Workshop on Interdisciplinary Polar Research Based on Fast Ice-Sheet Drilling - FASTDRILL; Santa Cruz, CA, October, 2002

该奖项为一个跨学科研讨会提供了部分支持，该研讨会将生物学家、地质学家、冰川学家和古气候学家聚集在一起，讨论各种科学研究，这些研究可能受益于开发一种新的、快速的、可移动的钻探技术，以进入极地冰盖的底部。已经提到的通过这种技术可能实现的一些科学应用包括：打开通往冰下湖泊的通道、探测古冰中的生命、钻孔古测温、深冰芯的选址、用地球物理工具记录气候代用物、冰流变学研究、调查基础条件及其对基础滑动的控制、冰下地质取样和地热热流测量。本次研讨会将为冰钻、常规钻井和井下取样系统方面的专家提供一个讨论论坛，并将为美国国家科学基金会提出关于快速进入钻井技术未来方向的建议。这次研讨会将有助于研究南极洲的冰下湖泊，如沃斯托克湖。在开始研究冰下湖泊地质历史、冰川学和生物学之间的相互关系之前，有必要在采样、测量和污染控制技术方面取得进展，以便在环境无害的情况下对湖泊进行采样，以保持样本的完整性。这个讲习班将有助于技术发展，将应用于冰下湖泊的研究。

This award provides partial support for an interdisciplinary workshop to bring biologists, geologists, glaciologists and paleoclimatologists together to discuss the various scientific studies that could benefit from the development of a new, fast and mobile drilling technology for accessing the base of the polar ice sheets. Some of the scientific applications which have been mentioned which would be made possible by such technology include opening of access to subglacial lakes, detection of life in ancient ice, borehole paleothermometry, site selection for deep ice cores, logging of climate proxies with geophysical tools, ice rheology studies, investigation of basal conditions and their control on basal sliding, sampling of subglacial geology and geothermal heat flow measurements. This workshop will provide a forum for discussions with experts in ice drilling, conventional drilling and downhole sampling systems and will lead to the formulation recommendations to NSF for future directions in rapid access drilling technology. This workshop will contribute to research on sub-glacial lakes in Antarctica, such as Lake Vostok. Prior to the initiation of a research program to study the interrelationship among geologic history, glaciology and biology in sub-glacial lakes, it is necessary to make progress on sampling, measurement and contamination control technologies so that the Lake can be sampled in order to maintain sample integrity in an environmentally sound manner. This workshop will contribute to technology development that will have application to the study of subglacial lakes.
