Antarctica's Gamburtsev Province (AGAP) Project - Airborne gravity data (2007-2009)
GB/NERC/BAS/PDC/01310

Summary

Abstract:
Aerogravity data collected as part of the seven nation Antarctica's Gamburtsev Province (AGAP) expedition during the International Polar Year 2007-2009, and used to acquire a detailed image of the ice sheet bed deep in the interior of East Antarctica.

Airborne geophysical methods were used to understand the fundamental structure shrouded beneath Dome A. Two twin Otter aircraft - one BAS, one United States Antarctic Program (USAP)- equipped with ice-sounding radars, laser ranging systems, gravity meters and magnetomemeters, operated from camps located on either side of Dome A.

Airborne gravity measurements were acquired using LaCoste and Romberg air-sea gravimeter modified by ZLS Corporation, which is well-proven for Antarctic field work. A land-gravimeter was used to tie the still readings on the aircraft with the absolute gravity value at McMurdo Station.
