Airborne Gravity for the CASERTZ Program

该奖项支持将空中重力与 机载雷达和航磁走廊联合 罗斯样带东南部的航空地球物理 （CASERTZ）计划，将由伯德极地进行 研究中心和USGS。 该计划将调查两个 220 x 330公里的区域，位于跨南极山脉之间 和玛丽伯德地在1990-1991年和1991-1992年实地考察期间 季 调查将包括一个5x 5公里的轨道 间隔，旨在确定运动，火山活动 埃尔斯沃-惠特莫尔地壳的构造和变形历史 西南极洲板块与 该地块的构造与伯德的演化 冰下盆地、罗斯湾内陆和 横贯南极山脉。 航空重力测量将 提高CASERTZ计划的能力， 地壳结构，并增加了新的能力，以模拟地壳 厚

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.
