Corridor Aerogeophysics of the Southeastern Ross Transect Zone (CASERTZ), Antarctica

该合同将支持在1990-91年和1991-92年野外季节对横跨南极洲山脉和玛丽伯德地之间的两个220 x 330公里区域进行机载雷达和航空磁调查。这些努力将解决国家科学院（1986年）报告“南极固体地球科学研究”中确定的罗斯样带（RTZ）的重大问题。以及提交给美国国家科学基金会的报告《美国南极岩石圈结构与演化研究计划》（SEAL）。调查将使用安装在轻型飞机上的NSF/TUD雷达和航空磁系统进行飞行。网格间距将为5公里，导航将通过无线电定位。除了冰下地形图和磁场强度图之外，还将尝试在三维空间上重建冰下衍射仪的位置。这种重建将提供有关断崖分布的新信息，从而提供该区域内构造关系的新信息，特别是当与磁结果相结合时。这些实验将由俄亥俄州立大学的伯德极地研究中心和美国地质调查局的水资源和地质部门进行。

This award will support a combined airborne radar and aeromagnetic survey of two 220 x 330 km regions between the Transantarctica Mountains and Marie Byrd Land during the 1990-91 and 1991-92 field seasons. These efforts will address significant problems identified in the Ross Transect Zone (RTZ) by the National Academy of Sciences (1986) report "Antarctic Solid Earth Sciences Research," and by the report to NSF "A Plan for a United States Program to Study the Structure and Evolution of the Antarctic Lithosphere (SEAL)." The surveys will be flown using the NSF/TUD radar and an areomagnetics system mounted in a light aircraft. The grid spacing will be 5 km and navigation will be by radiopositioning. In addition to maps of subglacial topography and magnetic intensity, attempts will be made to reconstruct the position of subglacial diffractors in three dimensions. This reconstruction should give new information about the distribution of escarpments and therefore the tectonic relationships within the region, especially when combined with the magnetic results. These experiments will be conducted by the Byrd Polar Research Center of the Ohio State University and the Water Resources and Geological Divisions of the U.S. Geological Survey.
