Strapdown aerogravity survey across the Brunt Ice Shelf, 2017
GB/NERC/BAS/PDC/01073

Summary

Abstract:
This data set contains strapdown aerogravity data collected during an airborne radar survey of the Brunt Ice Shelf as part of the NERC/BAS Life Time of Halley project. Unlike traditional stabilised platform gravity surveys strapdown gravity techniques, using an Inertial Measurement Unit (IMU) rigidly attached to the aircraft as the sensor, allow collection of gravity data during draped or turbulent flight. This was a key factor allowing for data collection during a dedicated radar survey. The survey was flown draped with an average height above the ice surface of 420m, and includes 4716 km of new data. The aircraft used was the BAS aerogeophysicaly equipped twin otter VP-FBL. Data are available in both Geosoft database (.gdb) and ASCII file formats (.xyz).
