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，以测试从东南极洲获得准确年代、高分辨率同位素和化学记录的可行性。浅冰芯将从两个地点获得：1)从南极向不可达极点方向约100公里，作为伯德站到南极ITASE导线的延伸[国际跨南极科学考察]；2)在Taylor Dome，靠近原始的深取心地点，以及(3)可能在AGO 3和AGO 4作为后勤穿越这些地点的一部分。收集到的所有岩心都将以非常高的分辨率（~1/2 cm）进行采样，并分析主要离子。这项校准工作的结果，连同另一个正在分析稳定同位素的项目的结果，将用于帮助规划一个更大范围的项目，其目标是绘制南极洲东部气候变化的空间表现。还提供资金组织一个社区讲习班，以协调美国信息技术援助计划第二阶段的工作，并每年举办一个为期两年的讲习班，专门编写和编写美国信息技术援助计划第一阶段的科学论文。此外，东南极洲后续穿越活动的路线选择活动将使用卫星图像测绘进行。将编制一份概要文件并提供给社区，以帮助规划相关的实地方案（例如，深冰雷达、雪雷达剖面、大气化学、冰芯、用于卫星观测的雪表面特性、冰表面高程和质量平衡）。

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).
