Airborne Gravity for the CASERTZ Program

该奖项支持将航空重力与由伯德极地研究中心和美国地质勘探局联合开展的东南罗斯断面带(CASERTZ)航空磁道航空地球物理项目与机载雷达相结合。该方案将在1990-1991年和1991-1992年田野季节期间对横跨北极山脉和玛丽·伯德陆地之间的两个220×330公里区域进行调查。这项调查将由5×5公里的轨道间隔组成，旨在确定西南极埃尔斯沃斯-惠特莫尔地壳块体的运动、火山活动和变形历史，以及该块体的构造与伯德冰下盆地演化的关系。内陆罗斯湾和横跨北极的山脉。航空重力测量将提高CASERTZ计划确定地壳结构的能力，并增加模拟地壳厚度的新能力。

This award supports the integration of airborne gravity with the combined airborne radar and aeromagnetic Corridor Aerogeophysics of the Southeastern Ross Transect Zone (CASERTZ) program which will be conducted by the Byrd Polar Research Center and the USGS. This program will survey two 220 x 330 km regions between the Transantarctic Mountains and Marie Byrd Land during the 1990-1991 and 1991-1992 field seasons. The survey will consist of a 5 x 5 km track spacing and is designed to determine the motion, volcanism and deformation history of the Ellsworth-Whitmore crustal block of West Antarctica and the relationship of the tectonics of this block to the evolution of the Byrd Subglacial Basin, the Interior Ross Embayment and the Transantarctic Mountains. The airborne gravimetry will improve the capability of the CASERTZ program to define crustal structure and add a new capability to model crustal thickness.
