9911617BlankenshipThis award, provided jointly by the Antarctic Geology and Geophysics Program, the Antarctic Glaciology Program, and the Polar Research Support Section of the Office of Polar Programs, provides funds for continuation of the Support Office for Aerogeophysical Research (SOAR). From July 1994 to July 2000, SOAR served as a facility to accomplish aerogeophysical research in Antarctica under an agreement between the University of Texas at Austin and the National Science Foundation's Office of Polar Programs (NSF/OPP). SOAR operated and maintained an aerogeophysical instrument package that consists of an ice-penetrating radar sounder, a laser altimeter, a gravimeter and a magnetometer that are tightly integrated with each other as well as with the aircraft's avionics and power packages. An array of aircraft and ground-based GPS receivers supported kinematic differential positioning using carrier-phase observations. SOAR activities included: developing aerogeophysical research projects with NSF/OPP investigators; upgrading of the aerogeophysical instrumentation package to accommodate new science projects and advances in technology; fielding this instrument package to accomplish SOAR-developed projects; and management, reduction, and analysis of the acquired aerogeophysical data. In pursuit of 9 NSF-OPP funded aerogeophysical research projects (involving 14 investigators from 9 institutions), SOAR carried out six field campaigns over a six-year period and accomplished approximately 200,000 line kilometers of aerogeophysical surveying over both East and West Antarctica in 377 flights.This award supports SOAR to undertake a one year and 8 month program of aerogeophysical activities that are consistent with continuing U.S. support for geophysical research in Antarctica. - SOAR will conduct an aerogeophysical campaign during the 200/01 austral summer to accomplish surveys for two SOAR-developed projects: "Understanding the Boundary Conditions of the Lake Vostok Environment: A Site Survey for Future Studies" (Co-PI's Bell and Studinger, LDEO); and "Collaborative Research: Seismic Investigation of the Deep Continental Structure Across the East-West Antarctic Boundary" (Co-PI's Weins, Washington U. and Anandakrishnan, U. Alabama). After configuration and testing of the survey aircraft in McMurdo, SOAR will conduct survey flights from an NSF-supported base adjacent to the Russian Station above Lake Vostok and briefly occupy one or two remote bases on the East Antarctic ice sheet.- SOAR will reduce these aerogeophysical data and produce profiles and maps of surface elevation, bed elevation, gravity and magnetic field intensity. These results will be provided to the respective project investigators within nine months of conclusion of field activities. We will also submit a technical manuscript that describes these results to a refereed scientific journal and distribute these results to appropriate national geophysical data centers within approximately 24 months of completion of field activities.- SOAR will standardize all previously reduced SOAR data products and transfer them to the appropriate national geophysical data centers by the end of this grant.- SOAR will convene a workshop to establish a community consensus for future U.S. Antarctic aerogeophysical research. This workshop will be co-convened by Ian Dalziel and Richard Alley and will take place during the spring of 2001.- SOAR will upgrade the existing SOAR in-field quality control procedures to serve as a web-based interface for efficient browsing of many low-level SOAR data streams.- SOAR will repair and/or refurbish equipment that was used during the 2000/01 field campaign.Support for SOAR is essential for accomplishing major geophysical investigations in Antarctica. Following data interpretation by the science teams, these data will provide valuable insights to the structure and evolution of the Antarctic continent.

该奖项由南极地质和地球物理计划、南极冰川计划和极地计划办公室极地研究支助科联合提供，为继续支持航空地球物理研究办公室(SOAR)提供资金。从1994年7月到2000年7月，根据德克萨斯大学奥斯汀分校和国家科学基金会极地计划办公室(NSF/OPP)达成的一项协议，SOAR充当了一个在南极洲完成航空地球物理研究的设施。Soar运营和维护着一套航空地球物理仪器，其中包括一台穿冰雷达探测仪、一台激光高度计、一台重力仪和一台磁力计，它们彼此以及与飞机的航空电子设备和电源组件紧密结合在一起。一组飞机和陆基GPS接收器支持使用载波相位观测值的动态差分定位。SOAR活动包括：与NSF/OPP调查员一起开发航空地球物理研究项目；升级航空地球物理成套仪器，以适应新的科学项目和技术进步；部署这一成套仪器，以完成由SARAR开发的项目；以及管理、减少和分析所获得的航空地球物理数据。为了完成NSF-OPP资助的9个航空地球物理研究项目(涉及来自9个机构的14名研究人员)，Soar在六年时间里进行了6次野外活动，在377次飞行中在南极东部和西部完成了大约20万公里的航空地球物理调查。该奖项支持Soar开展一年零8个月的航空地球物理活动计划，这与美国继续支持南极洲的地球物理研究是一致的。-SOAR将在200/01年南半球夏季开展一项航空地球物理活动，以完成对两个由SOAR开发的项目的调查：“了解沃斯托克湖环境的边界条件：未来研究的现场调查”(Co-Pi‘s Bell和Studinger，LDEO)；以及“合作研究：跨越南极东西边界的深层大陆结构的地震调查”(Co-Pi’s Weins，华盛顿大学和Anandakrishnan，阿拉巴马州)。在麦克默多配置和测试测量机后，SOAR将在靠近沃斯托克湖上的俄罗斯站的NSF支持的基地进行测量飞行，并短暂地占据东南极冰盖上的一个或两个偏远基地。-SOAR将减少这些航空地球物理数据，并产生表面高度、海床高度、重力和磁场强度的剖面和地图。这些结果将在外地活动结束后九个月内提供给各自的项目调查员。我们还将向被引用的科学杂志提交一份描述这些结果的技术手稿，并在实地活动完成后大约24个月内将这些结果分发给适当的国家地球物理数据中心。-SOAR将标准化所有以前减少的SOAR数据产品，并在这笔赠款结束前将它们转移到适当的国家地球物理数据中心。-SOAR将召开一次研讨会，为未来的美国南极航空地球物理研究建立社区共识。这次研讨会将由伊恩·达尔齐尔和理查德·艾利共同主持，并将于2001年春季举行。-SOAR将升级现有的SOAR现场质量控制程序，作为一个基于网络的界面，用于有效地浏览许多低水平的SOAR数据流。-SOAR将修理和/或翻新在2000/01年实地活动期间使用的设备。对SOAR的支持对于在南极洲完成重大地球物理调查至关重要。经过科学团队的数据解释，这些数据将为南极大陆的结构和演化提供有价值的见解。
