项试点冰芯钻探和分析计划，以测试从南极洲东部获取日期准确、高分辨率的同位素和化学记录的可行性。浅冰芯将从两个地点获得：1)从南极向无法到达的极点约100公里处，作为伯德站到南极的ITASE导线[国际横贯南极科学考察]的延伸；2)在泰勒穹顶，靠近最初的深层取芯地点，以及(3)可能在AG3和AG4，作为通往这些地点的后勤导线的一部分。所有收集的岩芯都将以非常高的分辨率(约1/2厘米)进行采样，并分析主要离子。这次校准工作的结果，以及另一个正在分析稳定同位素的项目的结果，将被用来帮助规划一个更大范围的项目，目的是绘制南极东部气候变异性的空间表达图。还提供资金用于组织一个社区研讨会，以协调美国ITASE第二阶段，并每年举办一次研讨会，为期两年，专门撰写和准备美国ITASE第一阶段的科学论文。此外，东南极后续穿越活动的路线选择活动将利用卫星图像测绘进行。将编制一份摘要文件并提供给社区，以帮助规划相关的实地项目(例如，深冰雷达、降雪雷达剖面图、大气化学、冰芯、用于卫星观测的雪面特性、冰面高度和质量平衡)。

This award supports a science management office for a pilot ice-core drilling and analysis program to test the feasibility of obtaining well-dated, high-resolution isotope and chemistry records from East Antarctica. Shallow ice cores will be obtained from two locations: 1) ~100 km from South Pole towards the Pole of Inaccessibility, as an extension of the Byrd Station-to-South Pole ITASE traverse [International Trans Antarctic Scientific Expedition]; 2) at Taylor Dome, near the original deep coring site, and (3) possibly at AGO 3 and AGO 4 as part of a logistics traverse to these sites. All of the cores collected will be sampled at very high resolution (~1/2 cm) and analyzed for major ions. Results from this calibration work, along with those from another project that is analyzing stable isotopes will be used to help plan a program of larger scope, with the objective of mapping the spatial expression of climate variability in East Antarctica. Funds are also provided to organize a community workshop for coordination of the second phase of US ITASE and for one workshop per year for two years dedicated to writing and preparation of scientific papers from phase one of US ITASE. In addition, route selection activities for the follow-on traverse activities in East Antarctica will be conducted using satellite image mapping. A summary document will be produced and made available to the community to help with planning of related field programs (e.g. deep ice radar, firn radar profiling, atmospheric chemistry, ice coring, snow surface properties for satellite observations, ice surface elevation and mass balance).
